Lightning forced the players off the course at 7:30 p.m. Friday, half an hour after play resumed following a three-hour delay because of lightning and rain. Heavy rain followed, dropping a little more than a half-inch in 20 minutes.
More rain was expected Saturday afternoon, a daunting prospect for the tournament that has lost 12 hours of daylight to the storms that have drenched the clay-base layout with more than 2 inches of rain in two days.
"If we get any rain during the day tomorrow, we're at what they call field capacity," Carman said. "The sponge is full of water."
Jerry Kelly had the lead at 11 under, a stroke ahead of Camilo Villegas, Tim Herron, Martin Laird and Nathan Green, with 76 players
- including Canadian star Mike Weir and first-round co-leader Kevin Na - still waiting to start the second round.
Kelly shot a 7-under 65 in perfect scoring conditions at the completion of the first round and birdied the last of his 15 holes in the second to pull ahead.
Villegas, tied for the first-round lead with Na after a 63 in the morning, also had three holes to play. Herron had two to go, Laird one and Green six.
"It would have been nice to get the whole round in and sleep in until 1," said Herron, set to resume play early Saturday.
Na and Bob Estes were 9 under. Estes had five holes left.
The 42-year-old Kelly, the New Orleans winner in April coming off a third-place finish last week in Milwaukee in his home-state event, had seven birdies in a nine-hole stretch in the first round on the vulnerable course.
"You can get after it," Kelly said.
But only if it's dry enough to play.
"Our regulations dictate that we're playing 72 holes by the end of Monday, then the option would be to go back to 54 holes," Carman said. "But we're pretty much regulated to try and get 72 holes in by the end of the day Monday."
The event could possibly stretch to Tuesday.
"Again, according to the regulations, if you're playing the final round and half the field finishes on Monday night, that would force you to go into Tuesday to finish that round. That's pretty much the only way we could go to Tuesday."
