It looked like Tulane's recent winning ways over LSU would continue on Wednesday when the Green Wave jumped out to 4-0 lead. But LSU scored the next 10 runs to win 10-4 over their old in-state rivals.
The Tigers fell behind in the 3rd inning, but LSU jumped ahead with a 5-run 5th inning.
Daniel Cabrera, who had four hits on the night, gave the Tigers the lead with an RBI single through the right side of the infield. Zach Watson gave LSU a cushion with a two-run single to left field.
Watson had three hits, including a double, three runs scored and 3 RBI.
Nick Storz made his collegiate debut and threw one inning. The big right-hander hit the first two batters he faced in the first inning, but got out of the inning unscathed with a couple of ground outs and a strikeout.
AJ Labas got knocked around for three runs in the 4th inning, which allowed the Green Wave to take a 4-0 lead. But Labas was named the winning pitcher, as his other three innings were scoreless.
Devin Fontenot and Matthew Beck were next out of the bullpen and both of them struck out the side.
With the win, LSU gets its first win over the Green Wave since 2015. The Tigers are now 14-7 and will visit Vanderbilt for a weekend series that starts Friday in Nashville. The Commodores swept Mississippi State last weekend.
