 Off and running in the final round, a hectic scoring day yesterday, Billy Horschel scrambled his way around the second nine on route to a 69 and a one-shot lead. He talked about his mental approach in majors. I'm a perfectionist at heart. I want everything to be perfect, and it's weird. At regular events, I know I don't have to be perfect to win, but at majors, I've always felt I had to be perfect.
