The five-time major champ's final tune-up for the year's first major didn't go as planned. With rounds of 75 and 69 at the Texas Children's Houston Open, Koepka missed the cut at Memorial Park Golf Course. Even more troubling? He struggled with the one part of his game that has been sharp since returning to the PGA Tour this year.
