US Open 2014: McIlroy 'fairly content' with opening 71
Rory McIlroy says he was happy with his ball striking in Thursday's opening 71 at the US Open but struggled with the pace of the greens.
"I played well. I hit 14 greens and missed only one fairway I think but I didn't have the pace of the greens quite right," said McIlroy, who is six behind leader Martin Kaymer after day one.
"It was a grind out there today but I am fairly happy after that."
