Brooks Koepka shot a course-record 63 on Thursday, and becuase he’s not one to put up high numbers, oddsmakers have adjusted the PGA Championship’s (live) odds and made Koepka a heavy favorite heading into Friday’s second round.

The defending champion, and three-time major winner, is now listed at nearly even money (+150), less than 2-1, to take home a second Wanamaker Trophy.

Koepka started out as one of the top-5 favorites alongside Tiger Woods, Dustin Johnson, and Rory McIlroy, but after Thursday’s sizzling performance, the bookmakers aren’t taking any chances.
