Officials stopped play at 1:18 PM EDT and the round was abandoned at 5:45 PM after a half-inch of rain inundated the course. Only five of 61 players completed their third round and 10 had not yet started their rounds.
Players will return to the course 9:00 AM Sunday to finish the third round with the final round slated to begin at 2:00 PM.
Zach Johnson, the leader after both the first and second rounds, was on his way to the practice range when the horn sounded. He carded a pair of 65s to take the midway lead at 14-under-par 130. Johnson, who earned the final spot in the field thanks to winning a playoff in the Monday qualifying, is ahead by four over Tjaart van der Walt.
'Momentum will be a big key when we get started tomorrow,' said Johnson. 'We still have half the tournament to play and that's a lot of golf. Anything can happen out here, especially on a difficult course like this. Anybody can get off to a good start and just ride that the whole day.'
Johnson, who has conditional status on the Nationwide Tour, was once in the position of 36-hole leader on tour. At the 2000 Tri-Cities Open, Johnson had a one-shot lead at the halfway point but struggled on the weekend and tied for 25th.
'Yes, I'd rather have the lead but I'm not sure you can ever be comfortable with the lead on this golf course,' said Johnson. 'Momentum will be a big key when we can back on the course. It'll be important to get off to a good start and try to maintain that. I think there is more incentive to hit the fairways now because the greens will be more receptive because of the rain.'
Lucas Glover and Ted Purdy are tied for third at 8-under-par 136.
D.A. Points was one of the 10 players to complete his round on Saturday. He posted a 5-under 67 and is tied for fifth at 6-under par. Jeff Gallagher is 6-under with one hole to play, Scott Gump, Mark Hensby and Mike Grob are at the score on the front nine and Bo Van Pelt has yet to begin his round.
