Out of sorts Rory McIlroy in race against time after opening 77

Forget about the 34 putts that the world No 3 had in the joint worst round of his US Open career, matching his opening 77 at Olympic Club in 2012, where he missed the cut.
The problem is not desire but time, and while he planned to return to the range yesterday evening to try and correct his swing before wrestling the gorilla of Oakmont for the second time today, he may already have done too much damage with his seven over par opening round.
