Jaclyn Sweeney fired a 5-under 67 on Sunday to win the VisitMesa.com Gateway Classic at Longbow Golf Club.
Sweeney finished her second Symetra Tour victory at 7-under-par 209. She started the round two strokes behind the four leaders.
At the first, Sweeney converted her first birdie effort. She stumbled to a bogey at two, then parred the next six holes.
Sweeney birdied the ninth and 11th. She caught fire down the stretch with three birdies in the final four holes to grab the title.
Alena Sharp, one of the four second-round co-leaders, managed a 1-under 71 to end alone in second at minus-5. Cydney Clanton (70) and second-round co-leader Stephanie Kono (73) shared third at 3-under 213.
Jenny Suh and Tiffany Joh, the other second-round co-leaders struggled to 2- over 74s. They tied for fifth at minus-2 with Jaye Marie Green (72) and Amelia Lewis (73).
The second round was completed earlier Sunday after a frost delay pushed things back on Saturday.
