Rory McIlroy is flexing his muscles coming down the stretch of the PGA Championship and now leads the rest of the field by six strokes. McIlroy is 4-under during his final round and 11-under for the tournament. He has four birdies and no bogeys during Sunday's final round.
Carl Pettersson and Ian Poulter are tied for second place at 5-under. Poulter looked like he was going to make a charge at McIlroy early but three straight bogeys on the back nine took him out of contention.
Defending champion Keegan Bradley is among three golfers who are tied for fourth at 4-under. Tiger Woods is a little further back at 3-under and tied for seventh place.
