NEWTOWN SQUARE, Pa. (AP) — Rory McIlroy’s frustrating final round at the PGA Championship on Sunday boiled over with an angry exchange with a fan after a “U-S-A!” shout from the gallery at Aronimink Golf Club.An errant shot out of heavy rough at the scoreable 16th hole derailed McIlroy’s come-from-behind bid, and he appeared to respond to the shout by using an expletive while telling the fan to “shut up.” The exchange summarized the two-time Masters champion’s confounding final round. He was not alone, as Jon Rahm, Cam Smith and Xander Schauffele had their chances and failed to catch Aaron Rai.McIlroy said earlier in the week that the outlandish and abusive fan behavior he endures — like at the Ryder Cup last year — is usually limited to one week every four years, when the matches are contested in the U.S.Sunday’s interaction, far less severe than what he heard at Bethpage in New York, seemingly just came at a bad time.
McIlroy was three strokes behind Rai on the par-5 16th hole when his second shot out of rough from 37 yard was short and bounded into a bunker. The two-time Masters champion spun, glared at the spectator, grumbled under his breath and seemed to point out the person to security.
