For a while now, I’ve been intrigued with the Stack and Tilt golf swing. I read about it in 2007 in the first Golf Digest article. I briefly tried it for myself. I wrote about it a number of times. I watched the instructional DVDs. Since all that happened, I have read tons of comments from readers about their success with the swing. I have received literally hundreds of comments and I think all but one were positive.
What I want to know is, how effective is the swing? Is it really better than a conventional swing or some of the other variations out there?
From all that I’ve read about the swing, I know of a handful of tour pros that use the Stack and Tilt swing. Some are featured in the ads for the DVDs. Aaron Baddeley was featured in the Golf Digest article. I read about Mike Weir adopting the swing.
I decided that I would set out to do an analysis of statistics for that handful of pros to see if I could find any evidence that the Stack and Tilt swing has transformed their games for the better. I went back as far as 2000 (or as far as I could) and looked for trends in several statistical categories for Aaron Baddeley, Will MacKenzie, Dean Wilson, Charlie Wi, Mike Weir, and Tommy Armour III.
Methodology
For each pro, I considered greens in regulation, driving accuracy, driving distance, scoring average, and money earned for a period from 2000 through 2008. I thought these things would be good indicators of whether a player’s swing was improved over that period.
For each player, I gathered stats as far back as I could for any year where that player played at least 20 competitive rounds. In a year where a player split time between more than one tour, I took stats from whichever tour a player spent the most time on. Overall, I preferred PGA Tour stats and PGA European Tour stats, over Nationwide Tour stats wherever possible.
Possible Problems
If you were under the impression that this was a formal scientific study, I hate to disappoint, but there are simply too many variables to make a definitive determination. I’m looking for trends that could point to player improvement attributable to the Stack and Tilt. At the same time, it’s not always possible to correlate improvement with the Stack and Tilt, because the player could have been putting in a lot of short game or putting work in the case of noticeable improvement, or could have been injured or mentally distracted in the case of a decline.
It’s also not possible for me to know exactly when each player began adopting the Stack and Tilt swing. However, I do have some references to go on. In The Scorecard Always Lies, by Chris Lewis, there is mention of Andy Plummer and Mike Bennett (architects of the Stack and Tilt) as well as when certain players began working with the two.
Here is what I can glean from Lewis’ inside information:
- Plummer and Bennett started working on Tour in 2004 and had their first success with Steve Elkington late in 2005
- They got their first victory with Aaron Baddeley in 2006. I’m presuming they began working with him in the 2005 off-season, but that’s a guess.
- They began working with Tommy Armour III, Dean Wilson, and Grant Waite by the end of 2005.
- By 2006, their appointment books were swelling.
In addition, according to a Golf Digest article, Mike Weir had adopted the swing by 2007.
The Data
All the stats were gathered from the PGA Tour and PGA European Tour homepages. If you’d like to look at the raw data I collected, you may view the spreadsheet here. The charts below were constructed directly from that data, using Microsoft Excel.
Without further ado, here are the findings for each player in the categories greens in regulation, driving accuracy, driving distance, scoring average, and money earned for a period from 2000 through 2008.





Analysis
I’m seeing some very interesting things in there. Let’s have a look at each category.
- Greens in Regulation – Clearly Aaron Baddeley has been trending upward since beginning work with Plummer and Bennett. After some solid years earlier, Mike Weir has regained some of this ground in the GIR category, but not nearly to the point where he was at the beginning of the decade. If you smooth the ups and downs, all the players except for Will MacKenzie have been trending mostly upward for the last few years.
- Driving Distance – This is probably the least meaningful of the stats I chose for this exercise, as driving distance is not generally an indicator of success without strength in the driving accuracy category. The results were mixed, with Baddeley, Armour III, and Weir trending upward the last few years (after drastic declines in the previous few years, I might add), while the rest were generally moving downward. It should be noted that Tommy Armour III turns 50 this year, which might explain the loss in distance from 2003-2006, but doesn’t explain why he added almost ten yards between 2006 and 2008.
- Driving Accuracy – I’m surprised that these results are so mixed, since consistency is supposed to be the bread and butter of the Stack and Tilt. Weir and MacKenzie have been pretty much on a plateau for quite a while. Baddeley looks like he made a huge improvement right around the time be began adopting the Stack and Tilt. Tommy Armour III had a nice upward movement since 2004 with the exception of 2008. Overall, with the exception of Weir and MacKenzie, the other guys were showing improvement, but Armour III and Wi had what might be considered one unusually good and one unusually bad year since 2004.
- Scoring Average – To me, this is the most telling of the stats. Every single one of the players has been trending downward since 2005, with the lone exception of MacKenzie in 2008. That can probably be chalked up to a bad year given that he saw drops in just about all the categories in 2008. Without a doubt, though, scores have been dropping steadily in the last few years.
- Earnings – Again, another telling stat. All of the players saw generally increased earnings between 2005 and 2008.
Conclusions
As I said at the top, this study is fairly unscientific and, in fairness, I don’t know that I can make any absolutely definitive conclusions. However, with these five players, it seems clear to me that each has decreased his average score and increased his earnings since Andy Plummer and Mike Bennett hung out their shingle on Tour and started working with these guys.
There could be other factors involved. For instance, there could have been new or renewed efforts to work on the short game, putting, fitness, or the mental game. There could have been improvements in equipment. There are many possible explanations.
In some cases, like with Mike Weir, there were big drops in performance from earlier successes. In his case, he had a big year in 2003 which included a Masters win. His rebound from his subsequent slump could have been a natural one. Also interesting is that he still hasn’t regained his pre-2003 strength in any of the categories.
At the same time, I think there is too much correlation to say that the Stack and Tilt isn’t at least partly responsible for increased success for these five players. The fact that all five showed a generally upward trend in both scoring and earnings tells me that they all started doing something that worked for them and the one thing that I know they have in common is adoption of the Stack and Tilt golf swing.
I think that speaks volumes to those of you out there who have been working on switching to the Stack and Tilt. If the swing can show this kind of improvement at players at that level, then it stands to reason that average players will benefit from its simplicity and consistency. From the massively positive reaction I’ve heard from players around the world, I’d say that hypothesis has already been proven.
For those of you who haven’t given it a shot, you might want to consider it. At worst, you won’t improve and can go back to whatever you’re doing now. At best, you might start shaving strokes like we’ve seen from the PGA Tour all the way down to the weekend hacker.
