Brooks Koepka became the first player in over 20 years to win back-to-back PGA Championship titles, becoming a four-time major winner in the process, but could the American give himself the perfect late birthday present by becoming the first man in the Open Era to win three consecutive titles?
Given that Koepka has dominated this tournament in recent years and has been a regular major winner over the past couple of season it is no shock to see him heading up the outright betting for the 2020 PGA Championship, but the bookies believe there are some serious threats to his quest in the form of Rory McIlroy, Dustin Johnson, Tiger Woods, Justin Thomas, Justin Rose, Jon Rahm and Jordan Spieth.
