DUBLIN, Ohio (AP) — J.T. Poston was tied for the lead Sunday morning when three swings with a wedge changed everything at the Memorial. He ran off three straight birdies with superb shots, finished off the rain-delayed third round with a 3-under 69 and built a four-shot lead.Poston, who was at 12-under 204, had a few hours before starting the final round as he goes after the biggest win of his career.Ryan Gerard fell back with a series of pars and two bogeys when the third round resumed on a much softer Muirfield Village course. He had to settle for a 72 and was four behind.Sam Burns got swallowed up by the rough on the par-5 11th for a double bogey, rallied with a pair of birdies and was five shots behind.Scottie Scheffler tried to get closer to the lead, but the best he could do was a 68 that still left him nine shots behind with 18 holes to play. He was trying to join Tiger Woods as the only players to win the Memorial three years in a row.

Scheffler’s hopes took a bad turn Saturday, right before a second storm delay halted play. He had played a six-hole stretch around the turn in 5-under par and had a long eagle putt before he three-putted for par, took bogey on the par-3 12th and put his tee shot in the water for bogey on the 14th.
