Scottie Scheffler produced a stunning late birdie burst to capitalise on a mid-round wobble from Ben Griffin and take a one-shot lead into the final round of the Memorial Tournament.
The world No 1, who opened with 13 consecutive pars on Saturday, birdied four of his five holes to post a four-under 68 and card his first bogey-free round ever at Muirfield Village.
The fast finish lifted Scheffler to eight under and one ahead of halfway co-leader Griffin, with the FedExCup leader now in prime position to follow his PGA Championship success with a third PGA Tour win in four starts.
Scheffler will play in the final round alongside Griffin, who briefly went five strokes ahead before four consecutive bogeys around the turn and a dropped shot at the last left him settling for a level-par 72.
