She made the 72-hole cut with a shot to spare but Stephanie Meadow needs a round in the 60s to win her card in Sunday's final round of the LPGA Final Qualifying Tournament in Florida.
Two bogeys and just one birdie in one over 73 on the Jones course at LPGA International in Daytona Beach saw the Jordanstown talent up fall seven spots to tied 50th on one over in the race for just 20 cards (no ties).
With 22 players on four under or better, it looks likely she will need at least a 66 in round five to finish in the top 20 and win membership in category 12.
Those that finish from 21st to 45th (including ties) will earn membership in category 17.
American Jaye Marie Green shot a 70 on the Hills course on Saturday to grab a two shot lead on 15-under, 273 from Iceland’s Olafia Kristinsdottir, who carded a 68 on the Jones course.
While world No 1 amateur Leona Maguire opted not to compete in favour or completing her degree at Duke by May 2018, No 2 Bronte Law shot a 70 and is tied for 30th on two under.
“I created a lot of chances today, but I wasn’t really making anything,” said Law, who made three birdies against one bogey.
“Towards the end, I made two really good birdies to put myself right back in there. My putts on 17 and 18 just slid by. Overall, I’m pretty pleased with my round and I’m hoping those putts are going to go in tomorrow.”
Law, who is the No. 2 ranked amateur in the world and the reigning ANNIKA Award winner, posted rounds of 75-68-73-70.
“This is the opportunity I’ve been waiting on for a long time,” said Law. “I was hoping to play a little better as I was playing very well coming in.
“My swing feels good and I’m really hoping that I get that low round tomorrow because I’m really looking to get that card.”
