Sebastian Munoz of Colombia continues to lead The Greenbrier Classic after a 2-under-par 68 on Saturday left him two shots ahead of Robert Streb in White Sulphur Springs, W.Va.
Munoz, who has led the PGA Tour event since firing an opening-round 61 on Thursday, posted a 54-hole score of 14-under 196. The PGA Tour rookie is bidding to become the first wire-to-wire winner in Greenbrier history.
Streb fired a 65 in the third round and moved to 12-under 198. He is one stroke ahead of PGA Tour rookie Xander Schauffele and Jamie Lovemark.
Schauffele and Lovemark both shot 66 to stand 11 under going into the final round on Sunday.
Still within striking distance is 53-year-old Davis Love III, whose 68 left him at 10 under along with Kelly Kraft (67) and Russell Henley (68).
Munoz opened the third round with a birdie at No. 1 but quickly followed with a bogey on the second hole. Another bogey and birdie on the front nine left him even for the round at the turn before he added two birdies on the back nine.
"I try to play boring golf. I try to hit the fairway and hit the greens," Munoz said. "Even though I try, I just seem to put myself into some trouble and then trying to make something happen and then kind of get on a good run, sometimes bad runs."
Munoz has a tournament-leading 19 birdies through three rounds, one more than Love.
"I think I had a good round today by the way I just hit the ball from the tee again," he said. "A lot of missed fairways in the first nine. Trying to get -- I think I was getting a little too quick, out of rhythm. And then we kind of managed to settle in with a couple clutch putts, save par, and good chips."
Streb, seeking his second career PGA Tour win, moved into position to challenge Munoz with a round that featured an eagle-3 on the par-5 No. 12 and also five birdies and two bogeys. He tied for second in the tournament two years ago.
Love III, at 53 years, two months and 26 days, could become the oldest winner on the PGA Tour in his 741st official event if he is able to come from behind in the final round. Sam Snead holds the record at 52 years, 10 months and eight days at the 1965 Wyndham Championship.
One of Love III's 21 career PGA Tour wins came two years ago at age 51 in the Wyndham Championship. His first tour victory came 30 years ago at the 1987 RBC Heritage -- and he would also set a record for longet span between first and last victories, which is held by Raymond Floyd (28 years, 11 months, 20 days) between 1963 and 1992.
"I've been hitting it pretty solid. If I can be patient with the putter and get some in, I can have a chance tomorrow," said Love III, who will serve as assistant captain for the U.S. Presidents Cup team later this year.
Defending champion Danny Lee is tied for eighth after a 70.
