PGA Championship history: T-4 in 2016 (and T-5 in 2015).
Current Vegas odds: 25/1
Reason to pick: After capturing his first major championship at the U.S. Open, Koepka returned to action following a month of barely touching his clubs and finished T-6 at the British Open. Yeah, he's that good. And he's even better in the game's biggest four events,
coming in fifth in our recent ranking of current players in major championships.
Cause for concern: Koepka has never teed it up in competition at Quail Hollow, a course most of his peers are very familiar with. But as he showed at Erin Hills and Royal Birkdale, he doesn't need much time to adjust to new surroundings.
