Jackson Suber: Brooks Koepka shot a 6-under 64 on Thursday to share the first-round lead at the RBC Canadian Open with Sahith Theegala, Emiliano Grillo, Eric Cole, Matthew Anderson and Sam Burns.
The round was defined by an unusually red-hot day on the greens. Koepka made nearly 108 feet of putts, finished fifth in Strokes Gained: Putting for the round and gained 3.491 strokes on the field with his putting — figures that flipped a season-long weakness into Thursday’s biggest strength.
Koepka’s scoring surge was sudden and severe. He was even par after eight holes with one birdie and one bogey, then ran off seven birdies in his last 10 holes, carding a 5-under 30 on the back nine and closing with birdies on the final two holes. His 141-yard wedge on the par-3 14th checked up 19 feet, 3 inches short before he made the putt that helped ignite the run.
He described the turnaround as a mental and mechanical reset. "It was just a culmination of kind of freeing the mind," Koepka said, and added that a small technical tweak helped: "If you just change one thing, move the ball position back a little bit with the putter and kind of help me free up the mechanical side of it and not really think of anything other than just have it slightly a bit back of where it's been." He also noted, "Ball striking has been good all year," and that the round felt "Better than OK, it was solid, but nothing spectacular. I just need that putter to heat up.... Hopefully three more days of this."
The context makes Thursday’s numbers sharper. Koepka entered the week ranked 136th in Strokes Gained: Putting and had gained strokes on the greens in only two of his last six starts. This is his 12th event back on the PGA TOUR since accepting the terms of the Returning Member Program; he has missed three cuts since returning and his only top-10 was a tie for ninth at the Cognizant Classic in The Palm Beaches. He has shown flashes elsewhere this season, with a tie for 12th at the Masters and a tie for 14th in his most recent start at THE CJ CUP Byron Nelson, an event won the previous week when Wyndham Clark shot 60 on Sunday.
The friction is obvious: Koepka sits atop the leaderboard after an exceptional day with the putter, yet the season-long data painted a different picture. Converting a poor season mark — 136th in Strokes Gained: Putting — into a top-five round in the metric is a significant swing, but it rests on a single session of hot holing and a modest setup change. That jump raises the hard question for the following days: was Thursday a reset or an outlier?
What matters next is straightforward and immediate. Koepka has three more rounds to prove the putter remains a driver of his score, not a one-day fluke. He acknowledged that need plainly: "I’ve been knocking on the door playing good enough to win... it’s just been the putter that’s holding me back. Hopefully three more days of this." If the numbers — nearly 108 feet of made putts and +3.491 strokes gained on the greens — repeat, Koepka will be a legitimate contender; if they don’t, Thursday will stand as a single bright headline in a season of uneven returns.
