David Frost bogeyed early, hit into the rough, the sand and missed short putts, but he still managed to emerge Saturday from a three-way tie to lead the Hardee's Classic at Coal Valley, Ill.
The defending champion shot a six-under-par 64 and was at 195, two strokes better than D.A. Weibring after 54 holes.
Frost and Weibring each stumbled with an early bogey before settling into a par-breaking rhythm across the soggy Oakwood Country Club course.
Weibring had an eagle and four birdies, but bogeyed 17 to finish with a 66.
"They are going to be hard to catch," said Kenny Perry, who had seven birdies in a 64 that put him third at 199.
"Frost is a great putter and a good front-runner. I don't expect him to fall," he said. "And D.A. is a veteran who knows how to win. He's not going to back down."
Frost and Weibring entered play tied for the lead with Dave Barr, who slipped to a 72 and was eight strokes back at 203.
Kenny Black had 65 and was fourth at 200. Ryder Cup team member Payne Stewart shot a 67 and was among four golfers at 201.
Gary Player shot a four-under-par 68 to share the second-round lead with Dale Douglass in the Senior Classic at Lexington, Ky.
Player and Douglass are tied at eight-under 136, one stroke better than Jim Albus, Dave Stockton, Bruce Crampton and J.C. Snead after two trips around the 6,798-yard Kearney Hill Links course.
Fred Couples, warming up for the Ryder Cup and going for his first European victory, shot a five-under-par 65 to take a one-stroke lead over David Feherty of Northern Ireland after the third round of the $847,000 Lancome Trophy at Saint-Nom-La-Breteche, France.
Couples has a three-day total of 10-under 200 on the 6,755-yard Saint-Nom course.
Second-round leader Mark James slipped to a share of seventh after a 72. Nick Faldo shot a 69 and is five strokes off the lead in ninth.
Jones, who has not won since the 1991 Rochester International, has a 54-hole total of 12-under 204.
Kris Monaghan (68) and U.S. Open winner Lauri Merten (70) are tied for second at 208.
Brandie Burton, a co-leader after the first round and the second-round leader by a shot, shot a 73 to drop into a tie at 209 with Tammie Green and Helen Alfredsson.
