When practicing for Thursday’s opening round of The Players Championship, a college golfer heckled the four-time major winner from behind the 18th tee box at the Ponte Vedra Beach, Fla., course, with McIlroy later taking matters into his own hands — literally.

Rory McIlroy has refused to comment on being heckled by a top US college golfer during a practice round at the Players Championship. The world number two declined to discuss the matter with reporters after his opening round.
