Spencer Levin shot a three-under-par 69 to lead by one at the end of the third round of the Memorial Tournament as Tiger Woods battled to stay in contention.
On a day when low scores were few and far between at Muirfield Village, with only 14 of the 71 remaining players going under par, Levin carded four birdies and an eagle against three bogeys to sit eight under overall, one stroke ahead of overnight leader Rory Sabbatini.
But it could have been even better for Levin, who turned in 32 and was five under for his round after 10, before bogeying the 12th and 16th.
"I had some really good breaks, so I'll take it," Levin told www.pgatour.com. "I played pretty solid, but it's nice to have a couple good breaks.
"But if you're going to shoot the low round of the day out here on the Tour, or any day, you're going to have a couple good breaks or make long putts or chip in generally."
Sabbatini was one under today to lie seven under overall, two strokes ahead of Rickie Fowler and three ahead of Woods.
While Fowler equalled Levin's best-of-the-day 69 with four birdies and a bogey, Woods carded four bogeys on the back nine to more than cancel out his three birdies in a one-over 73.
"I certainly probably shot the highest score I could have shot today considering the way I hit it," Woods said.
"But I'm only four back, and out here with the conditions, supposed to be like this tomorrow again, anything can happen."
Sweden's Henrik Stenson was leading the European challenge as a 71 left him three under, alongside Japan's Ryo Ishikawa and American Jonathan Byrd.
First-round leader Scott Stallings was in a group seven on two under after a 75, while England's Justin Rose was level par and a trio of his compatriots - Brian Davis, Greg Owen and world number one Luke Donald - were three-over.
