What Rickie Fowler’s
Six Putters
Actually Tell Us
We started The Search with Rahm’s mid-tournament switch, moved through Morikawa’s inconclusive blade experiment, and watched Thomas win a Major the week he changed putters. Fowler’s data pulls all of it together — and adds a layer none of the others could.
Traditional stats like putts per round or greens in regulation tell you what happened. Strokes Gained tells you how much it mattered relative to the field.
The concept, developed by Columbia professor Mark Broadie, compares every shot against the statistical average outcome for all Tour players from that same position. Make a putt from 15 feet when the field averages 1.7 putts from there, and you’ve gained 0.7 strokes. Miss it and you’ve lost 0.3. Every shot on every hole, across every round, summed into a single number.
How many strokes per round a player gains or loses on the greens versus Tour average. The core metric throughout this series. Positive = better than field. Negative = worse.
Measures how much closer to the hole a player leaves their approach shots versus Tour average from the same distance and lie. The strongest single predictor of Tour earnings we’ve found.
Captures chipping, pitching, bunker play — any shot within 30 yards that isn’t a putt. Separates short-game skill from putting, which traditional stats bundle together.
The sum of all four SG categories: off the tee, approach, around the green, and putting. A positive total means the player performed better than the average Tour player across their whole game.
The short version: Strokes Gained is context-aware. Putts per round isn’t — it treats a 3-foot tap-in the same as a 40-foot lag putt. SG accounts for the difficulty of every shot, which is why it’s a far more honest measure of whether a putter change actually worked.
When a Tour player loses form, the data usually tells one of two stories. In the first, one category breaks while the others hold — a ball-striker who starts missing greens, or a putter who goes cold while still finding fairways. The problem is isolated.
In the second, everything moves at once. Approach play drops. Putting drops. Around-the-green numbers drop. Total SG collapses. This is a full-system failure — and it looks very different in the data from an isolated weakness.
One SG category moves while others stay stable. This is where a targeted fix — equipment change, technique tweak — has the best chance of making a genuine difference. You know what you’re solving.
All categories move in the same direction simultaneously. In Fowler’s 2022 data, approach fragmented before putting did — suggesting a root cause earlier in the system. A putter change can’t fix an approach problem.
The flip side: when Fowler’s game came back in 2023, every category improved at once. This tells you the recovery wasn’t purely the Jailbird — it was a player finding their whole game again, with the putter as one part of a bigger picture.
It changes what you’re looking at. If you only track putting when a player switches putters, you might see an improvement and credit the equipment. Tracking all categories simultaneously reveals whether that improvement is isolated or part of something bigger.
This is the most complete dataset in The Search. Eight years, more than 120 tournaments, six different putters. From top-10 in the world to 173rd, and back. DataGolf Strokes Gained numbers tracked across every category — putting, approach, around the green, off the tee, total.
That last part matters. The Rahm and Thomas pieces were putting stories — we tracked one category across one or two seasons. Fowler’s is a whole-game story, and it changes what The Search means.
The Scotty Newport Years
Filter the chart to the blue dots — the Scotty Cameron Newport era, 2017 to early 2020. Positive putting numbers most weeks. Wins at Phoenix and the Honda Classic. The data confirms what you’d remember from watching him play: he was a complete player in that period, and the putting wasn’t the weak link.

The Collapse Wasn’t Just the Putter
This is what surprised us most when we built this dataset. Filter to the 2021–22 era — the Cobra Vintage and Cobra Stingray periods. The putting numbers are poor. But look at the summary table below: the approach numbers were also poor. The around-the-green numbers. The total SG.
Compare this with Morikawa’s data. Morikawa’s ball-striking held firm while putting let him down — a genuinely isolated weakness where a putter change at least made conceptual sense. Fowler’s 2022 data shows something different: every category going in the wrong direction at once. And critically, the approach numbers fragmented first, before the putting followed.
The putter changes in that period look less like targeted fixes and more like a player trying anything. The Search, at its most desperate.
The Jailbird Numbers
Look at the summary table and compare the Jailbird era (2023) against the Cobra Stingray period. Putting improves: from −0.43 to +0.32. But approach also improves. Around the green improves. Total SG goes from negative to meaningfully positive. Every category moves in the same direction simultaneously.
That’s not what a putter change produces in the data. That’s what a player finding their whole game looks like. The Rocket Mortgage win in July 2023 wasn’t a surprise if you’d been watching the rolling average build through the spring.

The Search — Series Conclusion
Rahm: The Search can end — if you find the right one. Morikawa: Sometimes it just shows you a ceiling. Thomas: The timing can be everything. Fowler: The putter was part of a wider rebuild, not an isolated fix. Confidence in one club can unlock confidence across the whole bag — but the data suggests that only works when the rest of the game is ready to respond.
