It may be too simplistic to table the US PGA Championship as a simple duel between the world No1 and world No2, but Scottie Scheffler and Rory McIlory have been a class apart from the rest of the field in recent weeks.
Scheffler has won four of his last five tournaments, including a second Masters, while McIlroy has been victorious in his last two tournaments, his most recent on Sunday involving a stunning late charge to come from behind and win by five shots.
