Englishman David Howell has hit a round of 64 to lead the Irish Open going into the final day's play at Killarney.
The two-time Ryder Cup winner had begun the day on four-under but some excellent putting helped him finish the session on 11-under, sharing the top of the leaderboard with Australian Richard Green and fellow Englishman Simon Dyson.
The 36-year-old's playing partner, Rory McIlroy, fared less well, posting a round of 72 to put him eight shots behind the lead.
"I'm flying now - I must be one of the hottest players in the world," joked Howell.
"I've not been in the best of form, so I was intrigued how I was going to be playing with Rory. He's the star of world golf.
"But there were no nerves and I think I was inspired by the atmosphere. The crowds were amazing," he added.
Despite the eight-shot deficit, US Open winner McIlroy was positive about his performance.
"It was not a great start, but I got it together at the end and one over is not too bad considering how I played at the start," the 22-year-old said.
"At this tournament you're trying so hard to play well for not just yourself, but for everyone else. Sometimes you can just find yourself trying a little too hard and pushing a bit too much."
Fellow Irishman Graeme McDowell joined McIlroy on three-under.
