LSU lost its starting pitcher in the first inning of its weekend series with Missouri in Columbia Friday night.
The eighth-ranked Tigers pulled Zack Hess from the series opener after 13 pitches with a groin injury.
But, the LSU bats battled through a wild game, finally edging those other Tigers, 12-11, in 10 innings.
Missouri scored six runs in the first inning to take a six-three lead. LSU rallied for five runs in the third inning, and three more in the fourth inning.
But despite an 11-6 lead, Missouri tied the game.
An Antoine Duplantis ground ball scored Josh Smith from third base for the winning run.
Brandt Broussard and Cade Beloso each drove in three runs. Todd Peterson was the winning pitcher, striking out five in three innings and Devin Fontenot earned the save, his third of the year.
