McIlroy still in contention despite double bogey finish

"There’s plenty of chances out there and if I can convert a few hopefully there is a low score in me.”

Japan’s Hiroshi Iwata equalled the lowest round in major championship history as Jordan Spieth took another step towards an even more impressive feat in the US PGA Championship.

Iwata fired an eagle, eight birdies and one bogey to card the 27th round of 63 in the majors, the 34-year-old covering the back nine at Whistling Straits in just 29 to improve on his opening 77 by 14 shots.
