Sizzling Scottie Scheffler fires 63, up by 1 at RBC Heritage - ESPN

HILTON HEAD ISLAND, S.C. — Masters champion Scottie Scheffler was relentless as ever Saturday with another bogey-free round at the RBC Heritage, an 8-under 63 that gave him a 1-shot lead and left him one round from joining some rare company.

Not since Bernhard Langer in 1985 has a Masters champion won the following week on the PGA Tour at Harbour Town. The only other Masters champion to win the next week was Gary Player in 1978 at the Tournament of Champions.

And the last player to win a major and then win on the PGA Tour the following week was Tiger Woods in 2006 (PGA Championship, WGC-Bridgestone Invitational).

«I think when I'm playing my best, sometimes it feels like I'm competing against myself a little bit out there, trying to keep pushing and stay as focused as I can,» said Scheffler, who has converted each of his past three outright 54-hole leads on tour.

«At the end of the day, we're out here competing against the best players in the world. I love competing against these guys, and I'm looking forward to the challenge of coming out and competing tomorrow.»

Scheffler was at 16-under 197. Sepp Straka made a 15-foot birdie putt on the last hole for a 65 to get within 1 shot. They will be in the final group Sunday, with a different wind and thunderstorms in the forecast.

Two-time major champion Collin Morikawa made one mistake late, coming up short of the 16th green and missing a 10-foot par putt. He had a 68 and was 2 shots behind. Masters runner-up Ludvig Åberg was among those 3 shots back.

All of them are chasing the No. 1 player in the world amid a dominant stretch of golf not seen since Woods in his prime.

Scheffler has gone 51 consecutive holes at par or better at Harbour Town. He posted his 39th consecutive
