Jason Bohn shot an 8-under 64 to take an early lead at the U.S. PGA Tour's True South Classic before heavy rain halted play on Thursday.
Luke Guthrie, in just his third professional tournament, opened with a 65. He finished last week's John Deere Classic tied for fifth.
J.J. Killeen, Steve Lowery, Ryuji Imada, Jason Gore and Willie Wood share a tie for third, two shots behind Bohn.
After a week of rain, Annandale Golf Club's fairways were soft with areas of standing water. Players were allowed to lift, clean and place balls in the fairway, helping scores stay low.
''There was very little roll (in the fairways), but that makes the fairways wider,'' Bohn said. ''You can play more aggressively off the tee — use drivers where you might use a 3-wood.''
With many of the big names playing in the British Open this week, an unfamiliar collection of players was at the top of the leaderboard. J.J. Killeen, Steve Lowery, Ryuji Imada, Jason Gore and Willie Wood shared a tie for third, two shots behind Bohn.
Killeen, Imada and Gore have yet to win on the Tour, while both Lowery and Wood have won at Annandale.
Guthrie has had some early success on the Tour, starting his career with a top-20 finish at the St. Jude Classic before another impressive showing at the John Deere.
''I've got some good momentum going,'' Guthrie said. ''I hit some solid putts.''
Bohn's good start gives him some encouragement that his recent slump could be coming to an end.
''I kept telling myself I'm going to play some good rounds,'' Bohn said. ''I've just got to take the bad rounds that I play and make them not so bad.''
Bohn didn't make many mistakes on Thursday, though he did lose his grip on a drive at No. 18, leaving a difficult shot out of a fairway bunker. He recovered for a birdie.
''The one difficult thing we don't really play too much in the humidity,'' Bohn said. ''The warm weather certainly presented itself today. It's tough to keep your hands dry.''
Other than wet hands, Bohn didn't have many complaints. The soft and muddy course was usually forgiving.
''There's no wind, and the greens are very receptive,'' he said. ''The greens are perfect. They're some of the best greens we play on the PGA Tour. ... You've kind of got to take advantage of it.''
Officials expect the first round will resume Friday morning with the second round to follow.
