Fresh off his runner-up finish at the U.S. Open, Brooks Koepka is the favorite to win the Open Championship next month at Royal Portrush.

Koepka was listed as a 6/1 favorite to hoist the claret jug, according to the Westgate Las Vegas SuperBook. The 29-year-old Koepka has won four of his past nine majors and finished runner-up in two more during that span. He has two top-10s in five career starts at The Open, with his best finish of T-6 coming at Royal Birkdale in 2017.

Rory McIlroy followed at 10/1 while Tiger Woods and Dustin Johnson are each 12/1. Reigning Champion Golfer of the year, Francesco Molinari, is 20/1. Gary Woodland, who won his first major title Sunday at Pebble Beach, is 50/1.
