HILTON HEAD ISLAND, S.C.—Scottie Scheffler is running on fumes after an exhausting Masters victory just four days ago. He hit a shank from a bunker. He nearly lost his mind from mud on his golf ball. And he still managed a 2–under 69 at the RBC Heritage on Thursday.
J.T. Poston set the pace on an idyllic day on Hilton Head Island with nine birdies—six of them in a seven-hole stretch—for a 63 that gave him a two-shot lead over Collin Morikawa and Seamus Power.
