Justin Rose shot a third-round 70 to move within three shots of the lead at the Memorial Tournament in Dublin, Ohio.
The Englishman was in a five-way tie for second on five under at the demanding Muirfield Village Golf Club after carding three birdies and an eagle.
It marked a good recovery after a second-round 70, but there was still work to do to catch leader Matthew Goggin.
The Australian, who started the day tied for the lead with Kenny Perry, carded a one-under-par 71 to end the day on eight-under 208.
Perry was back level with Rose, Mike Weir, Matt Kuchar and Jerry Kelly on 211.
Goggin built a three-shot lead with two birdies in the first three holes, before the threat of lightning stopped play for two hours, 25 minutes.
The delay seemed to hurt his momentum, as he made just one birdie in the remainder of the round - but not that they were easy to come by on a course with thick rough and slick greens.
But he kept his mistakes to a minimum, making only two bogeys, to end the day in a great position to win the Jack Nicklaus-hosted event.
