World number one Rory McIlroy faces missing the cut for a second week in succession after posting a nine-over-par 80 in the opening round at his home Irish Open on Thursday.

On a day of strong winds and intermittent showers, McIlroy hit nine bogeys and failed to record a single birdie in a nightmare round at the par 71 Royal County Down course.

The 26-year-old, who sits 150th in the 155-man field, trails leaders Padraig Harrington of Ireland and Germany's Maximilian Kieffer - who carded four-under-par 67s - by 13 strokes.

Northern Irishman McIlroy missed the cut at the last two Irish Opens and the BMW PGA Championship at Wentworth last week.

"Off the tee, I felt my game was ok and I put myself in good positions, but then as I got closer to the greens, the worse it got," said McIlroy.

"I didn't hit very many good iron shots and then from there my putting wasn't that good... I sort of just lost concentration on the greens.

"So, nothing went right and I was trying hard to birdie the last to try and break 80, but it just didn't quite happen."

"I've got to go out tomorrow and try my best and try to claw my way back inside the cut-off line and back into this tournament," he said.
