HILTON HEAD ISLAND, S.C. (AP) - Carl Pettersson birdied five straight holes on the front nine and finished with a birdie on the 18th hole for a 5-under 66 and a one-stroke lead over Colt Knost on Saturday after the third round of the RBC Heritage.
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-footer for birdie on Harbour Town Golf Links signature closing hole. He had a 12-under 201 total
Knost's roller coaster of a round included an eagle on No. 2 and several missed fairways on the tight holes. Still, he kept close enough with a 69.
Zach Johnson, the 2007 Masters winner, shot a 66 to move to third at 8 under. Two-time RBC Heritage champion Boo Weekley had a 70 and was 7 under. Defending champ Brandt Snedeker (69), Kevin Na (70) and Robert Garrigus (70) were next at 6 under.
World No. 1 Luke Donald failed to make a move toward keeping the top spot, his even-par 71 leaving him at 2 over and tied for 52nd. Donald needs to finish eighth or better to fend off No. 2 Rory McIlroy, who like Masters champion Bubba Watson and most other top players, took the week off.
