Brooks Koepka's putting prowess at the RBC Canadian Open is a testament to his resilience and a potential harbinger of success at the US Open. Despite a disappointing Saturday round, Koepka's performance on the greens has been nothing short of remarkable, especially considering his struggles with putting this year. With a strokes gained putting rating of 2.47 per round, Koepka is on track to challenge his personal best, which was achieved at the Honda Classic in 2015. This improvement is all the more impressive given the absence of data from LIV Golf's early years. Koepka's performance at TPC Toronto is a clear signal to his rivals that he is a force to be reckoned with at the US Open, where he has already tasted success twice. The question remains: can Koepka maintain this form and challenge for another major title? Only time will tell, but one thing is certain: Koepka's putting has become a reliable weapon in his arsenal, and his ability to adapt and improve is a hallmark of a true champion.
