Memphis - Ben Crane has completed a one-under par third-round 69 on Sunday to take a three-shot lead into the afternoon's final round of the US PGA Tour's St. Jude Classic.
Crane was facing a marathon march in his quest for a fifth tour win -- and his first since 2011 -- thanks to weather delays on each of the first three days of the $5.8 million tournament.
Crane had two birdies and one bogey in his third-round for a 13-under total of 197 through 54 holes, and the final round began shortly after the third concluded.
Fellow American Troy Merritt posted a third-round 67 for 200, with Brian Harman on 201 after a 67.
Five-time major champion Phil Mickelson, seeking to build momentum heading into next week's US Open at Pinehurst, fired a bogey-free 67 that left him tied with Matt Every (65) on 202.
The 43-year-old American left-hander, a five-time major champion, can complete a career grand slam with a victory next week.
But he has a history of heartache at the event, having finished second a record six times, the first of those coming at Pinehurst in 1999.
In addition, Mickelson has not had a top-10 finish this year in 13 starts.
