"We had a better plan today," said LSU head coach Smoke Laval. "It was a little bit of a wakeup call yesterday."
The Tigers (5-1) managed 10 hits on Friday, but Gamecock pitching registered 13 strikeouts, a concern for Laval.
"It was a bit of a disappointment yesterday," Laval said. "But that's not taking anything away from their (JSU) pitching."
There were few questions on offense Saturday. After Jacksonville State (1-2) took a 1-0 lead in the top of the first on a solo home run by Robb Goodson, the Tigers responded with five runs in the bottom of the second opening the floodgates.
"We hit the ball pretty good today," Laval said. "But which guys will show up tomorrow is the question."
Lane Mestepey (2-0) earned the victory throwing six complete innings, in which he allowed one run on six hits with four strikeouts and a pair of walks.
"I got it going after the first inning," Mestepey said. "My location was better. I can only go out and try to get better. That is all you can ask for."
In only his second start since the 2002 season, Mestepey seemed to be back to his old ways, settling into his role as LSU's dominant hurler.
"Mestepey was close to his old self," Laval said. "About his 18th to 24th pitch he seemed to find it."
Leading 5-1, the Tigers surged for four more runs in the fifth, added another in the sixth before capping the victory with a five-spot in the seventh.
Danny Andres (0-1) took the loss for the Gamecocks. In four innings, Andres gave up five runs, three earned, on six hits and did not log a strikeout.
Collin Smith and Will Harris closed things out on the hill for LSU. Smith pitched two innings in which he gave up an earned run on one hit with a strikeout. Harris worked the final frame striking out one.
The series concludes today with the first pitch slated for noon. LSU looks for the sweep sending freshman lefthander Clay Dirks (0-0, 4.76) to the mound.
