RORY MCILROY WON his second straight major championship and fourth of his young career, rallying on the back nine in the PGA Championship.

The tournament finished in near-darkness Sunday at Valhalla Golf Club, with the final two groups essentially morphing into a foursome as they raced to beat nightfall. A nearly two-hour rain delay set up the possibility of a Monday finish, especially if there had been a three-hole playoff.

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. Here’s the winning putt:

Rickie Fowler and Henrik Stenson tied for third, two shots behind.

Before McIlroy thanked Fowler and Mickelson for their sportsmanship on the last hole, the Holywood native managed to save the top of the Wanamaker.
