Meanwhile, Thailand’s Chorphaka Jaengkit won the Decatur-Forsyth Classic on Sunday for her first Symetra Tour title, beating Tiffany Chan by a stroke.
Jaengkit closed with a 2-under 70 for a 12-under 204 total at Hickory Point. The 24-year-old former Grand Canyon University player made a 35-foot birdie putt on 16 to take the lead and saved par from 5 feet on 17 to maintain a one-shot advantage. She hit her approach on 18 to 10 feet and twoputted for par.
Playing her sixth career tour event, Jaengkit earned $19,500 to jump from 131st to 16th on the money list with $20,276. The final top 10 will earn LPGA Tour cards.
Chan finished her 63 before Jaengkit teed off.
