World number one Rory McIlroy eagled the par-5 10th hole Friday at Valhalla to seize a two-stroke lead at the PGA Championship in his quest for consecutive major titles.
McIlroy, who captured the British Open last month at Royal Liverpool, put his approach just short of the green, 32 feet from the cup, then holed out from there to stand on eight-under for the championship.
The 25-year-old from Northern Ireland improved to three-under on the rain-hit second round, having answered a bogey at 12 with a 12-foot birdie putt at 13 and a 16-foot birdie putt at 15.
Sitting on six-under were Americans Steve Stricker and Ryan Palmer, both on their back nine for the day, and afternoon starters Lee Westwood and Kevin Chappell.
Sweden's fourth-ranked Henrik Stenson, Italy's Edoardo Molinari and American Jim Furyk were on five-under.
Tiger Woods, struggling to make the cut after opening on 74, was set for an afternoon start as well.
