Nelson, however, may not be able to make up the deficit. If thunderstorms roll in overnight as forecasted, the already-soaked Tiffany Greens course could be unplayable for Sunday's final round.
'I hope we have a chance to play, but I can't see this golf course taking much more rain,' said Nelson, who shot a 66 on Saturday for a 9-under 135 total. 'It gets to the point where two guys can hit a shot from the same place and the ball's going to slip and slide and do different things.'
Lietzke started the day one stroke off the lead. He had eight birdies and 10 pars Saturday. His most important par came on the dangerous 165-yard, par-3 15th, a hole with a narrow green guarded by sand and water that Bruce Fleisher, Walter Hall and Hale Irwin all double-bogeyed.
Hall and Irwin shot 68s and were four strokes off the pace along with Tom Wargo. Fleisher and Tom Purtzer were another stroke back after their second straight 69s.
John Schroeder, who holed out twice from off the green on Friday, started the day with an eagle on the 510-yard, par-5 10th. But he and defending champion Ed Dougherty, who each shot 68 on Friday to share the first-round lead with Bob Eastwood, both double-bogeyed the par-3 10th and finished with a 74. Eastwood had a 75.
