Rory McIlroy has claimed his second major title in four weeks and a third win in succession in a thrilling, weather-affected climax to the US PGA Championship.
McIlroy carded a closing 68 at Valhalla to finish 16 under par, one shot ahead of Phil Mickelson after a remarkable final day which finished in near-darkness, with the lights blazing from the clubhouse behind the 18th green.
Rickie Fowler and Henrik Stenson had been part of a three-way tie for the lead with Mickelson on the back nine but dropped shots on the closing stretch to finish two behind McIlroy on 14 under.
A torrential downpour which flooded the course and caused a delay of almost two hours meant it was a race against time to get play finished, so much so that Mickelson and Fowler stood aside on the 18th to allow the final group to tee off.
McIlroy’s drive finished dangerously close to the water to the right of the fairway, but a closing par was enough for the 25-year-old to become the first player since Padraig Harrington in 2008 to win back-to-back majors, his victories in the Open Championship and US PGA also sandwiched by a first World Golf Championship win in the Bridgestone Invitational last week.
Lifting the Wanamaker Trophy for the second time also makes the Northern Irishman the third youngest player after Tiger Woods and Jack Nicklaus to win four majors, just one less than the total won by the late Seve Ballesteros and two behind Nick Faldo.
