Senior Celeste Troche, who had an uncharacteristic 81 on Wednesday, bounced back with a bogey-free 71 on Thursday. She finished one-under-par with a birdie and 17 pars. Troche is tied for 16th individually with a 228 total.
Senior Diane Ramage shot a 74 and is making a run to be Auburn's top individual competitor at 11-over-par, which ties her for 10th place at 227.
"We just couldn't seem to get our engine started," Auburn coach Kim Evans said. "We have been unable to get four players playing well at the same time. Celeste had a great sub-par round while Diana had another good effort. We are going to come out in the final round and give it all we have."
Senior Danielle Downey shot a 77 on Thursday and dropped back to eighth place at 226, six strokes off the lead shared by Florida's Andrea Vander Lende and Southern Cal's Mikaela Parmlid.
Sophomore Kingsley Barrett's 78 round was the fourth and final score the Tigers counted in round three. She is tied for 115th place at 250. Freshman Maria Martinez shot an 81 and is in a tie for 86th place at 242.
Auburn will have to make a strong charge on Friday to match last year's second place finish.
