Matthew Wolff takes a two-shot lead into the final round at Winged Foot as he looks to become the first debutant in 107 years to win the US Open.
The American, 21, had six birdies in a scintillating five-under 65 to improve to five under par overall in New York.
Bryson DeChambeau is three under, with Louis Oosthuizen at one under par.
Northern Ireland’s Rory McIlroy is in contention at one over par after “a good round” of 68 – one of only seven players to shoot under par on Saturday.
The world number four, who finished a couple of hours before Wolff, said he felt he would have a chance on the final day if he could stay within six of the lead.
“The key for me was just to play the first five holes well. I saw from a few of the guys early on those holes were playing really tough,” said McIlroy, after a round containing three birdies and one bogey. (BBC)
