World number one Rory McIlroy has won this year’s PGA Championship in near darkness at Valhalla Golf Club in Louisville, Kentucky.

Rory McIlroy has become the first UK player to win back-to-back majors.

Three players were still in contention at the final hole, with heavy rain having earlier led to a two-hour delay.

Rory McIlroy, 25, had earlier seen his overnight one-shot lead wiped out on the front nine and was three shots behind the leaders at one point before taking control after the turn.

A three-under 68 on the final day saw off Phil Mickelson, with Rickie Fowler and Henrik Stenson a shot further adrift.

Rory McIlroy later credited the “best golf of his life” with producing a summer beyond his “wildest dreams”.

His resurgence on the back nine capped an enthralling final day and saw him become the third youngest player of the modern era – after Tiger Woods and Jack Nicklaus – to win four of golf’s biggest prizes.

Rory McIlroy also becomes the first man to win back-to-back majors since Ireland’s Padraig Harrington in 2008.
