Current odds: 10/1
World ranking: No. 3
Best PGA Championship finish: Won — 2018
One thing to know: Few players have been as dominant at majors over the past four years as Brooks Koepka, with three wins, and five more top-10 finishes since 2015. As the reigning PGA Champion, and coming off a second place at the 2019 Masters, Koepka will be one of the most popular bets in the field.
