Research and Key Stat Model: US Open at LACC

My approach to golf betting and daily fantasy is deeply rooted in statistical modeling. It’s not the only way to go about handicapping a golf tournament, but I think it’s the best way. It helps me eliminate biases and identify golfers purely based on whether they are in good form and if their game syncs up with the course they are about to play.

In this article, I will put together a weighted statistical model specific to the course and tournament. The statistics are chosen and weighted based on historical data from previous tournaments. In addition to course specific data, I will also look at recent form and any other potential relevant angle. The model accounts for the last 50 measured rounds, with the more recent rounds receiving increasingly more weight.

This Week’s Stats

SG: Approach — Approach shots are the bread and butter of every statistical model. No one is going to survive a US Open if they aren’t at the very least above average in their approach play.

Scottie Scheffler
Jon Rahm
Wyndham Clark
Collin Morikawa
Justin Rose
Emiliano Grillo
Viktor Hovland
Hideki Matsuyama
Sepp Straka
Tony Finau

Opportunities Gained — This stat measures birdie opportunities within 15 feet from the hole plus any greens hit in under regulation (on the green with an eagle putt or better). It’s a bit more accurate than a green in regulation stat because not all greens in regulation are the same considering a 50-foot birdie putt and 4-foot birdie putt are scored the same. I think this will be super important this week as if you aren’t super accurate, you’re probably not holding the green.

Wyndham Clark
Sungjae Im
Nick Taylor
Hideki Matsuyama
Tyrrell Hatton
Xander Schauffele
Patrick Cantlay
Adam Hadwin
Jordan Spieth
Jason Day

SG: Off-the-Tee (with added emphasis on distance)— Off-the-tee always pops in US Open look backs. I did boost distance a tad by adding it into column so that it double counts length just a tiny bit.

Scottie Scheffler
Patrick Cantlay
Shane Lowry
Michael Kim
Xander Schauffele
Tyrrell Hatton
Viktor Hovland
Jon Rahm
Jordan Spieth
Tommy Fleetwood

Par 3 Scoring (225+)— There are some Par 3s on this course that most amateurs couldn’t reach with their driver. Heck, I’m not sure Zach Johnson will be able to reach the two 280+ holes. Either way, having the ability to score or at least tread water on these holes will be crucial.

Jon Rahm
Shane Lowry
KH Lee
Joel Dahmen
Adam Handwin
Alex Noren
Cam Young
Sergio Garcia
Keegan Bradley
Scottie Scheffler

Proximity: 200+ — The LA Country Club has long holes and also some angles that make holes longer than they seem. It’s going to be important to have the long irons running pure to contend for the year’s third major.

Jon Rahm
Joaquin Niemann
Tom Hoge
Tony Finau
Scottie Scheffler
Justin Rose
Rory McIlroy
Dustin Johnson
Charley Hoffman
Hideki Matsuyama

Recent Form — Professional golfers can play well at any given tournament, however when it’s always important to give an added boost to guys who are in a groove with their swing and have been playing well leading up to a tournament.

Difficult Course Form – The players that have gained the most strokes, on average, at courses rated difficult to par.

Scottie Scheffler
Viktor Hovland
Rory McIlroy
Xander Schauffele
Patrick Cantlay
Jordan Spieth
Justin Rose
Tommy Fleetwood
Wyndham Clark
Tyrrell Hatton

Putting from 5-10 Feet (Lightning/Fast) – There are going to be a ton of slippery par saves from around 7-8 feet that could be the deciding factor when it’s all said and done. The best players at rolling in shorter putts on lightning fast greens will have a big advantage

Tommy Fleetwood
Taylor Moore
Matt Kuchar
Harris English
Ryan Fox
Taylor Montgomery
Justin Rose
Brooks Koepka
Cam Smith
Brian Harman

Bogey Avoidance – The tough test the US Open sets forth requires players to avoid making big numbers. Picking your spots for birdie chances and doing your best to par your way through the course should be the focus of most this week. Below are the top guys at avoiding boxes on the scorecard

Jason Day
Wyndham Clark
Tommy Fleetwood
Scottie Scheffler
Hideki Matsuyama
Tyrrell Hatton
Xander Schauffele
Patrick Cantlay
Adam Hadwin
Jordan Spieth

Peaking and Fading – One of the flaws that I often come across in modeling is focusing on a fixed range of time or rounds and taking a wider view to determining if a player is peaking or fading leading up to an event. For instance, a player’s high rating in a model that only focuses on the last 50 rounds could be a result of playing well four months ago. In this section, I will lay out the players who have improved or faded statistically over the course of their last 50 rounds.

Peaking

Hideki Matsuyama
Rickie Fowler
Jordan Spieth
Corey Conners
Michael Kim

Fading

Tom Hoge
Max Homa
Cam Young
Justin Suh
Si Woo Kim

Stat Model Top 50 Rankings

1. Scottie SchefflerScheffler has been lacking with the putter but rates out top seven in approach, long par 3s, 200+ proximity, and opportunities gained. He’s also tops in difficult courses and recent form.
2. Xander SchauffeleXander rates out seventh in recent course fit and fourth in long term course fit. He rates out fourth in difficult to par courses and sixth in recent form.
3. Patrick CantlayCantlay rates out top ten in bogey avoidance opportunities gained, and 8th in the off the tee metric. I will say he hasn’t made much noise in majors in his career despite rating well in key stats.
4. Wyndham ClarkWyndham Clark is the first surprise on the list. He’s played well this season and rates out well thanks to top three ratings in bogey avoidance, opportunities gained, and approach.
5. Brooks KoepkaKoepka is placed here by me manually because he doesn’t have the requisite rounds to land in the model, but he fits the bill with his length off the tee and his ability to contend on difficult courses in difficult fields.
6. Viktor HovlandHovland rates out top 12 in approach, 200+ approximately, and bogey avoidance. He rates out second in form and difficult courses as well.
7. Tyrrell HattonHatton lands in the top 15 in off the tee, long par 3s, 5-10 foot putts, and bogey avoidance. Hatton is also in the top ten for difficult courses and recent form.
8. Jon RahmThis is probably the lowest Rahm has been and it’s a result of his scoring on difficult courses. Although he just won the Masters, he hasn’t been lights out when the scoring is relatively low. That said, he’s still eighth and a great bet to contend this week.
9. Rory McIlroyRory is fading a tad as he rates out 16th in recent course fit but 10th long term. He’s third in both form and strokes gained on difficult courses
10. Rickie FowlerFowler is really playing well. Though I don’t think he can win this event, he is a solid putter, has been great in avoiding bogeys and approach.
