The Northern Irishman made a confident start to his bid for a sixth major but came home in 41 to card a opening round of 74 and sit eight shots off the lead set by JJ Spaun at four-under par.
Brooks Koepka, a two-time winner of the US Open, has showed little in recent majors to suggest a third is on the cards but he was impressive on Thursday and is only two shots off Spaun’s lead.
Jon Rahm is a shot further back, as one of only ten players to finish the first round under par.
