The stats behind Phil Mickelson’s switch to Andrew Getson

Published

on

It was big news in the golf instruction industry when Phil Mickelson decided to part ways with long-time coach Butch Harmon and hired Andrew Getson to take over. Mickelson was not exactly performing poorly by normal Tour standards, as he made 16 out of 19 cuts and finished 48th in Adjusted Scoring Average for the season. But Mickelson’s seasons are judged by victories and performance in the majors, and Phil may have felt that there was a need to change after two winless seasons.

As a golf statistician, I wanted to look at Phil’s performance from this past season along with his performance in his most recent “big” season, 2013, when he won the British Open, finished 12th in Adjusted Scoring Average and earned nearly $5.5 million. I would assume that performance in 2013 is something that Phil wants to get back to.

While the two most important metrics in the chart above are Par-4 Scoring Average and Bogey Rate, it’s always good to look at all of the metrics to help paint a more clear picture of what is going on with the golfer’s game. In Phil’s case, the drop-off in Par-4 Scoring Average and Bogey rate is dramatic and needs to be addressed.

For most of Phil’s career, he’s been a great iron player and a weak driver of the ball with fantastic ability to get up-and-down. So I would immediately wonder how his typical game is playing a factor in this decline in performance. The silver lining in all of this, however, is that he can still make a lot of birdies.

DRIVING DATA

Mickelson_instructor_switch_2

The driving metrics are interesting because the only sub-category of metrics that Phil was better in this season was driving distance. He ended up 74th in Driving Effectiveness, however, the main reason being is that Mickelson ranked third in terms of driving difficulty schedule. I have found it easy for a Tour player to fall in the trap of thinking he is not performing well in a certain area of the game when the reality is that the difficulty has amplified. He can actually be doing well in terms of his performance versus the rest of the field.

For instance, TPC Summerlin is one of the most difficult courses to hit short-game shots (inside 30 yards) on the entire Tour schedule. Thus, I remind my clients to not get too down on themselves if they are not hitting their short-game shots close. The make percentage on the greens is higher, too, so they can save par anyway. This may have been a problem for Phil. He may have felt that his driving performance was not improving, but in reality the conditions and course designs were more difficult than they have been in the past.

APPROACH SHOT DATA

Mickelson_instructor_switch_3

Iron play has usually been Phil’s greatest strength, and it was on display in the 2013 season. It is becoming a weakness now, however. The drop-off is larger from 100-150 yards, but the smart move would be to work on his performance from 175-225 yards, because that will have a bigger influence on lowering his scores.

And just so we can make sure that his drop in iron play is not due to missing more fairways, here is his performance from the fairway versus the rough.

Mickelson_instructor_switch_4-1

Also, there was a new metric that I started to record this year: Scoring Average on Dogleg Left Holes versus Dogleg Right Holes versus Straight-Away Par-4’s (adjusted based on hole difficulty).

Mickelson_instructor_switch_5-1

I find these metrics interesting. Phil’s overall driving has improved, but while he hits a ball that curves from right-to-left his performance on the DogLeg left Par-4’s is much worse.

While I am in the initial stages of studying the doglegs versus the straight-away par-4’s, the initial analysis shows that more of the very long Par-4’s (460+ yards) tend to be DogLeg left holes. With Phil’s performance from 150-225 yards regressing, that may explain why he has struggled on the dogleg left par-4’s this past season. And that regression on longer approach shots would help explain his struggles on the par-3’s, as par-3 play is one part iron play, one part short game and one part putting outside 20-feet.

SHORT GAME DATA

Mickelson_instructor_switch_6

Phil’s Total Short Game performance has regressed mainly because he has regressed most from the most important distance, 10-20 yards. This would play a bigger factor in his struggles on the Par-3’s and his ability to avoid bogeys on the Par-4’s. Essentially, he is not hitting as many GIR because of his iron play, and cannot hit his short game shots close enough to put himself in good position to save par.

PUTTING DATA

Mickelson_Instructor_Switch_7

Phil still putted well in 2015, so I don’t think that is a big issue. In fact, the history on Tour shows he was not likely to sustain his putting from outside 15-feet regardless of what he did after the 2013 season.

I expect Phil to continue to work on his driving, which is not necessarily a bad idea. However, he made nearly $5.5 million and won a major while driving the ball poorly in 2013. I think the better move is to focus on getting his iron play back, particularly from 150-225 yards, and see if they can regain his old short game form.

    The best thing Phil needs to do is to get rid of the old timey putter and go to Scotty Cameron and let Scotty make a putter that is right for him.

    Great article. Another good read from Rich! Really interested to see the findings on dog legs. I’m thinking that you may see better scoring with players that shape the ball against the shape of the hole. Ie misses will more likely be on the ‘far side’ of the dog leg!

    I enjoyed the analysis! It is very interesting to see stuff like this and number do not lie. I wonder how much is rheumatoid arthritis has played into his ability to be able to practice and play as often as he would like? I would assume that someone with his condition has good and bad days.

    Very interesting but with one error which I wish all columnists at Golfwrx would get right. It is The Open NOT The British Open.

      HI Bubba. With respect, please check out the PGA Tour Schedule for 2015/16… http://www.pgatour.com/news/2015/07/30/schedule-release.html
      You will see that the PGA tour even call it “The Open Championship”. Calling it the British Open would be like calling The Masters The American Masters as there are various Masters tournements around the world. I know I’m being a golf pedant. 🙂

        Isn’t calling it the British Open more analogous to calling the men’s open tournament run by the USGA the “U.S. Open”?

    RH- Well done. Interesting analysis. Let us know if Phil sees this and gives you any feedback.

    Phil won $5.5 million in 2013 based largely on wins at the Scottish Open, Open Championship and a second place finish in the US Open. The keys to his fine play in those three tournaments were Phil’s use of the mini driver off the tee, and fantastic wedge play.

    The mini driver and excellent wedge play are really all you need to know about the keys to Phil’s ability to win another major.

      Greg V –

      I don’t have the data for those specific events because 2 are majors and the other is the Scottish Open which does not count towards those $5.5 million in earnings (PGA Tour only). You will generally find that in the Majors, shots from 175-250 yards matter most if you want to segment them. Driving is typically more important at the US Open than at the British Open. But, wedge play rarely makes a substantial impact. I think from 2013 we can see how elite Phil’s iron play was and I would imagine that it carried over to the British, Scottish and US Opens. In Phil’s years using the mini-driver, his driving still wasn’t very effective.

    While I understand why Phil had to change instructors, he has to accept the fact that he’s not the young gun as he once was in the late 90s and early 2000s (Jordan, Rory, Jason and Dustin have that torch now) and his career is on the downswing. He’ll have to accept 10 ten finishes at best while he is old enough for the Champions tour.

    I do think we’ve all been waiting for the other shoe to drop with the RA and it’s effect on his game. And of course his age can’t be overlooked, although based on his driving distance he’s still plenty competitive athletically. Really though, looking at those stats, doesn’t just look like someone who hasn’t been playing as much golf? It really all looks like just an overall decline in sharpness due to fewer reps in the practice area. It’s always seemed to me that his golf game kept his interest much longer than most of the top money winners in the era of instant-millionaire golf, but it’s only natural to slow down a bit when life is frankly pretty damn good by all appearances. And with that much money on the table, the young guys are now grinding harder than ever to get there.

Vincenzi’s 2024 Zurich Classic of New Orleans betting preview

Published

on

The PGA TOUR heads to New Orleans to play the 2023 Zurich Classic of New Orleans. In a welcome change from the usual stroke play, the Zurich Classic is a team event. On Thursday and Saturday, the teams play best ball, and on Friday and Sunday the teams play alternate shot.

TPC Louisiana is a par 72 that measures 7,425 yards. The course features some short par 4s and plenty of water and bunkers, which makes for a lot of exciting risk/reward scenarios for competitors. Pete Dye designed the course in 2004 specifically for the Zurich Classic, although the event didn’t make its debut until 2007 because of Hurricane Katrina.

Coming off of the Masters and a signature event in consecutive weeks, the field this week is a step down, and understandably so. Many of the world’s top players will be using this time to rest after a busy stretch.

However, there are some interesting teams this season with some stars making surprise appearances in the team event. Some notable teams include Patrick Cantlay and Xander Schauffele, Rory McIlroy and Shane Lowry, Collin Morikawa and Kurt Kitayama, Will Zalatoris and Sahith Theegala as well as a few Canadian teams, Nick Taylor and Adam Hadwin and Taylor Pendrith and Corey Conners.

Past Winners at TPC Louisiana

  • 2023: Riley/Hardy (-30)
  • 2022: Cantlay/Schauffele (-29)
  • 2021: Leishman/Smith (-20)
  • 2019: Palmer/Rahm (-26)
  • 2018: Horschel/Piercy (-22)
  • 2017: Blixt/Smith (-27)

2024 Zurich Classic of New Orleans Picks

Tom Hoge/Maverick McNealy +2500 (DraftKings)

Tom Hoge is coming off of a solid T18 finish at the RBC Heritage and finished T13 at last year’s Zurich Classic alongside Harris English.

This season, Hoge is having one of his best years on Tour in terms of Strokes Gained: Approach. In his last 24 rounds, the only player to top him on the category is Scottie Scheffler. Hoge has been solid on Pete Dye designs, ranking 28th in the field over his past 36 rounds.

McNealy is also having a solid season. He’s finished T6 at the Waste Management Phoenix Open and T9 at the PLAYERS Championship. He recently started working with world renowned swing coach, Butch Harmon, and its seemingly paid dividends in 2024.

Keith Mitchell/Joel Dahmen +4000 (DraftKings)

Keith Mitchell is having a fantastic season, finishing in the top-20 of five of his past seven starts on Tour. Most recently, Mitchell finished T14 at the Valero Texas Open and gained a whopping 6.0 strokes off the tee. He finished 6th at last year’s Zurich Classic.

Joel Dahmen is having a resurgent year and has been dialed in with his irons. He also has a T11 finish at the PLAYERS Championship at TPC Sawgrass which is another Pete Dye track. With Mitchell’s length and Dahmen’s ability to put it close with his short irons, the Mitchell/Dahmen combination will be dangerous this week.

Taylor Moore/Matt NeSmith +6500 (DraftKings)

Taylor Moore has quickly developed into one of the more consistent players on Tour. He’s finished in the top-20 in three of his past four starts, including a very impressive showing at The Masters, finishing T20. He’s also finished T4 at this event in consecutive seasons alongside Matt NeSmith.

NeSmith isn’t having a great 2024, but has seemed to elevate his game in this format. He finished T26 at Pete Dye’s TPC Sawgrass, which gives the 30-year-old something to build off of. NeSmith is also a great putter on Bermudagrass, which could help elevate Moore’s ball striking prowess.

Vincenzi’s 2024 LIV Adelaide betting preview: Cam Smith ready for big week down under

Published

on

After having four of the top twelve players on the leaderboard at The Masters, LIV Golf is set for their fifth event of the season: LIV Adelaide. 

For both LIV fans and golf fans in Australia, LIV Adelaide is one of the most anticipated events of the year. With 35,000 people expected to attend each day of the tournament, the Grange Golf Club will be crawling with fans who are passionate about the sport of golf. The 12th hole, better known as “the watering hole”, is sure to have the rowdiest of the fans cheering after a long day of drinking some Leishman Lager.  

The Grange Golf Club is a par-72 that measures 6,946 yards. The course features minimal resistance, as golfers went extremely low last season. In 2023, Talor Gooch shot consecutive rounds of 62 on Thursday and Friday, giving himself a gigantic cushion heading into championship Sunday. Things got tight for a while, but in the end, the Oklahoma State product was able to hold off The Crushers’ Anirban Lahiri for a three-shot victory. 

The Four Aces won the team competition with the Range Goats finishing second.

2024 LIV Adelaide Picks

Cameron Smith +1400 (DraftKings)

When I pulled up the odds for LIV Adelaide, I was more than a little surprised to see multiple golfers listed ahead of Cameron Smith on the betting board. A few starts ago, Cam finished runner-up at LIV Hong Kong, which is a golf course that absolutely suits his eye. Augusta National in another course that Smith could roll out of bed and finish in the top-ten at, and he did so two weeks ago at The Masters, finishing T6.

At Augusta, he gained strokes on the field on approach, off the tee (slightly), and of course, around the green and putting. Smith able to get in the mix at a major championship despite coming into the week feeling under the weather tells me that his game is once again rounding into form.

The Grange Golf Club is another course that undoubtedly suits the Australian. Smith is obviously incredibly comfortable playing in front of the Aussie faithful and has won three Australian PGA Championship’s. The course is very short and will allow Smith to play conservative off the tee, mitigating his most glaring weakness. With birdies available all over the golf course, there’s a chance the event turns into a putting contest, and there’s no one on the planet I’d rather have in one of those than Cam Smith.

Louis Oosthuizen +2200 (DraftKings)

Louis Oosthuizen has simply been one of the best players on LIV in the 2024 seas0n. The South African has finished in the top-10 on the LIV leaderboard in three of his five starts, with his best coming in Jeddah, where he finished T2. Perhaps more impressively, Oosthuizen finished T7 at LIV Miami, which took place at Doral’s “Blue Monster”, an absolutely massive golf course. Given that Louis is on the shorter side in terms of distance off the tee, his ability to play well in Miami shows how dialed he is with the irons this season.

In addition to the LIV finishes, Oosthuizen won back-to-back starts on the DP World Tour in December at the Alfred Dunhill Championship and the Mauritus Open. He also finished runner-up at the end of February in the International Series Oman. The 41-year-old has been one of the most consistent performers of 2024, regardless of tour.

For the season, Louis ranks 4th on LIV in birdies made, T9 in fairways hit and first in putting. He ranks 32nd in driving distance, but that won’t be an issue at this short course. Last season, he finished T11 at the event, but was in decent position going into the final round but fell back after shooting 70 while the rest of the field went low. This season, Oosthuizen comes into the event in peak form, and the course should be a perfect fit for his smooth swing and hot putter this week.

Opinion & Analysis

The Wedge Guy: What really makes a wedge work? Part 1

Published

on

Of all the clubs in our bags, wedges are almost always the simplest in construction and, therefore, the easiest to analyze what might make one work differently from another if you know what to look for.

Wedges are a lot less mysterious than drivers, of course, as the major brands are working with a lot of “pixie dust” inside these modern marvels. That’s carrying over more to irons now, with so many new models featuring internal multi-material technologies, and almost all of them having a “badge” or insert in the back to allow more complex graphics while hiding the actual distribution of mass.

But when it comes to wedges, most on the market today are still single pieces of molded steel, either cast or forged into that shape. So, if you look closely at where the mass is distributed, it’s pretty clear how that wedge is going to perform.

To start, because of their wider soles, the majority of the mass of almost any wedge is along the bottom third of the clubhead. So, the best wedge shots are always those hit between the 2nd and 5th grooves so that more mass is directly behind that impact. Elite tour professionals practice incessantly to learn to do that consistently, wearing out a spot about the size of a penny right there. If impact moves higher than that, the face is dramatically thinner, so smash factor is compromised significantly, which reduces the overall distance the ball will fly.

Every one of us, tour players included, knows that maddening shot that we feel a bit high on the face and it doesn’t go anywhere, it’s not your fault.

If your wedges show a wear pattern the size of a silver dollar, and centered above the 3rd or 4th groove, you are not getting anywhere near the same performance from shot to shot. Robot testing proves impact even two to three grooves higher in the face can cause distance loss of up to 35 to 55 feet with modern ‘tour design’ wedges.

In addition, as impact moves above the center of mass, the golf club principle of gear effect causes the ball to fly higher with less spin. Think of modern drivers for a minute. The “holy grail” of driving is high launch and low spin, and the driver engineers are pulling out all stops to get the mass as low in the clubhead as possible to optimize this combination.

Where is all the mass in your wedges? Low. So, disregarding the higher lofts, wedges “want” to launch the ball high with low spin – exactly the opposite of what good wedge play requires penetrating ball flight with high spin.

While almost all major brand wedges have begun putting a tiny bit more thickness in the top portion of the clubhead, conventional and modern ‘tour design’ wedges perform pretty much like they always have. Elite players learn to hit those crisp, spinny penetrating wedge shots by spending lots of practice time learning to consistently make contact low in the face.

So, what about grooves and face texture?

Grooves on any club can only do so much, and no one has any material advantage here. The USGA tightly defines what we manufacturers can do with grooves and face texture, and modern manufacturing techniques allow all of us to push those limits ever closer. And we all do. End of story.

Then there’s the topic of bounce and grinds, the most complex and confusing part of the wedge formula. Many top brands offer a complex array of sole configurations, all of them admittedly specialized to a particular kind of lie or turf conditions, and/or a particular divot pattern.

But if you don’t play the same turf all the time, and make the same size divot on every swing, how would you ever figure this out?

The only way is to take any wedge you are considering and play it a few rounds, hitting all the shots you face and observing the results. There’s simply no other way.

So, hopefully this will inspire a lively conversation in our comments section, and I’ll chime in to answer any questions you might have.

And next week, I’ll dive into the rest of the wedge formula. Yes, shafts, grips and specifications are essential, too.
