Si Woo Kim shoots 66, holds third-round lead at RBC Heritage

South Korea's Si Woo Kim shot 5-under-par 66 to move into the lead in the RBC Heritage in Saturday's third round as second-round leader Justin Thomas hit rough patches at Hilton Head Island, S.C.

Kim is at 15-under 198, holding a one-shot edge on Thomas and Andrew Novak going into Sunday's final round at Harbour Town Golf Links.

Thomas (69 on Saturday) and Novak (66) both have three sub-70 rounds in the tournament. Maverick McNealy (65) is fourth at 13 under.

Kim, 29, will be aiming for his fifth PGA Tour victory and his first in more than two years. His lead was reduced on the final hole when he had his only bogey on No. 18 while Thomas, who was in the final pairing with him, was notching a birdie.

Brian Harman (66) and England's Tommy Fleetwood (68) are tied for fifth at 12 under.

Defending champion Scottie Scheffler shot 68, moving to 11 under and tied for seventh place with Russell Henley (70).

Thomas held a 36-hole tournament lead for the first time since 2022, up two on Kim and Henley, but he had an eventful third round.

Thomas was assessed a one-stroke penalty on the second hole, when he caused the ball to move in a waste bunker. Still, he ended up with par-5 on the hole.

Later, he hit out of a water hazard on No. 11 and didn't recover as well, taking his first bogey of the round. His bogey on No. 15 dropped him three strokes behind Kim.

Then at par-3 No. 17, Thomas was off the green following his tee shot but he ended up with par.

Novak had a bogey-free round, with two of his five birdies coming on par-3 holes.

McNealy recorded his second 65 in a row, boosted by a 5 under front nine. He birdied all three par-3 layouts during the round.
