James Hahn blamed an unruly fan for contributing to his 3&2 loss to Jason Dufner in the first round of the WGC Match Play Championship last Friday - marking yet another week on the PGA Tour where fan behaviour has become an issue.
Hahn took to Twitter to claim that on the penultimate hole of his match against Dufner, a "guy yell[ed] purposely on my back swing."
The tweet was later deleted, but the full text read: "Fought hard today after a bad start. 2 down, 4 to go, guy yells purposely on my back swing. Whether we like it or not, this is where the game is going. My fault for not expecting the worst from fans. Just sucks to lose a match that way."
It remains unclear which shot Hahn is referring to, but he did make a bogey five on the par-4 15th while Dufner made par to move to 3 up in the match.
He followed the first tweet with a correction that read: "I respect and love all golf fans but I can expect bad behavior from them. And I'm not blaming the fan for losing the match. Just disappointed I lost the deciding hole in that fashion."
Hahn then got into a heated Twitter exchange with several users.
The controversial moment marks a string of recent player-fan related issues with Tiger Woods being put off a putt at the Genesis Open, Justin Thomas ejecting a fan from the Honda Classic and Rory McIlroy being irate at a fan calling out his wife.
