When Aaron Rai walked off the 18th green at Aronimink on Sunday with the Wanamaker Trophy and a three-shot win in his pocket, one of the first analysts to put the result in context was former PGA Tour winner Johnson Wagner, on CBS's Scorecard Studios broadcast.
Wagner did not begin with the 109-year English drought or the 68-foot putt at the 17th. He began with the course.
"He's one of the hardest workers in professional golf," Wagner said of Rai. "He's won three times in Europe. Obviously, the Wyndham Championship on a Donald Ross venue at Sedgefield. And this golf course, when you look at Oak Hill specifically, it was built for a guy like Aaron Rai."
The reference to Oak Hill briefly conflated two championships; Aronimink, not Oak Hill, hosted this year's PGA Championship. But the Donald Ross pattern Wagner put on the table is the live observation, and it is the more interesting one.
Rai's first PGA Tour win came at the 2024 Wyndham Championship at Sedgefield Country Club in Greensboro, North Carolina. Sedgefield is one of the purest Donald Ross designs left on the PGA Tour rota: short by modern standards at 7,131 yards, with crowned greens, slope-defined approach shots and small landing areas off the tee that reward placement over power. Rai won there with one of the tour's most precise iron games of that season.
Aronimink, redesigned and restored repeatedly since Ross drew it in 1928 in Newtown Square, Pennsylvania, demands the same vocabulary at major-championship volume. CBS's coverage on Sunday repeatedly came back to the small landing areas, the elevated and firm greens, and what Wagner described as "the bunkers clustered specifically to create nightmare lies." Players spoke all week about feeling punished for the smallest loss of focus.
That setup is, by historical pattern, kryptonite for bombers and an open door for a player like Rai. The 31-year-old does not lead the PGA Tour in any single distance statistic. He drives the ball straight, controls trajectory and spin with his irons, and rarely takes himself out of a hole. Sedgefield rewarded the same skill set. So did Aronimink.
Rai's own description of his approach play on Sunday read like a Donald Ross instruction manual.
"The shots on 16 hit a great tee shot to hold the fairway there. That was a really hard fairway to hit," he said. "It was a great number for a five iron. The wind was off the left. The ball was slightly below, so it kind of just suited a shot that was falling off the wind."
There was no talk of trying to overpower the hole. The shot was matched to the wind, the slope and the ideal landing area. That has been the Rai signature for several years, but Donald Ross venues are where it has produced trophies.
The next time the pattern can be tested is itself a Donald Ross-adjacent question. Aaron Rai is now exempt for the foreseeable run of PGA Tour majors and signature events. His upcoming schedule includes the Memorial Tournament at Muirfield Village, the Travelers Championship at TPC River Highlands, and an Open Championship at Royal Portrush. None of those are Donald Ross designs.
For now, the data is small but pointed. Two Aaron Rai wins of consequence, two Donald Ross designs. A pattern Johnson Wagner saw quickly enough to lead with it before the Wanamaker had even cooled.
