Mike Weir and Brett Wetterich were tied for the lead at 14-under when the third round of the Honda Classic was halted because of darkness. Weir completed 10 holes and Wetterich 11.
Twenty-five others, including Fred Couples and Phil Mickelson, were within four strokes of the lead.
Play will resume Sunday morning, and the final round will start shortly after the third round is completed.
Heavy rain fell on the course Thursday, leaving dozens of players with more than 18 holes to play Friday and Saturday.
The weather also left the course with soft greens that yielded several low scores. Scoring was made even easier Saturday when Heron Bay's lone defender ' strong, steady wind ' took a day off.
Only five of 71 players were over par in the third round when it was suspended at 6:30 p.m. EST.
Second-round leader John Riegger, 1997 U.S. Amateur champion Matt Kuchar, rookie Stephen Gangluff and 1988 Honda Classic champion Joey Sindelar were tied at 13-under.
Kuchar (6-under 66) and Gangluff (65) were among the 21 golfers who completed the third round.
Riegger had a share of the lead after eight holes, but his tee shot on the tough, par-4 No. 18 found the water. He bogeyed the hole to fall a stroke behind of the leaders.
Weir, a left-handed Canadian, shot a 65 in the second round and was one stroke behind Riegger as the third round began Saturday afternoon. Playing in the same group as Riegger, Weir took the lead after consecutive birdies on Nos. 11 and 12.
Riegger, winless in 115 tour events and still looking for his first top-10 finish in five full seasons on the PGA Tour, pulled even with a birdie at No. 14.
Defending champion Jesper Parnevik, 17-year-old Ty Tryon and Southern sensation Boo Weekley missed the cut, which tied the tournament record at 4-under 140.
Wetterich earned his tour card at qualifying school in 2001, but missed most of last season with a wrist injury. He received a medical extension that allows him to compete on tour this year, but he must make $383,901 in his first 19 events to become exempt for the rest of the season.
Wetterich missed the cut in each of the five events he entered so far.
