2017 - Week 41 Winners

Tyrell Hatton (ranked 8th by Golf Predictor) won the Italian Open on the European PGA Tour. The 25 year old Englishman continued his fine recent form by winning for the second week running. After a slow start Sunday, Hatton reeled off four consecutive birdies on the back nine to catch leaders Ross Fisher and Kiradech Aphibarnrat with three holes to go. He left it late to seal the win though, holing a 20 footer on the last for the winning birdie. Our top ranked player, John Rahm, finished in tied 15th and we had seven of the top fifteen plus ties (7/20).

Pat Perez (ranked 5th by Golf Predictor) won the CIMB Classic on the US PGA Tour. The 41 year old American won his third tour title with an impressive display in Malaysia. Perez lead by four shots overnight and finished with ten straight pars to coast home and preserve his cushion over the field. Since I had backed/tipped him at 45/1, I was almost as happy as Perez after his victory! Our top ranked player, Hideki Matsuyama, finished in tied 5th in a welcome return to form and we had nine of the top seventeen plus ties (9/20).

2017 - Week 41 Predictions/Statistics Online

The predictions and statistics for this week, the CIMB Classic (US PGA Tour) and the Italian Open (European PGA Tour) are now available on Golf Predictor. Like the past few years, the Kuala Lumpur Golf and Country Club is hosting the US Tour. There are a few big names in the Malaysian event this year, including Hideki Matsuyama and double defending champion Justin Thomas, so it should make for a good week of golf. Meanwhile, the latest Rolex Series event in Italy has attracted Spanish heavyweights Sergio Garcia and Jon Rahm and a supporting cast of tour regulars.

2017 - Week 40 Winners

Tyrell Hatton (ranked 5th by Golf Predictor) won the Alfred Dunhill Links Championship on the European PGA Tour. The 25 year old Englishman became the first man to successfully defend his title with another impressive display in Scotland. Leading by five overnight and starting fast, it looked like it was going to be a doddle for Hatton. However, Ross Fisher went on a charge and had a chance of a 59, before settling for a course record 61. That meant Hatton couldn't relax down the stretch and had to settle for a three shot win. Our top ranked player, Rory McIlroy, failed to sign off in 2017 in style and finished in tied 63rd. Overall, we only had seven of the top fifteen plus ties (7/24*).

Brendan Steele (ranked 20th by Golf Predictor) won the Safeway Open on the US PGA Tour. The 34 year old American also became the first man to successfully defend his title in California. In the difficult conditions on Sunday, Steele shot an impressive 69 (-9) to come from two back and win by two shots in the end. Our top ranked player, Phil Mickelson, somehow finished in tied 3rd, despite being all over the place off the tee! Overall, we had fifteen of the top seventeen plus ties (15/27). 


*Withdrawals mean Bourdy & Warren are promoted to the top 24 of the GP Rankings.

2017 - Week 40 Predictions/Statistics Online

The predictions and statistics for this week, the Alfred Dunhill Links Championship (European PGA Tour) and the Safeway Open (US PGA Tour), are now available on Golf Predictor. It's the first event of the new 2017/18 US PGA Tour season, but after the Presidents Cup last week, there not many big guns trying to get their new campaigns off to a flying start.While there aren't many big golfing names teeing it up in either event, Rory McIlroy and a solid list of European Tour stalwarts are teeing it up on the three courses in Scotland. It looks like golfers and celebrities alike have the usual difficult weather conditions for the event!

2017 - Week 39 Winner

Paul Dunne (ranked 23rd by Golf Predictor) won the British Masters supp. by Sky Sports on the European PGA Tour. The 24 year old Irishman claimed his maiden tour title with a brilliant final day performance at Close House. Dunne closed with 61 (-9), to hold off the fast finishing Rory McIlroy. After birdieing the penultimate hole, Dunne gave himself a two shot cushion on the par three finishing hole. However, after he missed the green, the door was slightly ajar for McIlroy. Dunne then proceeded to pitch in to win in style and by three shots in the end. Our top ranked player, Sergio Garcia, missed the cut, and we had nine of the top fifteen plus ties (9/19).

There was no individual stroke play event on the US PGA Tour this week as it is the short close season (and the week of the Presidents Cup!).

Monday, 25 September 2017

2017 - Week 39 Predictions/Statistics Online

The predictions and statistics for this week, the British Masters supp. by Sky Sports (European PGA Tour) are now available on Golf Predictor. There is no event on the US PGA Tour this week as it is still the short close season and the Presidents Cup is being held (Golf Predictor is not suitable for team matchplay events). Lee Westwood has managed to attract some big European names to the event in England, where the tournament has moved to yet another new course and another new host. This doesn't make the task of forecasting it any easier!

Sunday, 24 September 2017

2017 - Week 38 Winners

Lucas Bjerregaard (ranked 37th by Golf Predictor) won the Portugal Masters on the European PGA Tour. The 26 year old Dane won his first tour title with an impressive front running display in Vilamoura. Leading by one overnight, Bjerregaard shot an eight birdie 65 (-6) to put his poor season behind him and win by four shots. Our top ranked player, Thomas Pieters, finished in 74th and we had only six of the top twenty plus ties (6/24*) at the birdiefest in the Algarve.

Xander Schauffele (ranked 30th by Golf Predictor) won the Tour Championship on the US PGA Tour. The 23 year old American rookie capped a fantastic début season by taking the prestigious title at East Lake. Schauffele showed nerves of steel to hold off a quality field, pipping Justin Thomas with a short birdie putt on the last. Runner-up  Thomas had the consolation of banking the $10 million FedEx Cup jackpot. Our top ranked player, Dustin Johnson, finished in 74th and we had twelve of the top seventeen plus ties (12/18) in the restricted field event.  


 *Gallacher withdrew, promoting Burmester to the top 24 of the GP rankings.

Monday, 18 September 2017

2017 - Week 38 Predictions/Statistics Online

The predictions for this week, the Tour Championship (US PGA Tour) and the Portugal Masters (European PGA Tour) are now available on Golf Predictor. Only the top thirty in the FedEx Cup rankings are playing in the US season finale this week and it's the usual cream of the crop,with some exceptions e.g. defending FedEx Cup champion Rory McIlroy. The field in Portugal is more modest, but there are a significant number of the bigger regulars on the European Tour and a few US based Europeans playing in the Algarve.

2017 - Week 37 Winners

Romain Wattel (ranked 61st by Golf Predictor) won the KLM Open on the European PGA Tour. The 26 year old Frenchman overcame some poor recent form to land his maiden tour title. Wattel, who played steady golf on Sunday, was helped somewhat by overnight leader Aphibarnrat, who double bogeyed two of the last four holes to finish three shots behind. Our top ranked player, Bernd Wiesberger, finished in tied 9th and in an event where many of the bigger names failed to perform, we had only three of the top nine plus ties (3/13).

Marc Leishman (ranked 20th by Golf Predictor) won the third event of the FedEx Cup play-offs, the BMW Championship. The 33 year old Australian won his third tour title with an impressive wire to wire victory at Conway Farms. Leading by five overnight, Leishman was put under some pressure by Justin Rose and Rickie Fowler before steadying the ship and preserving his lead in the end. After a lacklustre opening three days, our top ranked player, Dustin Johnson, finished strongly with a 64 (-7) for tied 33rd. Overall, we had twelve of the top twenty plus ties (12/26).

Tabs & Stats Added to Golfer Page


New Golfer page for Rory McIlroy showing new tabs. The data and chart links in the Season Segment/Region tab are displayed.

Spider Chart for McIlroy's Region Performance, showing relatively poor performance in his home region and to a lesser extent, the Eastern US region.

I am pleased to announce the addition of tabs and more statistics to the Golfer page on Golf Predictor. This page is accessible from clicking on the icon beside a golfer's name on one of the many data pages or the Golfers page in the Information menu. While this has been planned for some time, I also got some user feedback which prompted me into action! The new stats added to this page are:
  1. All the prediction/field stats records in the system for the golfer in one place, i.e. his stats ahead of each event.
  2. All the DraftKings records in the system for the golfer in one place, i.e. his DraftKings stats ahead of each event.
  3. All the strokes gained stats records in the system for the golfer in one place, i.e.. his strokes gained stats ahead of each event.
  4. The season segment (early/mid/late) stats in the system for the golfer, i.e. his up to date data in each part of the GP Season.
  5. All the region stats in the system for the golfer, i.e. his performance in each region he has played in.
To facilitate the addition of all these new stats, I have added tabs to the Golfer page. The four new tabs can be seen in the first screenshot above, which shows the Season Segment/Region tab for for Rory McIlroy. The existing information on the Golfer page was largely focussed on the results and this is now almost all located in the first tab. The only exception is the list of season statistics records, which have been moved to the same tab as the new predictions/field stats table. All these newly added stats were already in the system, but displayed in tournament focussed tables with other golfers (i.e. the field). These new tables added to the Golfer page focus on the golfer and show all his stats in one place. This will save you a lot of time should you be interested in the data for a particular golfer only. Some notes on these changes to the Golfer page:
  1. Most of the tab titles have been abbreviated to save space, particularly for smaller devices such as phones or tablets.
  2. Only the DraftKings/strokes gained data in the database is shown. These are not generally stored forever and may be cleared out at the end of every GP Season.
  3. Most of these newly displayed stats are based on stats generated or used for the prediction/field stats before a tournament. This is particularly relevant for region stats, which do not include the result of the actual tournament itself (if finished) in that region. However, in this case, you can hover over the region to see the result of the last tournament in the region. You can also click on the region name for see the complete Prediction Data page for the golfer for that tournament, which contains his results and further stats for that region.
  4. There are no column keys for the tables on these new tabs. However, most of the abbreviations should be self evident and are almost identical to those on the tables with the same data for the field. For example, the new DraftKings table has very similar columns to the existing Rankings (DFS) page, so you can refer to the key on this table if you are unsure. However, I have renamed some of the columns on these new player centric tables on the Golfer page to make them more obvious.
  5. Two spider charts have been added to the Golfer page, one existing chart for the season segment stats (already available on the Season Segment page) and one new chart for comparing region stats easily. The links for these new charts can be seen in the first screenshot above. This new chart is shown in the second screenshot above for Rory McIlroy. Interestingly, it shows that, despite a few wins, McIlroy's worst performances by a considerable margin over almost all other regions over the past five years have been in his home region*. Also, it shows that in the US, he does worst in the Eastern region, which includes major venues like Oakmont, Baltusrol and Congressional.
  6. You may have to refresh the GP site files in your browser cache to see the new tabs properly. The easiest way to do this on Windows is to press Ctrl+F5 on any GP page. Alternatively, you can clear your browser cache, but this will also affect other sites.

In addition to facilitating the display of large amounts of data, these tabs also allow for more modular development. Instead of one large monolithic page and associated code, I can now divide up the page into logical (and reusable, if necessary) chunks and use one per tab. Therefore, over the next while, I plan to add tabs to other pages on the site, including the Tournament and the main Prediction Data pages. In doing so, no stats will disappear, but some may be moved around, e.g. the course history data panel and associated results might be shown together in one tab. At the moment, the associated results are far down the prediction data page from the course history data panel.

The new regions spider chart brings the total number of charts on the site to 487 and these new stats should be very useful in helping you pick good golfers for your fantasy golf, DFS or betting needs. For the first time, a golfer's statistics are displayed in one place and information such as his relative performance in different parts of the world is displayed. 

Only subscribers can view this new chart and the new golfer centric data tables, so sign up today and reap the full benefits of Golf Predictor, the premium professional golf statistics site.


*Luckily, GP uses the British Isles as a region, which includes Britain and the whole island of Ireland. This allows me to dodge the political minefield!!

2017 - Week 37 Predictions/Statistics Online

The predictions/stats for this week, the BMW Championship (US PGA Tour) and the KLM Open (European PGA Tour) are now available on Golf Predictor. It's the third leg of the FedEx Cup play-offs in the US this week and the pressure will be on to qualify for the lucrative Tour Championship next week. As usual, the bigger names are still in FedEx Cup contention in America, but there still are a few European players in the top fifty in the world rankings teeing it up in the Netherlands this week.

2017 - Week 36 Winner

Matthew Fitzpatrick (ranked 7th by Golf Predictor) won the Omega European Masters on the European PGA Tour. The 23 year old Englishman won his fourth tour title by defeating Scott Hend in a play-off in the scenic Swiss mountains. Fitzpatrick trailed third round leader Hend by four shots overnight, but finished strongly to briefly overtake the Australian. However, he bogeyed the penultimate hole and finished level with last year's runner-up in a play-off. Hend, who had a birdie putt to win on the last hole in regulation, also missed a short putt n the second extra hole which was to prove costly. After finding trouble off the tee, Hend could only bogey the third extra hole and Fitzpatrick took the title with a par. Our top ranked player, defending champion Alexander Noren, finished in tied 6th and in an event where many bigger names failed to perform, we had only five of the top sixteen plus ties (5/19). 

There was no event on the US PGA Tour this week.

Tuesday, 5 September 2017

2017 - Week 36 Predictions/Statistics Online

The predictions and statistics for this week, the Omega European Masters (European PGA Tour), are now available on Golf Predictor. As usual, there is also a decent field of tour members assembled for the popular track in Switzerland this week. The field is led by world number twelve and defending champion Alex Noren, who is joined by several other stalwarts of the European Tour. There is no event on the US PGA Tour this week as it is the rest week in the FedEx Cup play-offs..

2017 - Week 35 Winners

Haydn Porteous (ranked 41st by Golf Predictor) won the D+D REAL Czech Masters on the European PGA Tour. The 23 year old South African won his second tour title in a final day battle with third round leader Lee Slattery. Although trailing by two shots overnight, Porteous reeled in Slattery straight away with two opening birdies, and despite a slight mid-round wobble, reclaimed the initiative and held on to win by two in the end. Our top ranked player, Thomas Pieters, had a disappointing final round (which included a six putt!) and finished 66th Overall, in an event where almost all of the bigger names didn't perform, we had only a disappointing two of the top eighteen plus ties (2/21) in total. 

Justin Thomas (ranked 14th by Golf Predictor) won the Dell Technologies Championship on the US PGA Tour. The 24 year old American won his fifth title of a memorable season with a three shot win over Jordan Spieth. After an amazing front nine on Sunday where most of the top players came out all guns blazing, the scoring cooled considerably on the back nine. Most fell away down the stretch,  including Spieth, who had to chase his good friend late on. That allowed Thomas to win his first FedEx Cup event reasonably comfortably in the end. Our top ranked player, Dustin Johnson, finished in tied 18th and we had nine of the top eighteen plus ties (9/21).

Monday, 28 August 2017

2017 - Week 35 Predictions/Statistics Online

The predictions and statistics for this week, the Dell Technologies Championship (US PGA Tour) and the D+D REAL Czech Masters (European PGA Tour), are now available on Golf Predictor. As usual, there is a strong field in Boston for the second play-off event, with seventeen of the top ten in the world rankings jockeying for position in the FedEx Cup. Meanwhile, the field in the Czech Republic is not quite as impressive, with only two members of the top fifty in the world playing in Prague.

Sunday, 27 August 2017

2017 - Week 34 Winners

Julian Suri (ranked 15th by Golf Predictor) won the Made in Denmark on the European PGA Tour. The 26 year old American won his first tour title in a final day battle with David Horsey. After opening with five birdies in the front nine on Sunday, Suri overturned Horsey's two shot overnight lead. However, the Englishman hit back and it was nip and tuck until the final tee. Trailing by a shot, Horsey had a nightmare trying to put pressure on the leader, losing his first ball left and finding the water right with his provisional. That effectively handed the title to Suri, who could relax up the last and finish with a blemish free 64 (-7). Our top ranked player, defending champion Thomas Pieters, disappointingly missed the cut and we had only seven of the top nineteen plus ties (7/22).

Jordan Spieth (ranked 3rd by Golf Predictor) won The Northern Trust on the US PGA Tour. The 24 year old American won his twelfth tour title in a close battle down the stretch with world number one Dustin Johnson. Despite leading by five at one stage early on Sunday, Spieth was caught by DJ and the duo fought it out on the back nine for the title. It looked like it was going to be decided on the final hole after DJ found deep rough off the tee and was forced to lay up. However, the world number one showed great resolve to drain an eighteen foot putt for par and force a play-off. On the first extra hole, DJ played the eighteenth perfectly with a fabulous drive, flick with a wedge and five foot putt to land the title. DJ was our top ranked player and we had a whopping sixteen of the top twenty plus ties (16/24) in total.

New Strokes Gained Chart Added to Golf Predictor

Field Strokes Gained chart for 2017 Northern Trust, showing Rickie Fowler's data

As above, with highlighted good performance areas

I am pleased to announce a useful new strokes gained chart for Golf Predictor. This new chart is available on the Rankings (Strokes Gained) page on the Predictions menu and it shows at a glance the strokes gained tee to green and strokes gained putting for the field. This new chart is shown above for the 2017 Northern Trust and shows the strokes gained tee to green on the vertical axis and strokes gained putting on the horizontal axis. As shown graphically in the second screenshot above, anyone near the right hand side of the chart is a relatively good putter and anyone in the upper half of the graph has a relatively good long game. The ideal location on the chart for a golfer is the upper right quadrant, where the two shaded regions above overlap. This signifies golfers with relatively good strokes gained values in both categories. One such golfer is the highlighted Rickie Fowler, who has a great value for putting in particular.

Some notes on this great new chart.
  1. It is similar to the Field DraftKings Dollars per Point chart previously described here. However, this chart has two average lines instead of the one average line in the DFS chart.
  2. The horizontal yellow line in the middle of the chart is the field average for strokes gained tee to green. The vertical blue line is the field average for strokes gained putting. These lines make it easy to identify the golfers with the best and worst strokes gained in each category at a glance.
  3. These average values for strokes gained tee to green and strokes gained putting are shown above the chart, as can be seen in the screenshots above. You can also hover over the lines to examine the values in the hover text. On each line, one co-ordinate (the average) will remain constant as you move along the line in question.
  4. Like the DraftKings chart mentioned above, this is also zoomable. Please click on the link in the first note above for a description of how this works.
  5. Like other strokes gained features on the site, this chart is only available for the US PGA Tour. Strokes gained are not available on the European Tour.

This great new strokes gained chart chart brings the total number of charts on the site to 486. Only subscribers can view this new chart, so sign up today and reap the full benefits of Golf Predictor, the premium professional golf statistics site.

2017 - Week 34 Predictions/Statistics Online

The predictions and statistics for this week, the Made in Denmark (European PGA Tour) and The Northern Trust (US PGA Tour), are now available on Golf Predictor. It's the first week of the lucrative FedEx Cup play-offs on the US PGA Tour and once again, there is an impressive line up for the re-branded event. Sergio Garcia is the only top ten player in the world not teeing it up at Glen Oaks Club. That doesn't leave much top talent for the European Tour event, but Thomas Pieters is back to defend his title in Denmark.

Sunday, 20 August 2017

2017 - Week 33 Winners

Adrian Otaegui (ranked 13th by Golf Predictor) won the Saltire Energy Paul Lawrie Match Play on the European PGA Tour. The 24 year old Spaniard stunned local favourite Marcel Siem with a 2&1 victory in Germany. Despite being three down at the turn and two down with five to play, Otaegui reeled off three late birdies to turn the match around and snatch his first tour title. Our top ranked player, Bradley Dredge, fell at the first hurdle in the restricted field match play event.

Jason Norris (ranked 75th by Golf Predictor) won the Fiji International on the European PGA Tour. The 44 year old Australian won his first tour title with a fairytale victory in the South Pacific. Norris shot a final round 67 to win by four shots and secure the biggest victory of his twenty one year career. In doing so, he overcame two near death experiences, including an horrific accident in which his jaw was broken in fourteen places. He also is battling the yips on the green and almost gave up the game several times, contemplating a career as a forklift driver! Our top ranked player, Scott Hend, finished in tied 24th and we only had eight of the top twenty four plus ties (8/29) in this weak fielded event.

Henrik Stenson (ranked 1st by Golf Predictor) won the Wyndham Championship on the US PGA Tour. The 41 year old Swede won his first title since his sensational 2016 Open Championship victory with an impressive display at Sedgefield Country Club. Stenson finished strongly with four birdies in his last six holes for a one shot winning margin over fellow fast finisher Ollie Schniederjans. Stenson was our top ranked player and in an event where most of the bigger names failed to perform, we had only a disappointing four of the top sixteen  plus ties (4/23) in total. 

Tuesday, 15 August 2017

Spider/Radar Charts added to Golf Predictor

Jordan Spieth's average finish in multiple historical metrics ahead of the 2017 US PGA Championship. Shows him relatively strong in his last five events and relatively weak in similar weather.

Comparing the field rankings for multiple golfers (tee-off group) ahead of the 2017 US PGA Championship. Love in particular doesn't have FR data for many metrics, so he is assigned the large default value for those.

As above, but with Padraig Harrington's data highlighted for extra legibility.

I am pleased to announce the addition of useful new spider (also known as radar and less commonly, star) charts to Golf Predictor. Spider charts are a type of statistical chart that show the difference in multiple parameters visually at a glance and as such, are very useful for comparing certain stats on Golf Predictor. This can be seen in the screenshots above, for the 2017 US PGA Championship. The main components of a spider chart are:
  1. The spokes emanating from the centre of the chart. The spokes are displayed equidistant from each other and there is one spoke per parameter displayed.
  2. The data points are shown on the spokes. The further away the point is from the origin at the centre, the bigger the value is. On Golf Predictor, this means the worse the stat is.
  3. The points (the parameter values that make up the data set) are joined together to form a polygon. The number of sides to the polygon and its shape depends on the number of parameters displayed on the chart and their values.
  4. There may be more than one data set (polygon) displayed on the same chart, e.g. the data for more than one golfer may be displayed with different colour polygons. This is shown in the second screenshot above, where the polygons for the golfers in a tee-off group for the 2017 US PGA Championship are plotted in different colours.
  5. The concentric grid lines on the spider chart are for scale purposes. It is possible to number this scale, but it doesn't look good and was somewhat confusing with the charting library (see below) that was used.

While ideally, a golfer should have the best statistics possible, in the real world, most top golfers will have some mixture of relatively good, so-so and bad stats. A spider chart tells you immediately where a golfer's relative strength and weaknesses are. For example, the first screenshot above, you can see the average finishing position for Jordan Spieth in multiple relevant historical categories. This shows that his recent performances (last five events) have been relatively good as this value is close to the origin. This, of course, is thanks mainly to his win in The Open! You can also see at a glance that his results in similar weather to what was forecasted for Quail Hollow are relatively bad, being furthest from the origin of the chart.

The ideal spider chart for golfer performance (where small values are good) is a polygon with all data points being as close to the origin as possible. Spieth's chart above is not that far off this, except for his similar weather performance. Some notes on these new spider charts:
  1. There has to be at least three data points to draw a spider/radar chart (you can not draw a polygon without at least three points!).
  2. Initially, I wasted a lot of time trying to use the Flot spider charts plug-in (Flot is used for all the other charts on site, bar the box plots), but I was not happy with the features or the documentation. Eventually I found RGraph, which has some attractive and easy to use spider charts, so I switched to them instead.
  3. Zero data points (i.e. missing values) are left off the single polygon spider (i.e. single golfer) charts. This proved to be the best way to handle this situation. The number of omitted zero point categories is printed above the chart. Leaving them in caused readability issues for certain data sets, as did defaulting them to a high number, e.g. 250.
  4. Zero data points are included on the multiple polygon (i.e. multiple golfers) spider charts, as some of the golfers charted may have a value for that parameter. In this situation, the best option was to have the missing values default to a value slightly above the highest value plotted. When this happens, a message is printed above the chart with the default value. 
  5. Despite the above point, some of the polygons (i.e. data for some golfers) on a multiple polygon spider chart may be difficult to read, depending on the values for the golfers chosen. For example, if you chose to compare stats for someone like Rory McIlroy and someone with poor or no stats, McIlroy's polygon will be hard to read, due to having to plot very good and very bad stats on the same chart. The only workarounds for this are to omit the golfer(s) with poor/no stats from the comparison or compare the stats for similar level golfers (this obviously is not an option if you are comparing a tee-off group!).
  6. Similar to above, a polygon on a spider chart with one or two bad values may be hard to read if all other values are good values. For example, the field ranks stats for Jordan Spieth ahead of the 2017 US PGA Championship are unbelievable, except for his tournament history rank (and his cut streak rank to a much lesser extent). This makes his field rank chart somewhat difficult to read.
  7. On multiple polygon (i.e. multiple golfers) spider charts, you can click on the golfer names in the legend (key) to highlight the values for that golfer. That is very useful for charts with data for more than one golfer, especially where the data overlaps considerably. This is shown in the third screenshot above, where the polygon for Padraig Harrington in the tee-off group for the 2017 US PGA Championship has been highlighted.
  8. The number of polygons (i.e. golfers) on a spider chart is limited to a maximum of four for legibility reasons. However, any more than two can be difficult to read,  but as mentioned above, you can highlight a polygon to see the data for a golfer more clearly.
  9. Also for legibility reasons, polygons on multiple polygon spider charts are not filled in, while they are on single polygon charts.
  10. It was not possible to show the data point values on the chart. However, you can hover over a point to see its value, as shown in the first two screenshots above.
  11. The chart scales automatically, based on the biggest value to display. They may mean that a spider chart for a golfer with all good values may look similar to a chart for a golfer with all bad values. Clicking on a data point will indicate whether the values or all good or bad.
  12. Some of the new spider charts have average values displayed above the chart, where this is useful, e.g. the overall average on the early/mid/late season chart (see below).
  13. I have added a new icon for spider charts. At the very small size (14x14 pixels), it was difficult to create one that didn't just look like a blob! 
  14. You may have to reload any page you have opened in the recent past in order to see these new chart links.
  15. The overview table on the Compare Groups page had slightly different columns from its counterpart in the Compare Golfer page. That has been corrected and the same region performance has been added to the table on the Compare Groups page instead of the world ranking (this is available by choosing the last option in the 'Stats to Compare' dropdown list.
  16. Only subscribers can see the great new multiple polygon charts on the compare pages (see below), so sign up today to see these useful new golfer comparison charts.
There has been a total of six new spider charts added to the pages on the site that show statistical information for a golfer or set of golfers. Specifically, the spider charts have been added to the following pages:
  1. Prediction Data page: two single polygon (i.e. single golfer) spider charts; one for field ranks and one for historical performance (e.g. same course, season, last five events etc.) for each golfer in the field. These two new charts are accessible from the General panel.
  2. Golfer Data page: one single polygon spider chart for regular/major/WGC/FedEx average result in each golfer's career.
  3. Season Segment Data page: one single polygon spider chart for early/mid/late season performance for each golfer.
  4. Compare Golfer/Compare Groups page: one multiple polygon (i.e. multiple golfers) spider chart for the historical performance (e.g. same course, season, last five events etc.) of the chosen golfers/tee-off group.
  5.  Compare Field Ranks/Compare Groups page: one multiple polygon spider chart for the field ranks of the chosen golfers/tee-off group (see last two screenshots above).
This brings the total number of charts on the site to 485. I trust you will find these new spider charts useful as a graphical representation of (multiple) golfer performance in certain key metrics. Just another way to make Golf Predictor even better!

    2017 - Week 29 Winners

    Jordan Spieth (ranked 3rd by Golf Predictor) won The Open Championship on the European/US PGA Tour. The young American won his third major with an amazing finish at Royal Birkdale. Despite leading by three overnight, Spieth started poorly, relinquishing his lead and even ending up among a group of trucks after taking an unplayable on the thirteenth. Having somehow escaped with a bogey on that hole, Spieth put on the afterburners and covered the next four holes in five under par. That allowed him to keep his three shot margin at the end and complete the third leg of the career grand slam at the ripe old age of 23! Our top ranked player, Dustin Johnson, finished poorly on Sunday for tied 54th and we had eight of the top fourteen plus ties (8/19) in the wind affected tournament. 

    Grayson Murray (ranked 5th by Golf Predictor) won the Barbasol Championship on the US PGA Tour. The 23 year old American won his maiden tour title by a single shot in sweltering Alabama. Murray became the latest first time winner (the eleventh this season) by letting his clubs do the talking, rather than his controversial Twitter account!! Despite his well documented issues with anxiety, Murray showed great composure down the stretch to take the lead on the sixteenth and par in for the victory. Indeed, it took a ballsy par putt on the last o seal the win. Our top ranked player, Daniel Summerhays, finished in 63rd and we had twelve of the top eighteen plus ties (12/26) in total in this second tier event.

    2017 - Week 28 Winners

    Rafa Cabrera Bello (ranked 11th by Golf Predictor) won the Aberdeen Asset Management Scottish Open on the European PGA Tour. The 33 year old Spaniard finally won his third tour title with an impressive final day performance in Scotland. Cabrera Bello closed with a course record 64 (-8) and after Callum Shinkwin took four to get down from about 10 yards over the final green, the duo finished level on -13. Shinkwin played the par five eighteenth in a similar manner again and after the Spaniard hit a great second shot to about twelve feet, it was all but over. Shinkwin still had a chance to prolong the play-off, but left his putt criminally short for the second time. That allowed the happy Cabrera Bello to end his five and a half year wait for another title. Our top ranked player, Henrik Stenson, finished tied 26th and in an event where many of the top players failed to perform in the sometimes difficult conditions, we only had six of the top nineteen plus ties (6/25).   

    Byron DeChambeau (ranked 5th by Golf Predictor) won the John Deere Classic on the US PGA Tour. The 23 year old American became the tenth first time winner on the PGA Tour this season at TPC Deere Run. DeChambeau finished superbly with two birdies for what he believed would be a tie at best. However, after Patrick Rodgers bogeyed the seventeenth and failed to bounce back at the last, the title went to the golfing scientist! Our top ranked player, Daniel Berger fading slightly on the back nine, but finished with two birdies for tied 5th. Overall, we had nine of the top nineteen plus ties (9/24).

There are not many big names teeing it up in West Virginia this week, where the tournament makes a welcome return to the schedule after being cancelled last year due to devastating floods. Meanwhile, here in Ireland, Rory McIlroy is defending the tournament he is hosting at Portstewart. As it is now part of the Rolex Series and just two weeks before The Open Championship, there is a stellar field this year in Co. Derry. Five of the top fifteen in the world will be hoping to get their links game in shape for the big one in two weeks time!

    2017 - Week 26 Winners

    Tommy Fleetwood (ranked 8th by Golf Predictor) won the HNA Open de France on the European PGA Tour. The 26 year old Englishman continued his impressive recent form by winning his third tour title in Paris. Fleetwood finished with an impressive bogey free 66 on the 2018 Ryder Cup venue and although his lead was four shots on the back nine at one point, a strong finish by Peter Uihlein meant he won by just a single shot in the end. Our top ranked player, Alex Noren, finished in tied tenth and we had only seven of the top sixteen plus ties (7/22) on the testing layout.

    Kyle Stanley (ranked 19th by Golf Predictor) won the Quicken Loans National on the US PGA Tour. The 29 year old American won his second tour title in a play-off with Charles Howell III.

    2017 - Week 26 Predictions/Statistics Online

    The predictions and statistics for this week, the HNA Open de France (European PGA Tour) and the Quicken Loans National (US PGA Tour), are now available on Golf Predictor. There aren't many big names at Tiger Woods' tournament this week, including the man himself, who is getting help for his addiction issues. However, Rickie Fowler makes his first appearance since contending at the US Open. The French event sees the European Tour début of rookie sensation John Rahm, thanks no doubt to its updated status as a Rolex Series event and the venue being the host of the next Ryder Cup.


    2017 - Week 25 Winners

    Andres Romero (ranked 147th by Golf Predictor) won the BMW International Open on the European PGA Tour. The 36 year old Argentinian won his second tour title with a birdie burst on the back nine to edge out Sergio Garcia, Thomas Detry and Richard Bland by a single shot. Ten years after his only other victory which was also in Germany, Romero relied on a sponsor's invite after falling to 837th in the world rankings. Indeed, he is the lowest ranked golfer ever to win on Golf Predictor (147) and he did it with an impressive blemish free final round 65 (-7). On a tightly packed leaderboard, Romero posted his score and after Garcia missed a tiddler on sixteen and Bland bogeyed seventeen, both needed an eagle on the last to tie. It wasn't to be and a grateful Romero returned unexpectedly to the winner's circle. Garcia was our top ranked player and we had ten of the top twenty plus ties (10/25)

    Jordan Spieth (ranked 3rd by Golf Predictor) won the Travelers Championship on the US PGA Tour. The 23 year old American became the second youngest after Tiger Woods to register ten wins on the PGA Tour season in his first appearance at TPC River Highlands. Despite a good start, Spieth didn't play well on Sunday and was lucky not to find the water three times on the closing nine holes. He was caught by Daniel Berger, who played well on Sunday to come from five shots back to force a play-off. However, Spieth was not to be denied and he holed out spectacularly from the bunker on the first extra hole to get over the line. Our top ranked player, Rory McIlroy, finished strongly for tied 17th, despite swapping putters several times during the week! Overall, we had eleven of the top seventeen plus ties (11/25) in total.
