CORK, Ireland -- Mikko Ilonen opened up a two-stroke lead at the Irish Open at the end of the second round as Rory McIlroy failed to make the cut by one shot on Friday.
Ilonen added a 2-under 68 to his opening-round course-record of 64 to move to 10 under on the Fota Island Resort course.
The 34-year-old Finn birdied his opening hole but then stalled with eight straight pars ahead of an inward half that included four birdies.
"I wanted to at least get to 10 under par and I did that," Ilonen said. "It wasn't as easy today and I didn't hit the ball that well but I putted well and it was good enough."
Northern Ireland's Graeme McDowell (66), England's Robert Rock (66) and Frenchman Romain Wattel (65) share second place on 8 under while triple major winner Padraig Harrington (67) is tied for eighth on 6 under.
McDowell is looking to win the Irish Open for the first time and Rock has been runner-up twice before.
The loss of McIlroy over the final two rounds is a blow to event organizers. His second-round 69 was a mix of an eagle at the 10th, six birdies and a double bogey at No. 4 for an overall 1-over 143. It is the second year in succession McIlroy has missed the cut in his national open.
McIlroy's double bogey came after his tee shot clipped a tree and ricocheted out of bounds and over the fence into the adjoining Fota Island Wildlife Park.
"I'll be back next year and try and do better," McIlroy said.
