Rory McIlroy clashed with a fan on Sunday in the final round of the US PGA as chanting from the gallery once again drew his ire.

McIlroy was among the challengers on the final day but found heavy rough on the 16th as his bid for victory petered out. His next shot rebounded into a bunker, although he would go on to par the hole.
