Koepka has been one of the best ballstrikers in golf since returning to the PGA Tour, ranking third in SG/apprach and eighth in tee-to-green. Unfortunately for the five-time major winner, the short game has not cooperated, ranking 141st in SG/putting. He changed out putters last week at the PGA Championship but the struggles were still there, which is why he's making another flatstick switch at this week's Byron Nelson to a Scotty Cameron Fastback 1.5. “Hopefully I can just kind of [get] some confidence with it and build some momentum off of it,” Koepka said earlier this week in Dallas. So far, it seems to be working, as Koepka is three under through three holes in the morning wave.
