Played at the beautiful Oceanside Country Club near Daytona Beach, Fla., Aree made a pair of 25-foot putts, one for birdie and the other to save bogey, to keep her sister from catching her.
For Aree, who is ranked No. 1 in the Golfweek/Titleist Amateur Rankings, it has been a incredible run. She took first place at the Harder Hall Invitational, was co-medalist at the Futures Tour Qualifying School tournament, and won the individual title at the World Team Amateur Championship.
For Naree, who was the defending champion, it was the second time recently to finish behind her sister, as she also placed second to Aree at the Harder Hall Invitational.
Robin Burke shot a final-round 73 to finish alone in third and third-round leader Laura Myerscoughs struggled in with a 78, good for fourth place.
