The Chanticleers got things started in the top of the second when junior designated hitter G. K Young blasted his 17th home run over the left field fence to take a 1-0 lead.
LSU battled back as junior centerfielder Jake Fraley connected on a single and Kramer Robertson got aboard after being hit by a pitch, but the runs themselves were delivered once again from sophomore first baseman Greg Deichmann.
The three-run bomb was lifted to right field and electrified Alex Box Stadium as LSU took a 3-1 lead in the fourth inning.
But the Tigers would not maintain their lead over the Chanticleers for long.
