Si Woo Kim shot a tournament-record 10-under 60 on Friday at Sedgefield to take the second-round lead in the Wyndham Championship.

Trying to become the second player this month to break 60 on the PGA Tour, the 21-year-old South Korean player slid a 50-foot birdie putt by the right edge on his final hole — the par-4 ninth. He drove into the left rough, costing himself a clean shot at the front pin position.

Jim Furyk shot the first 58 in PGA Tour history Aug. 7 in the Travelers Championship. Six players, including Furyk, have shot 59.

Kim eagled the par-5 fifth, hitting a 347-yard drive and a 170-yard approach to 10 feet. He made the last of his 10 birdies on the par-4 eighth, holing another 10-footer. Kim played his opening nine in 6-under 29, and also birdied the par-4 second — making another 10-footer.

Kim had a 12-under 128 total for a two-stroke lead over Furyk (64), Lucas Glover (61), Kevin Na (67) and Japan's Hideki Matsuyama (64). Glover also missed a chance for 59 — and 60 — when he closed with a bogey on the par-4 18th.
