GOLF.com: Brooks Koepka Cards Season-Best 63 at Byron Nelson After Intensive Putting Overhaul

Season-Best 63 at Byron Nelson: Ball-Striking Meets Putting at Last

Brooks Koepka fired an eight-under 63 in the opening round of the CJ Cup Byron Nelson at TPC Craig Ranch — his best score this PGA Tour season and his lowest Tour round since July 2020.

In his first full season back on the PGA Tour after four years with LIV Golf, Koepka's ball-striking has been consistently elite. He ranked 3rd in SG: Approach and 8th in SG: Tee to Green entering this week. The glaring weakness? Putting — ranked a painful 141st in SG: Putting through his prior starts.

The Warehouse Session and a Fourth Putter

To address the problem, Koepka spent a full practice day locked inside a putting studio he describes as "a little warehouse" at his Florida home. He worked on alignment, grip fundamentals, and tested multiple putters — emerging with a Scotty Cameron Fastback 1.5, his fourth putter of the season.

He cited the putter's increased toe hang as the key fit characteristic: "I've been fighting a toe release issue, and this putter seems to give me what I'm looking for with the CG up closer to the face."

The Results: SG: Putting Jumps to 10th

The adjustment translated immediately. Koepka drained a 17-footer for birdie, a 13-footer for eagle, a 10-footer for birdie, and a 14-footer for birdie — finishing the round ranked 10th in SG: Putting for the day.

Strokeslab Perspective

Koepka's SG profile this season has been a textbook case of elite approach play being neutralized by poor putting. A 3rd-place SG: Approach ranking producing underwhelming finishes is the clearest signal that the strokes gained on the way to the green were being surrendered on it. One round is a small sample, but the data-informed self-diagnosis — identifying a mechanical putting flaw and correcting it systematically — is exactly the process that separates elite players from the rest.
