World No. 1 Scottie Scheffler strikes again.
The Masters winner fired a low-round 8-under-par 63 to shoot into the lead by a stroke at the RBC Heritage on Saturday at Hilton Head Island, S.C.
Scheffler was tied for 10th entering the third round.
Scheffler sits at 16-under 197, one stroke ahead of Sepp Straka (third-round 67). Collin Morikawa, who played with Scheffler in the final pairing at Augusta, Ga., last week, is third at 14 under after a 68.
Three golfers are three shots off the lead in a tie for fourth.
Scheffler turned in a bogey-free round, carding five birdies on the front nine and another three coming in, including No. 18.
He is gunning for his fourth victory in his past five tournaments played.
The next-lowest scores of Saturday's round were two 65s posted by Adam Schenk and Alejandro Tosti.
