The winner of the Zurich Classic of New Orleans will be crowned on Monday after the tournament was pushed into a fifth day due to storms.
Brian Stuard and Jhonattan Vegas shared the lead on 13-under-par when play was suspended after just over two-and-a-half hours from the opening tee.
Nobody in the 82-man field were able to complete their third rounds, and now the tournament has been reduced to a 54-hole event.
Stuard and Vegas got through five holes before play was suspended, and with just five strokes separating the top 23 players, the final day could provide an exciting finish.
Bobby Wyatt sits just one shot off the pace after an impressive front nine, which included an eagle on the second hole and four birdies, three of which came consecutively from the sixth hole.
Jamie Lovemark, who shared the clubhouse lead after the second round, dropped two strokes behind in five holes.
