MESA, Ariz. (AP) Hannah O'Sullivan moved into position to become the youngest winner in Symetra Tour history, shooting a 7-under 65 on Saturday to open a four-stroke lead in the season-opening Gateway Classic.
The 16-year-old O'Sullivan, a junior at nearby Chandler Hamilton, had eight birdies and a bogey to reach 12-under 132 at Longbow. She opened with a bogey-free 69 on Friday.
LPGA Tour star Cristie Kerr is the youngest winner in tour history, taking the 1995 Ironwood Futures Classic in Gainesville, Florida, at 17.
O'Sullivan has verbally committed to play at the University of Southern California. She was a semifinalist last year in the U.S. Women's Amateur and played on the winning U.S. team in the Junior Ryder Cup in Scotland. She won the Arizona high school titles in 2012 and 2013.
First-round leader Haley Italia was second after a 71.
