By Mark Lamport-Stokes OAKMONT, Pennsylvania (Reuters) - Rory McIlroy left himself with plenty of work to do to make the cut at this week's U.S. Open after struggling to a seven-over-par 77 in the weather-delayed opening round on Friday. The Northern Irish world number three said he had not been in control of his golf swing while piling up eight bogeys and a lone birdie on the tough Oakmont Country Club layout and would need to shoot "something like 66" in the second round. "You see guys shooting in the red - there is a 66, a 67 – so there are scores out there to be had," four-times major winner McIlroy told reporters after finishing a distant 11 strokes off the early pace set by American rookie Andrew Landry.
