Rory McIlroy won his second straight major championship and fourth of his young career, rallying on the back nine in the PGA Championship.

McIlroy took care of that by shooting 3-under 68, beating Phil Mickelson by one stroke. McIlroy rallied from a three-shot deficit at the turn, setting up an eagle at the 10th with a brilliant second shot. He built a two-stroke lead with a 10-foot birdie putt at the 17th.

McIlroy finished at 16-under 268.
