First-round leader Carolyn Barbee of Cartersville finished eighth overall at 230 while Kaley Branton, also of Cartersville, was ninth at 231.
Kathryn Fowler of Americus claimed the tournament title after carding three birdies over the last six holes to post a final-round 76 to win by one stroke over second-round leader Sarah Butts of Carrollton at The Manor Golf and Country Club.
Fowler finished the 54-hole championship at 9-over-par 225, while Butts, who posted a final-round 79, finished at 226.
Barbee said she realized some of her goals at the tournament even though she didn't take home its trophy.
"The first day, obviously, l came out with even par and was really happy with that," she said. "On the second day I shot an 81 but I had started out slowly and to finish with an 81 gave me confidence."
She improved her score to a 77 on Wednesday but that wasn't a strong enough score to let her make up ground on the leaders.
Barbee said the tournament offered stiff competition close to home.
"It was a good field with a lot of competition," she said. "When I signed up, my intention was to play my own game and shoot a good score. I did that."
Barbee, who played at Woodland High and will be a junior at Boston College, said she has signed up for a number of tournaments this summer in hopes of keeping her game tournament ready for when she returns to college in the fall.
Branton, a Cass graduate who recently graduated from Troy State University, said she enjoyed competing but wanted a higher finish.
"I didn't do my best -- I couldn't make any putts," she said.
Branton said the tournament still was fun. "I gave it a try," she said. "I haven't (signed up for any more tournaments) yet. I probably will, but I'm not sure which ones yet."
Fowler, a rising sophomore on the golf team at Ole Miss, trailed Butts by three strokes going into the final round, and actually lost ground over the front nine with three bogeys and a triple bogey on No. 5 (410 yards). After beginning the round 6-over-par for the Championship, she turned at 11-over. Butts, meanwhile, turned at 6-over for the Championship to maintain a five stroke lead with nine holes to play.
Butts' biggest trouble came on No. 10, which she triple-bogeyed. She stayed steady with pars on seven of the final eight holes, but a bogey on the 138-yard, par-3 16th proved to be the difference in the final standings, as she finished at 10-over. At the same time, Fowler was making a late charge - after getting to 12-over with a bogey on the par-3 12th, she went on to birdie 13 (457 yards), 16 and 17 to get back to nine-over and edge past Butts for the victory.
Reigning GSGA Senior Women's Player of the Year Brenda Pictor of Marietta moved up two spots in the final standings to finish third, just two strokes back at 227. A triple-bogey on the 373-yard 15th hole proved to be the difference on her scorecard, as she finished with a final-round 76.
Caitlin Watts of LaGrange finished fourth at 228. The trio of Dayana Marquez of Atlanta, Kayla Jones of Alpharetta and Lauren Court of Lawrenceville all tied for fifth and shared top honors in the first flight with a tournament total 229.
Amelia Hill of St. Simons Island finished out the top 10 with a 234.
