LSU's Ross kept the Vanderbilt bats in check most of the night as VU scored three runs in the third and two in the ninth but were held scoreless in the remaining seven frames.
Trailing 7-3 with two outs in the bottom of the ninth, the ‘Dores made things interesting when Aaron Westlake was at second base after a leadoff single to start the inning. After LSU recorded the next two outs, Joe Loftus singled up the middle to plate Westlake from second to make it a 7-4 game.
In the very next at-bat, Bryan Johns roped a double down the left-field line off Tiger closer Matty Ott, scoring Loftus from first to make it 7-5, before Mike Yastrzenski struck out to end the game.
LSU got on the board in the top of the first when they scored three runs on four hits while sending seven batters to the plate. The Tigers got RBI-singles in the inning from Blake Dean and Leon Landry while Austin Nola drove in the other run with a double to left-field.
The Commodores answered the Tigers call in the second inning when they scored three runs on three hits, led by Yastrzemski's two-run blast over the right field wall. Loftus started the offensive attack in the second when he hit a one-out double to left-center before scoring VU's first run of the game on a RBI-single through the left side by Connor Harrell. Following Harrell's single, Yastrzemski drove Ross' very next pitch into the first row of trees beyond the right field wall for his second homer of the year and tying the game at three.
LSU retook the lead in the third when Micah Gibbs connected on a two-out solo home run to right field, giving the Tigers a 4-3 lead.
The Tigers had a chance to add to its lead in the fourth when they had runners on first and third with one out before Taylor Hill got Mason Katz to ground into an inning-ending 4-6-3 double play to end the threat.
LSU extended its lead in the fifth when Tyler Hanover scored on a passed ball, giving LSU a 5-3 lead. Hanover reached base by doubling to left-center and then advanced to third on an infield groundout by Dean.
The Tigers plated two more runs in the sixth when they tallied two hits and took advantage of a Vanderbilt fielding error to go up 7-3.
Taylor Hill (5-5) allowed five runs scattering nine hits in 4.2 innings with two walks and three strikeouts in the loss.
