WHITE SULPHUR SPRINGS, W.Va. -- Jason Bohn's main goal after barely making the cut at The Greenbrier Classic was to get some extra rest before the final round.
Sweet dreams. And try not to think about being the co-leader heading into Sunday.
Bohn shot a 9-under 61 on Saturday and is at 11-under 199, tied with Sean O'Hair, Sung Joon Park and Bryce Molder on the Old White TPC course. O'Hair and Park both shot 66. Molder had a 67.
Bohn started strong with six birdies on the first 10 holes. After a bogey at No. 11, he regrouped with four more birdies over the final five holes, moving up 61 spots through the day.
It's setting up to be another close finish at the tournament, which debuted in 2010. Two were decided in playoffs, and the largest margin was two shots twice.
A crowded leaderboard has 27 players within four shots of the lead. Tiger Woods isn't among them. Woods struggled on the back nine, shot 71 and is seven strokes back.
Bohn's round was his best on the PGA Tour and included 14 one-putt greens. He shot 58 in a 2001 Canadian Tour event, the Bayer Championship. He missed the Old White TPC course record by two; Stuart Appleby shot a 59 there in 2010.
A two-time winner on the PGA Tour, Bohn has two runner-up finishes this season.
On Saturday, he was just hoping to play well enough to avoid an early tee time in the final round.
"I just wanted to sleep in, to be honest, so now I don't have to get up early in the morning," Bohn said.
Bohn birdied the final hole in the second round Friday to make the cut on the number at 2 under. He said he will need a similar round Sunday to have a chance at winning.
"You've just got to play very aggressive and play smart when you're out of position -- and aggressive when you're in position," Bohn said.
The last player to make the cut on the number and go on to win the event was Carl Pettersson at the 2010 RBC Canadian Open.
O'Hair lost to Jordan Spieth in a playoff at the Valspar Championship in March but had missed cuts in four of his last five events.
Seeking his fifth PGA Tour win and first since 2011, O'Hair had four back-nine birdies Saturday.
"I don't feel any pressure," O'Hair said. "I actually feel like a weight's been lifted off a little bit. I'm just happy to be in this situation again. This definitely beats struggling, I can promise you."
Molder reached 11 under with a birdie at No. 9 before stringing together nine straight pars.
"Somewhere midway through the back nine I just kind of lost rhythm," Molder said. "But my short game hung in there and kept me in it."
Molder's lone tour win came in a playoff at the 2011 Frys.com Open.
Park scattered four birdies in his bogey-free round. The South Korean has a runner-up finish at the Humana Challenge in his rookie season.
He doesn't expect to be nervous Sunday as he seeks his first tour victory.
"I've been in this situation before," Park said. "It's going to be the same -- another round for me."
Justin Thomas (66), David Hearn (68), Danny Lee (68) and Chad Collins (68) were at 10 under.
Third round co-leaders Jhonattan Vegas (76) and Scott Langley (74) both shot 2 over on the front nine and were far back in the field.
