Rory McIlroy made a glorious start to the 104th US PGA Championship as a five-under par opening round of 65 saw him claim the lead at Southern Hills Country Club in Oklahoma. The Northern Irishman – winner of the Wanamaker Trophy in 2012 and 2014 – enjoyed seven birdies and two bogeys with his putter as hot as the steamy Tulsa sunshine. Ad/> Starting out from the 10th tee alongside fellow major champions Tiger Woods (74) and Jordan Spieth (72) in the marquee group of Thursday morning, McIlroy chipped his ball stone dead for a birdie on the par-four 456-yard 12th hole before finding some vintage ball-striking and a clinical edge from short range.
