In the era of modern technology, advanced fitness regimens and long driving competitions, there has been a growing sentiment towards golf favoring the ‘bomb-n-gouge’ style of play. However, we still see many shorter-hitting golfers like Zach Johnson who are successful in the game. Most of the clients on Tour I work with have questioned the advantages that power can have on Tour versus hitting the ball the more accurately. As a competitive amateur golfer myself, it was one of the first things I investigated from a statistical standpoint.

Part of the issue deals with the main metric designed to determine driving skill on Tour, called ‘Total Driving.” Total Driving utilizes a very simple formula by adding the rankings of a player’s Driving Distance and Fairway Percentage together. The lower the combined ranking, the better the golfer will rank in Total Driving. But it’s metrics like Total Driving that have only produced more questions than answers for golfers.

The main issue with the Total Driving metric is that it is flawed from a statistical standpoint and it is a very incomplete formula. From a pure statistical standpoint, the addition of taking the rankings and adding them together is a bad idea in general. Theoretically, a golfer on Tour could hit nothing but 4-irons off the tee and would likely lead the Tour in percentage of Fairways Hit. But, they would also likely be dead last in driving distance. And using the Total Driving formula of adding up the rankings would misrepresent how well the golfer hits the ball off the tee.

In that example, the golf would rank No. 1 in Fairway Percentage and No. 191 in Driving Distance. That would combine for 192 Total Driving points, leaving this particular golfer ranked 100^th out of 192 golfers on Tour in Total Driving. However, the reality is that if a Tour golfer hit nothing but 4 irons off the tee, they would almost be guaranteed to be the least effective driver of the ball on Tour, if not in the history of the Tour.

And therein lies part of another issue with Total Driving — it assumes that driving distance is just as important as fairway percentage. When examining Driving Distance and Fairway Percentage to par-4 and par-5 scoring averages, the data shows that they are not of equal importance.

Not wanting to stop at just driving distance and fairway percentage, I examined other metrics as well. The one metric that showed some statistical influence to par-4 and par-5 scoring averages is called “Average Distance to the Edge of the Fairway.” This metric is measured on shots by a Tour player when they miss the fairway.

It’s easy to understand why combining Driving Distance, Fairway Percentage and Distance To the Edge of the Fairway can show a strong correlation to par-4 and par-5 scoring average. Distance helps measure power, fairway percentage helps measure accuracy and distance to the edge of the fairway helps measure precision. Now the question becomes putting it in a formula to best represent its effect on Tour players and then examine the results.

Eventually I came up with my own metric that I call “Driving Effectiveness.” It combines the metrics of Driving Distance, Fairway Percentage and Average Distance To the Edge of the Fairway. However, it utilizes the actual measurements instead of using the rankings. Furthermore, it weighs those metrics differently to better represent its typical impact on Tour golfers on par-4s and par-5s. Without giving the formula away, I will say that in the end that Driving Distance and Distance to the Edge of the Fairway have a larger impact on a golfer’s score than fairway percentage. But, do not let that fool you into believing that hitting fairways is unimportant.

Here is a table showing the top-10 and bottom-10 players in Driving Effectiveness and the Total Driving metric.

Top-10 in Driving Effectiveness

Bottom 10 in Driving Effectiveness

While there are some similarities between the rankings of the two metrics, there are plenty of players who are not accurately depicted in Total Driving. Here’s a look at the top-10 players who had the largest improvement in Driving Effectiveness ranking from the Total Driving metric.

Here are the players with the largest decline in Driving Effectiveness ranking from the Total Driving metric.

In golfers who had a much better Driving Effectiveness ranking, we see that favoring shorter hitters a little. Conversely, with the golfers with a worse Driving Effectiveness ranking, that has a small bias towards longer hitters. The reason being has to do with the Average Distance To The Edge of the Fairway metric.

However, the bias is somewhat small. I believe the reason for that is regardless of their length off the tee, Tour players do not typically see a sizeable difference in where they rank on Tour between fairway percentage and Average Distance to the Edge of the Fairway.

For example, KJ Choi saw the largest difference in Driving Effectiveness (67^th) versus Total Driving (128^th). Choi was ranked 54^th in fairway percentage, hitting 64.08 percent of his fairways. But, Choi was also 2^nd in Average Distance to the Edge of the Fairway, hitting it 18.7 feet from the edge on average. Thus, Choi was more effective than Total Driving indicates because when he did miss the fairway, he did not miss by much.

I think that amateurs can apply the general principles of Driving Effectiveness in their own game as well. If they are looking to become more effective off the tee, the ways to make the largest improvements would be to increase their driving distance (power) and their Distance to the Edge of the Fairway (precision). If they are looking at swing changes or a new driver in order to increase distance, they should focus more on how that may possibly affect their Average Distance To The Edge of the Fairway.

However, if they gain power but lose too much precision they may end up being less effective in the long run. And if they do not believe they can gain any power, they should probably focus their efforts on Fairway percentage (accuracy) and Distance To The Edge of the Fairway (precision) in order become more effective off the tee.

The Wedge Guy: My top 5 practice tips

Published

Sep 22, 2023

Terry Koehler

While there are many golfers who barely know where the practice (I don’t like calling it a “driving”) range is located, there are many who find it a place of adventure, discovery and fun. I’m in the latter group, which could be accented by the fact that I make my living in this industry. But then, I’ve always been a “ball beater,” since I was a kid, but now I approach my practice sessions with more purpose and excitement. There’s no question that practice is the key to improvement in anything, so today’s topic is on making practice as much fun as playing.

As long as I can remember, I’ve loved the range, and always embrace the challenge of learning new ways to make a golf ball do what I would like it to do. So, today I’m sharing my “top 5” tips for making practice fun and productive.

Have a mission/goal/objective. Whether it is a practice range session or practice time on the course, make sure you have a clearly defined objective…how else will you know how you’re doing? It might be to work on iron trajectory, or finding out why you’ve developed a push with your driver. Could be to learn how to hit a little softer lob shot or a knockdown pitch. But practice with a purpose …always.
Don’t just “do”…observe. There are two elements of learning something new. The first is to figure out what it is you need to change. Then you work toward that solution. If your practice session is to address that push with the driver, hit a few shots to start out, and rather than try to fix it, make those first few your “lab rats”. Focus on what your swing is doing. Do you feel anything different? Check your alignment carefully, and your ball position. After each shot, step away and process what you think you felt during the swing.
Make it real. To just rake ball after ball in front of you and pound away is marginally valuable at best. To make practice productive, step away from your hitting station after each shot, rake another ball to the hitting area, then approach the shot as if it was a real one on the course. Pick a target line from behind the ball, meticulously step into your set-up position, take your grip, process your one swing thought and hit it. Then evaluate how you did, based on the shot result and how it felt.
Challenge yourself. One of my favorite on-course practice games is to spend a few minutes around each green after I’ve played the hole, tossing three balls into various positions in an area off the green. I don’t let myself go to the next tee until I put all three within three feet of the hole. If I don’t, I toss them to another area and do it again. You can do the same thing on the range. Define a challenge and a limited number of shots to achieve it.
Don’t get in a groove. I was privileged enough to watch Harvey Penick give Tom Kite a golf lesson one day, and was struck by the fact that he would not let Tom hit more than five to six shots in a row with the same club. Tom would hit a few 5-irons, and Mr. Penick would say, “hit the 8”, then “hit the driver.” He changed it up so that Tom would not just find a groove. That paved the way for real learning, Mr. Penick told me.

My “bonus” tip addresses the difference between practicing on the course and keeping a real score. Don’t do both. A practice session is just that. On-course practice is hugely beneficial, and it’s best done by yourself, and at a casual pace. Playing three or four holes in an hour or so, taking time to hit real shots into and around the greens, will do more for your scoring skills than the same amount of range time.

So there you have my five practice tips. I’m sure I could come up with more, but then we always have more time, right?

Vincenzi: Fortinet Championship First Round Leader picks

Matt Vincenzi

The PGA Tour begins its fall season with a trip to Wine Country as the world of golf patiently awaits the 2023 Ryder Cup which is just a few weeks away. Silverado is a course where plenty of players with varying skill sets can compete, but strong West Coast history tends to be a major factor.

In the past four editions of the Fortinet Championship, there have been six first-round leaders or co-leaders. Of the six, three have started their rounds in the morning wave, and three started in the afternoon. The leading scores have all been between 63 and 65.

As of now, the winds look to be very docile, with speeds of 4-7 MPH throughout the day. I don’t see either the AM or PM wave as having a major advantage.

2023 Fortinet Championship First-Round Leader Picks

Zac Blair +9000 (FanDuel)

First-Round Tee Time: 1.22 p.m PT

A big theme for me this week is targeting players who have had success at both Silverado and the West Coast in general. Blair finished 22nd here last year, and also finished 4th back in 2019. That year, he shot 66 in rounds two and three, showing his ability to go low on this track.

In 2022, Blair gained 3.8 strokes putting and in 2019, he gained 8.6. The 33-year-old seemingly has these greens figured out.

C.T. Pan +9000 (FanDuel)

First-Round Tee Time: 8.23 a.m PT

At the end of the 2023 season, C.T. Pan showed flashes of what made him a good player prior to his injury struggles early in the year. He finished 4th at the AT&T Byron Nelson in May, and 3rd at the RBC Canadian Open in June. He also finished 6th at Silverado back in 2021, gaining 4.5 strokes on approach and 6.6 strokes putting.

A few weeks off may have given Pan a chance to reset and focus on the upcoming fall swing, where I believe he’ll play some good golf.

Joel Dahmen +110000 (FanDuel)

First-Round Tee Time: 7:28 a.m PT

After becoming a well-known name in golf due to his affable presence in Netflix’ “Full Swing” documentary, Dahmen had what can only be considered a disappointment of a 2023 season. I believe he’s a better player than he showed last year and is a good candidate for a bounce back fall and 2024.

Dahmen finished in a tie for 10th at the Barracuda Championship in late July, and the course is similar in agronomy and location to what he’ll see this week in Napa. He has some strong history on the West Coast including top-ten finishes at Riviera (5th, 2020), Pebble Beach (6th, 2022), Sherwood (8th, 2020), TPC Summerlin (9th, 2019) and Torrey Pines (9th, 2019).

James Hahn +125000 (Caesars)

First-Round Tee Time: 1:55 p.m PT

James Hahn absolutely loves golf on the West Coast. He’s won at Riviera and has also shown some course form with a 9th place finish at Silverado back in 2020. That week, Hahn gained 4.7 strokes putting, demonstrating his comfort level on these POA putting surfaces.

He finished T6 at the Barracuda back in July, and there’s no doubt that a return to California will be welcome for the 41-year-old.

Peter Malnati +125000 (BetRivers)

First-Round Tee Time: 12.27 p.m PT

Peter Malnati excels at putting on the West Coast. He ranks 3rd in the field in Strokes Gained: Putting on POA and has shown in the past he’s capable of going extremely low on any given round due to his ability to catch a hot putter.

His course history isn’t spectacular, but he’s played well enough at Silverado. In his past seven trips to the course, he’s finished in the top-35 four times.

Harry Higgs +150000 (BetRivers)

First-Round Tee Time: 1.55 p.m PT

In what is seemingly becoming a theme in this week’s First-Round Leader column, Harry Higgs is a player that really fell out of form in 2023, but a reset and a trip to a course he’s had success at in the past may spark a resurgence.

Higgs finished 2nd at Silverado in 2020 and wasn’t in particularly great form then either. Success hasn’t come in abundance for the 31-year-old, but three of his top-10 finishes on Tour have come in this area of the country.

Higgs shot an impressive 62 here in round two in 2020, which would certainly be enough to capture the first-round lead this year.

Vincenzi’s Fortinet Championship betting preview: California native ready for breakthrough win in Napa

Published

2 weeks ago

Sep 11, 2023

Matt Vincenzi

After a three-week break, the 2022-23 PGA TOUR season kicks off in Napa Valley at the Silverado Resort and Spa to play the Fortinet Championship.

Prior to 2021, the event was called the Safeway Open, but the tournament sponsor changed to Fortinet with contract that will last for three more seasons. Although the name has changed multiple times, Silverado’s North Course has been featured on the PGA TOUR since 1968.

The course is a par 72, measuring at 7,166 yards. Silverado features Poa annua greens that can be tricky, especially as the surface becomes bumpier in the afternoon. The tree-lined fairways aren’t easy to hit, but the rough shouldn’t be exceedingly penal. Shorter hitters are in play on this relatively short course, and accuracy will be at a premium.

There will be a re-routing at Silverado for this year’s Fortinet Championship. Ten holes will be played in a different order. Holes 1-7 and 18 will remain as in year’s past. The new finishing stretch – No. 14 (par 4), No. 15 (par 5), No. 16 (par 4), No. 17 (par 3) and No. 18 (par 5). The new 17th was previously the 11th, which is the signature hole on the course.

The field will consist of 155 players. Being the swing season, the field for this event is usually relatively weak. However, there are some intriguing names in the field including Justin Thomas, Webb Simpson, Sahith Theegala, Joel Dahmen, and Kevin Kisner.

Past Winners

2022: Max Homa (-22)
2021: Max Homa (-19)
2020: Stewart Cink (-21)
2019: Cameron Champ (-17)
2018: Kevin Tway (-14)
2017: Brendan Steele -15
2016: Brendan Steele -18

Let’s take a look at several key metrics for Silverado to determine which golfers boast top marks in each category over their last 24 rounds.

Strokes Gained: Approach

Historically, one of the North Course’s defenses will be tightly tucked pin placement, so effective shot-shaping and a higher ball flight may be an advantage this week. In order to find success, players need to hit the correct level of the sloping Poa Annua greens.

Strokes Gained: Approach past 24 rounds:

Chez Reavie (+24.7)
Sam Ryder (+20.0)
Mark Hubbard (+17.8)
Kevin Streelman (+18.3)
Doug Ghim (+17.1)

Good Drives Gained

Hitting fairways in regulation at Silverado is more difficult than TOUR average, as players have done so in the past at a rate of only 52.2%. While the rough isn’t extremely long here, controlling spin out of the thick grass is much more difficult than doing so from the fairway. In order to find success, players need to hit the correct level of the sloping Poa annua greens.

In 2021, the top eight players on the leaderboard all had a positive week in “Good Drives Gained. The winner, Max Homa was +3.3 in the category and Mito Pereira, who finished third, was +8.3.

In 2022, 12 of the top 13 players on the leaderboard gained in the category including the winner Max Homa (+6.0) and runner up Danny Willet (5.0).

Good Drives Gained past 24 rounds:

Doug Ghim (+24.4)
Matt NeSmith (+23.8)
Russell Knox (+20.6)
Brice Garnett (+19.9)
Ryan Armour (+19.8)

Par 4: 400-450

There are six par 4’s at Silverado that are between 400 and 450-yards. It will be important to target players who excel at playing these holes. With the par 5s being fairly short and reachable, the par 4 scoring may prove to be the bigger difference-maker.

Par 4: 400-450 past 24 rounds:

Beau Hossler (+14.7)
Max Homa (+12.4)
Garrick Higgo (+8.5)
Justin Suh (+8.3)
Stephan Jaeger (+8.2)

Birdie or Better: Gained

With scores at Silverado potentially approaching the 20 under par range, making plenty of birdies will be a requirement in order to contend this week.

Birdie or Better: Gained in past 24 rounds:

Nick Hardy (+15.3)
Scott Piercy (+15.2)
Ryan Gerard (+14.9)
Max Homa (+14.0)
Peter Kuest (+13.5)

Strokes Gained: Putting (Poa Annua)

Poa annua greens on the West Coast can be quite difficult for golfers to adjust to if they don’t have much experience on the surface.

Prior to the 2019 Safeway Open, Phil Mickelson talked about how the type of putting surface is a major factor:

“I think a lot of guys struggle with the Poa annua greens, which is a grass that I grew up playing, so I’m very comfortable on the greens. When you grow up and spend most of your time back east in Florida on the Bermuda, this is a very awkward surface to putt on. The color looks different — it’s hard to sometimes read. But when you’re used to it, I don’t know of much better surfaces than these right here.”

This week it is important to look for the golfers who historically excel on Poa annua.

Total Strokes Gained in category in past 24 rounds:

Kevin Kisner (+27.7)
Max Homa (+21.2)
Peter Malnati (+20.5)
Justin Suh (+18.5)
Mackenzie Hughes (+16.0)

Statistical Model

Below, I’ve reported overall model rankings using a combination of the five key statistical categories previously discussed.

These rankings are comprised of SG: APP (25%), Good Drives Gained: (25%), Birdie or Better (20%), Par 4: 400-450 (15%), SG: Putting (Poa annua) (15%).

Max Homa (+750)
Doug Ghim (+5000)
Andrew Putnam (+4000)
Chez Reavie (+4500)
Kevin Streelman (+5500)
Mark Hubbard (+5000)
Sam Ryder (+7000)
Brendon Todd (+3500)
Akshay Bhatia (+6000)
Cameron Davis (+2200)

2023 Fortinet Championship Picks

Sahith Theegala +2000 (DraftKings):

Sahith Theegala is yet to break out for his maiden PGA Tour victory but is a great candidate for a player who can have a strong fall and take advantage of some weaker fields. The 26-year-old ended his season on a positive note, finishing 13th at the FedEx St. Jude and 15th at the BMW Championship.

I’ve long believed that Theegala’s first win would come on the West Coast. He grew up in California and was a three-time All-American at Pepperdine University, where he became the fifth player to win the Jack Nicklaus Award, Haskins Award and Ben Hogan award all in the same year (2020). Sahith made his PGA Tour debut at Silverado in 2020, where he finished in a tie for 14th. Last year, he finished 6th at the Fortinet Championship.

Theegala is very comfortable playing in California. That is perhaps most noticeable on the putting surface where he gains an average of +0.44 strokes on the field per event on POA, which is more than four times what he gains on Bermudagrass or Bentgrass. The POA greens at Silverado can get especially difficult late in the day, which is a reason why players with a background on them have had so much success at the course. In the past seven years of the event, five winners have come from California.

Theegala is pricey this week and is as close to the top of the odds board as I can remember him being, but that’s the nature of the PGA Tour fall season. It’s hard to find a spot on the schedule that Sahith will have a better chance at winning than this one.

Justin Suh +5000 (PointsBet):

Consistency has been an issue early in the career of Justin Suh, but he’s shown flashes in 2023 of what made him such a highly regarded prospect to begin with. After a few top-10 finishes at the PLAYERS Championship and the Honda Classic, Suh ended the season on a bit of a sour note, failing to finish better than 34th in his last five starts of the season.

Despite the struggles, I’m optimistic about Suh as we begin the fall swing. The 26-year-old made the trip to Crans-Montana, Valais, Switzerland to play in the Omega European Masters, and finished 24th in a decent field. More encouraging than the finish was how Suh hit the ball. He gained 5.24 strokes on approach and hit plenty of fairways.

The 2018 Pac-12 Player of the Year grew up on California golf courses. Suh was a highly decorated amateur golfer with plenty of wins on the West Coast prior to attending USC, where he was one of the best players in the country.

When he’s on, Suh is one of the best putters on Tour, and he should comfortable playing in his home state in search of his first PGA Tour victory.

Akshay Bhatia +5500 (DraftKings):

Akshay Bhatia is still just 21 years old and one of the most tantalizing prospects in the world of golf. The smooth-swinging lefty was able to obtain his first PGA Tour victory at the Barracuda Championship at Tahoe Mountain Club in Truckee, California just a few months ago. The course is just a few hours ride from Silverado and the conditions and course should be very similar.

Bhatia will have no issue making birdies in bunches at Silverado, and the rough shouldn’t be exceedingly penal if he gets loose with his driver.

Bhatia made his debut at Silverado in 2020 at just 18 years old and managed to finish 9th. Since then, he’s gained a great deal of confidence and has refined his game as a professional.

Akshay got engaged this week. He can celebrate with a victory this week at the Fortinet.

Sam Ryder +8000 (FanDuel):

Statistically, Sam Ryder jumps off the page this week. In his past four measured starts, he’s gained 4.2, 5.4, 5.2 and 5.7 strokes on approach and is completely dialed in with his irons. Despite the numbers, he hasn’t managed to crack the top-30 on the leaderboard in that stretch but this is a field that is much weaker than he faced at the end of last season.

In addition to the recent stats, Ryder played some good golf on the West Coast last year. Most notably, he finished 4th at Torrey Pines in a loaded field and also finished 20th at both the Waste Managment Phoenix Open and the Genesis Invitational.

If Ryder continues with his hot approach play, he should be able to contend at Silverado this week.
