GAINESVILLE, Fla. — South Florida edged the Georgia Southern Eagles in Gainesville Regional opener, winning 1-0 in eight innings on Friday. Sarah Purvis tossed seven innings of shutout ball to send the game into extra innings for the Eagles, but USF struck out 18 batters on the day and converted a leadoff, bunt single in the eighth into an RBI and the game-winning run. “That was a good game,” GSU coach Annie Smith said.
