How Russell Henley Won the 2025 Arnold Palmer Invitational

The irons had an ordinary week at Bay Hill in March 2025, and Russell Henley won anyway. Half of his advantage over the field came from around the green.

Russell Henley won the Arnold Palmer Invitational at Bay Hill, 11 under par, by 1 stroke, after sitting 2nd and 1 back through 54 holes. That's the box score. The strokes-gained record, credit to Data Golf for the numbers underneath everything we do on Monday, tells a stranger story: 50 percent, exactly 50 percent, of Henley's advantage over the field came from around the green. Not the irons, not the putter, not the driver. The category that a typical 2025 winner to that point built about 12 percent of a win on, Henley built 50 percent of his on, 4 times the usual share.

Every one of his four measured categories finished positive that week, so nothing here is a lost category explained away. The categories that usually decide these things barely got out of the way, and the one that usually doesn't, took over.

How the win was built

Scoring conversion: 18 birdies or better, 9 bogeys against a field average of 11.6, 0 double bogeys or worse, over 72 holes. Final round 70, +1.4 strokes against the field that day. 2nd after 54 holes, 1 back.

*Average share across the 9 earlier 2025 winners with a strokes-gained record. Shares count only the categories where the winner beat the field, so a category where he lost strokes reads 0%, and rounding can leave the four shares a point short of or above 100. Strokes gained: Data Golf. The field is the 51 players who completed all four rounds.

Off the tee, Henley picked up 1.5 strokes, about a third of a stroke a round, 18th of 51. That's 12 percent of his advantage against a season-winner average of 16: a perfectly ordinary week with the driver.

Approach is the real surprise. Henley gained just 1.2 strokes with his irons, 22nd of 51, 10 percent of his advantage against a season-winner average of 38. Every one of the 9 winners before him this season had gotten at least 21% of the win from approach play. Henley is only the 2nd, after Rory McIlroy at Pebble Beach, to have his driving out-produce his irons, and McIlroy's driving that week carried 42 percent to approach's 25. His irons simply had a week off, in the category that most often wins these things.

Putting added 3.6 strokes, 10th of 51, about a stroke a round, 29 percent of the advantage against a season-winner average of 34. Comfortably good, a shade under what a typical winner draws from the flat stick, and by itself no explanation for the trophy.

And then around the green: 6.4 strokes, north of a stroke and a half a round, 1st of 51. 50 percent of his advantage, 4 times the season-winner average of 12, the largest around-the-green figure of any winner in the entire 2025 database. The next-largest share all year belongs to Hideki Matsuyama, 42 percent at the Hero, with Brian Campbell's 39 percent at the Mexico Open behind that. Among the 9 winners before Henley, nobody had cracked even 14 percent from this category. Full stop, the best short-game week any 2025 winner had posted.

The 5th category, scoring conversion, is where the tension shows. 18 birdies or better, 2nd-fewest of any winner so far this season (only Harris English's 15 is lower). 9 bogeys against a field average of 11.6, fewer than the field but nearly double the season-winner average of 5.2. 0 double bogeys or worse, matching the fewest of any 2025 winner. 11 under is the 2nd-closest-to-par winning score so far, behind only English's 8 under. Henley started Sunday 2nd, 1 back, and closed with a 70 that gained 1.4 strokes that day. Not a runaway. A hold.

The winning formula

Short-Game Survival, the 1st of the 2025 season. The rule: around the green plus putting supplied at least 55% of the advantage. This week: around the green plus putting carried 79% of the advantage.

Winning-formula ledger for 2025 through this event: Mistake-Free Win 4, Ball-Striking Blueprint 3, Driving Domination 1, Final-Round Takeover 1, Putting-Fueled Win 1, Short-Game Survival 1.

Short-Game Survival is a new label: the 1st time this season that around the green plus putting has supplied at least 55 percent of the win, and the combined 79 percent this week cleared that bar comfortably. Of the 9 winners before him, 3 had built their week on avoiding mistakes, 3 on tee-to-green ball-striking, 1 on the putter and 1 on the driver. Nobody had built one on the wedges and the flat stick together, so there's no earlier Short-Game Survival winner to measure this one against.

The closest comparison is Brian Campbell's around-the-green share of 39 percent at the Mexico Open, and even his approach share that week was still north of 40 percent. He had both the irons and the short game working. Henley had one of the two, and made it carry enough of the load to win anyway.

What this week added to the season

Across the 9 2025 winners before this one (9 with a strokes-gained record; the averages use those 9): average winning margin 2.0 strokes, average bogeys 5.2, average shares of advantage off the tee 16%, approach 38%, around the green 12%, putting 34%. This winner: margin 1, bogeys 9.

Across the 9 winners before him this season, the typical winning margin was 2.0 strokes and the typical bogey count 5.2. Henley won by 1 and made 9 bogeys, tighter than the field but looser than the year's typical winner, exactly the trade the short game covered for. To that point his 10 percent approach share was the lowest any winner had posted, and only 1 other 2025 winner ultimately finished with a lower share.

The database offers two more data points on Henley. At the 2026 Charles Schwab Challenge he won again, approach carrying 61 percent of a Final-Round Takeover, close to the opposite formula from Bay Hill. The following year's Arnold Palmer Invitational, same course, was won by Akshay Bhatia with a Putting-Fueled Win, putting supplying 58 percent. Two winners at Bay Hill, two formulas: two data points, not a verdict on what the course demands.

The Data Action angle

On the record, his irons and driver were ordinary all week, and the short game did the saving. What you might not have registered is how much of the tournament that scrambling carried: 50 percent. Not a complementary skill holding up a ball-striking week. The main event.

A par saved from well off the green doesn't look different on screen from a two-putt par, but in the strokes-gained record they are worlds apart, and Henley's week lived in that gap, over and over, for 72 holes.

With a margin of just 1 stroke, every category was decisive: subtract any one of the four, off the tee, approach, around the green or putting, and the record no longer says he wins. What the data can tell you is where the advantage came from: 50 percent around the green, 29 putting, 12 off the tee, 10 approach. What it cannot tell you is that the short game is why he won. It can only tell you where the edge sat.

The amateur translation

Strip it down to what he did. His approach play was middling, 22nd of the 51 players he beat, and instead of letting mid-green misses turn into bogeys, he turned most into pars, and the few that could have been doubles into single bogeys. That's the whole trick, repeated for 4 days.

The scoring principle underneath it: your score is decided far more by the quality of your next shot than your last one. A missed green isn't the mistake. A missed green followed by a chip that leaves you 8 feet is the mistake.

If you're a 5 handicap, you're probably scrambling well already, so hunt for the one hole a round where a chip runs past and the comeback putt misses. If you're a 15, getting up and down less often than you'd like isn't a flaw, it's the definition of a 15; your win is getting the first chip ON the green so the worst case is bogey. If you're a 25, take the putter from just off the green whenever the grass allows it, instead of the wedge.

The homework, one piece of it. The next three times you play, on every missed green, write down two things: did the chip or pitch end up on the green, and what did you score on the hole. Credit Fred Shoemaker for that idea: notice your own pattern before anyone tries to teach it to you, because feel misleads and the scorecard doesn't. Data Action Golf's Fatal Five audit tracks this exact category for your own game, three-putts, doubles, par-5 bogeys, short-range bogeys and blown easy saves, round by round.

Three findings

1. Around the green built the gap. Henley gained 6.4 strokes there, 1st of 51, producing 50 percent of his measured advantage, the largest around-the-green share of any winner in the 2025 database.
2. He was cleaner than the field and messier than a typical winner, in the same week. 9 bogeys beat the field's average of 11.6, but ran above the season-winner average of 5.2. The real mistake-avoidance story is the 0: no double bogeys or worse, matching the fewest of any 2025 winner.
3. The record says the week turned on Sunday, and stops there. Henley moved from 2nd, 1 back, to 1st, by 1, with a final round that gained 1.4 strokes. What the 54-hole leader did with that lead isn't in the data.

The week's lesson: the chip that finished on the green.

How to read these numbers

Strokes gained figures are Data Golf's, summed over the winner's four rounds and stated against the field's average for each round, so a positive number is strokes better than the field. Field ranks compare the 51 players who completed all four rounds. "Share of advantage" is the Data Action Golf reading: a category's strokes gained as a percentage of the winner's total across the categories where he beat the field. The 2025 winner average share is the mean of that figure across the season's earlier winners with a strokes-gained record, so it moves as the season goes on. The winning-formula label is assigned by fixed rules checked in a set order; the first rule that fits wins, and the labels describe how one week's advantage was distributed, nothing more. These numbers describe this tournament. They do not predict the next one. Full method: how Data Action Golf reads a winner and what strokes gained measures.
