Rory McIlroy’s final round at the PGA Championship unraveled at Aronimink Golf Club when a spectator’s shouted “U‑S‑A!” provoked a terse exchange. After a tee shot landed in thick rough on the 16th, the Masters champion muttered an expletive and told the fan to “shut up,” drawing security’s attention. McIlroy, a 2025 Ryder Cup runner‑up, said the chant felt out of place on the event stage.

McIlroy entered Sunday three strokes behind the leaders, hoping to surge past Aaron Rai. A mis‑hit from 37 yards of rough on the par‑5 16th bounced into a bunker, leaving him three shots off the lead. He finished with a 69, tied for seventh at four under, posting only one birdie on the front nine and missing a short birdie putt on the 12th.

Earlier this week he warned that hostile crowds surface mainly during Ryder Cup years, recalling a tougher episode at Bethpage in 2025. Sunday's incident, while less severe, highlighted the pressure elite players face on demanding Donald Ross layouts. Missed birdies on the two par‑5s and a bogey on the 13th kept him off the podium.
