Stephanie Meadow continued her solid showing at the LPGA Drive On Championship with a third round one-under 71 that moved her to one-under overall.
Meadow carded three birdies and a couple of bogeys - one of which came, frustratingly, on her last hole - on the Reynolds Lake Oconee course.
Leona Maguire's one-over 73 left her on three over for tournament. The Cavan woman shot four birdies and three bogeys but came unstuck on the par-four ninth, where she coughed up a double bogey.
American Ally McDonald goes into the final day at the top of the leaderboard after shooting a 69 that leaves her on 13 under, one clear of Bianca Pagdanganan of the Phillipines.
McDonald was playing alongside Pagdanganan and five-time Tour winner Danielle Kang, swapping the lead with both following a patchy start. Birdies at the fifth, eighth and ninth settled McDonald however and the 28-year-old is now in pole position to earn the first Tour victory of her career.
