If Woo Kim, South Korea, corded a 66 under the age of five to lead after the third round of the RBC inheritance with Tommy Fleetwood three shooting.
Kim enters the final round at Harbor Town Golf Links on 15-Under 198, a clear from the American duo Justin Thomas and Andrew Novak.
Thomas, who posted a 61 in the opening round, started the day with an advantage with two strokes but could only mix four birdies with two Bogeys in a 69 less than two, while Novak equaled Kim 66.
Kim, 29, aims at his fifth victory of the PGA Tour, but his first in more than two years, although he could be left to the height of his only Bogey of the day in the 18th where Thomas, who was in the last twinning with him, made a birdie.
Thomas received a penalty on the second hole by five, when he made the ball move in a waste bunker, although he still managed to recover a peer.
Maverick McNealy (65) is fourth at 13 sous, while Brian Harman (66) and Fleetwood in England (68) are tied in fifth at 12 years.
Fleetwood was only an advance when he made his second birdie of the day at the fifth, but Bogeys in the seventh and 10th blocked his progress, although he managed to play the last eight holes in two under the Birdies in the 11th and 16th.
The defending champion Scottie Scheffler pulled 68, going to 11 sous and equally for seventh place with Russell Henley (70).
