HILTON HEAD ISLAND, S.C. (AP) - Carl Pettersson had a run of five straight birdies on the front nine and finished with a birdie on the 18th hole to shoot a 66 and take a one-stroke lead over Colt Knost after the third round of the RBC Heritage on Saturday.
Pettersson held a three-stroke lead through 10 holes, yet was tied with Knost after the 15th. Pettersson moved in front with the round's final putt, an 8-foot birdie on Harbour Town Golf Links signature closing hole.
Knost's roller coaster of a round included an eagle on No. 2 and several missed fairways on the tight holes of Harbour Town Golf Links. Still, he kept close enough with a 69. He'll be paired with Pettersson again Sunday in the chase for his first PGA Tour win.
