The round was suspended for the day just before 5:30 p.m. CST after a weather delay of nearly 2 1/2 hours. Players were driven back to their holes in the middle of the delay for a scheduled re-start, but the rain continued and they were taken back to the clubhouse.
It is the second week in a row that a PGA Tour event has faced weather problems. Geoff Ogilvy won a Monday finish at the rain-delayed CA Championship.
Just 35 of the 81 players had completed their rounds before play was stopped.
John Senden held the clubhouse lead at 7-under with 66- 209 when play was suspended.
