World number one Scottie Scheffler has continued his stellar run of form by surging into the lead at the Memorial Tournament.
Scheffler entered Saturday's third round trailing Nick Taylor and Ben Griffin by three strokes.
The 28 year old, who is searching for a third victory from his past four tournaments, went bogey free and birdied four holes down the stretch to card a score of four under 68.
He sits one shot ahead of Griffin, while Taylor is two shots further back after they carded 72 and 74 respectively.
Shane Lowry is in tied-seventh place after a frustrating one-over par 73 left him six shots off the pace heading into the final round at Muirfield Village.
The 2019 Open Champion briefly fell back to even par after successive bogeys on 13 and 14 but he did recover down the stretch with birdies on the par-5 15th and the 18th after a superb approach.
Lowry sits with a trio of players on two-under par overall, alongside Patrick Cantlay and Rickie Fowler.
One stroke better are the grouping in tied-fourth, which contains Jordan Spieth, Sepp Straka and US Ryder Cup captain Keegan Bradley.
