Rory McIlroy: Masters champion swears at heckler at US PGA Championship

Rory McIlroy, the reigning Masters champion and world number two, shouted an expletive at a heckler who distracted him at a critical moment during the final round of the US PGA Championship at Aronimink. McIlroy told the fan to 'shut up' and appeared to urge security to remove the spectator from the course. The incident drew comparisons to McIlroy's heated Ryder Cup campaign the previous year, when he faced frequent abuse from US supporters during Europe's victory at Bethpage.
