LPGA Tour rookie Allisen Corpuz has the chance to cap her first season in style after claiming a one-shot lead going into the final round of the penultimate tournament.
Hawaiian Corpuz shot a five-under 65 second round on Saturday to reach 10 under at the storm-shortened Pelican Women's Championship in Florida.
Right behind Corpuz is a group of top contenders, making that one-shot lead feel even smaller.
Maja Stark of Sweden, who earned LPGA Tour membership with a co-sanctioned win in Northern Ireland this summer, had eight birdies at Pelican Golf Club for a 63.
She was tied second along with Lexi Thompson (67) and Maria Fassi of Mexico, who followed her career-best 62 with a hard-earned 69 that left her in position to win for the first time and qualify for the season-ending CME Group Tour Championship.
Nelly Korda (66) and Carlota Ciganda (68) were two shots out of the lead. Twelve players were separated by four shots going into the final round.
Hannah Green was the only Australian to make the cut and was tied 20th at four under after a 69. Steph Kyriacou and Sarah Kemp both missed out by a shot despite shooting 68s.
Corpuz, twice an All-American while at Southern California and a Curtis Cup player, didn't make a bogey until her final hole at the par-3 ninth.
The tournament has been cut short to 54 holes because of heavy rain from Tropical Storm Nicole that washed out the opening round.
The Pelican Women's Championship is the final event for the leading 60 players in the CME Race to the Globe to qualify for the final event.
Fassi is at No. 72 and needs a strong week to advance.
But so many players are in contention.
About the only one missing was Lydia Ko, who played her final 11 holes in even par and had to settle for a 69. That left her seven shots behind - with 26 players ahead of her. Ko could have wrapped up LPGA Player of the Year with a victory.
