After entering the week as one of the three co-favorites to win this week's PGA Championship, Brooks Koepka on Thursday staked himself to the Day 1 lead at Bethpage Black and took over as the new solo favorite for sports bettors.
Koepka at 7 under is now 5/4 at the Westgate Las Vegas Superbook, followed by Dustin Johnson, 1 under, at 10/1 and Tommy Fleetwood, 3 under, at 12/1.
Koepka, Johnson and Tiger Woods entered the week at 10/1.
Woods, who finished runner-up to Koepka at last year's PGA and is coming off his 15th major victory, has dropped to 30/1 after a first-round 72 left him nine off the pace.
The Westgate's odds down to 60/1 are listed in the tweet below.
