PRATTVILLE - LPGA players endured a frustrating day at the Senator course on Saturday as multiple weather delays saw the leaders complete just four holes of the LPGA Classic third round. American Austin Ernst, who started the third round a shot behind 36-hole leader Tseng Ya-ni, had edged ahead through four holes when darkness halted play. Ernst birdied the par-three second hole to pull level with former world number one Tseng, who fell back with a bogey at the par-four fourth. But mostly Saturday it was a waiting game as multiple weather delays halted play for a total of five hours. The event was already behind schedule, after a weather delay on Friday saw 31 players have to return early Saturday to complete the second round. "It's going to be a marathon," said Ernst.
