Brooks Koepka and Rickie Fowler are listed as the new betting favorites to win the PGA Championship after the opening round Thursday.
Koepka fired a 3-under 68 in the morning to sit one shot off the lead held by Kevin Kisner and Thorbjorn Olesen, while Fowler rebounded from a triple-bogey on his front nine to post a 2-under 69 in the afternoon rounds. Both players are listed at 6-1 to win the tournament in Bodog's updated odds.
Pre-tournament favorite Rory McIlroy struggled on the backside of his 18 holes on Friday, finishing at 1-over par, five shots off the lead. Despite that deficit, the 28-year-old is still listed third at 9-1 to win the event. Hideki Matsuyama built off last week's win at the WGC-Bridgestone with a 1-under 71 and is also 9-1 to win the tournament.
Dustin Johnson and Jordan Spieth are next on the betting board at 10-1 and 14-1 respectively, while co-leader Kisner is 16-1 to hold the lead through Sunday's conclusion.
