GREENSBORO, N.C. — Si Woo Kim followed his tournament-record 10-under 60 with a third-round 64 Saturday to increase his lead to four strokes in the Wyndham Championship.
The 21-year-old South Korean had 18-under 192 total at Sedgefield, a stroke off the tournament 54-hole record set by Carl Pettersson in his 2008 victory.
Kim is in contention for his first PGA Tour victory for the second time in a month after losing a playoff to Aaron Baddeley in Alabama in the Barbasol Championship.
"I think (today) is much pressure, but I'm just trying to keep confidence. That's it," Kim said. "I feel very good now. My shots (are) much more consistent. … I'm experienced before like Alabama in Barbasol, that's good experience."
After making eagle and eight birdies Friday, Kim played the front nine in 3-under 35 Saturday with four birdies and bogey. He added birdies on the par-4 13th, par-5 15th and par-4 18th.
"I feel like really pressure because first time, first time I lead third round, but start very good, first hole and second hole start birdie," Kim said. "But after little pressure, I felt little better."
Rafa Cabrera Bello was second after 65 in the PGA Tour's regular-season finale.
"The greens are brilliant," Cabrera Bello said. "You play good and give yourself chances you will roll putts and that's what I'm going to try to do (today)."
Jim Furyk, Luke Donald and Kevin Na were at 13 under.
Furyk is playing his first event since shooting the first 58 in PGA Tour history Aug. 7 in the Travelers Championship. After playing a three-hole stretch in 4 under with a 60-footer for eagle on 15 and two birdies, he bogeyed the final two holes for 67.
"Had it rolling and then missed the fairway at 17 and I missed the fairway at 18 and the rough here doesn't allow you to hit a ball," he said. "It's hard to control."
