The Tigers (18-5) posted their second consecutive come-from-behind victory and have now won the last 10 meetings against SLU. The Lions (11-11) issued eight walks Wednesday and committed two critical errors.

Mayer's single came after a 35-minute rain delay, in which play was suspended at 9:07 p.m. Left fielder Bruce Sprowl added two hits and secured the victory with a running catch to end the game with a runner on.
Right-hander Edgar Ramirez (1-0) worked four innings of scoreless relief to record his first career victory. Ramirez limited SLU to one hit, walked two and struck out four.
Sprowl gave LSU an early lead in the second on a double to the right field wall, scoring catcher Robert Lara who reached on a walk. Sprowl was able to advance to third on the throw from the outfield, and one batter later shortstop Michael Hollander drove him in on a sacrifice fly.
However, the Tigers' 2-0 lead quickly turned into a 4-2 deficit as the Lions batted around and used the bunt to their advantage off starter Michael Bonura in the third. After catcher Ricky Newman worked a leadoff walk, third baseman Bryan Frichter reached on third baseman Will Harris' throwing error on a bunt.
Right fielder Ty Summerlin then caught Harris off guard with another bunt, which loaded the bases with no outs. Shortstop Richard Imhoff brought in SLU's first run with a sharp single to right.
Bonura's outing ended when designated hitter Jason Waguespack -- the Lions' leading hitter -- tied the game with a suicide bunt in front of the mound.
Ramirez inherited a bases-loaded, no-out situation and immediately surrendered the lead with a four-pitch walk to left fielder Ryan Spencer. The right-hander worked his way out of the inning but not before issuing another run-scoring walk to first baseman Wade Miley.
A steady rain began to fall in the fifth, as LSU recovered to tie the game at 4-4 one frame later. Right fielder Quinn Stewart and Mayer each singled to start the sixth. Following Harris' sacrifice bunt, second baseman Nick Pontiff rolled a grounder underneath Miley's glove at first.
Stewart and Mayer scored on the error as the rains continued. Officials soon suspended play just before the first pitch was thrown in the seventh.
LSU seemed rejuvenated when the game resumed at 9:42 p.m. Mayer greeted southpaw reliever Matt Greenwich, an LSU transfer, with the go-ahead single in the seventh. The sophomore drove in pinch hitter Jarred Bogany who reached on one of Greenwich's two walks.
Meanwhile, Ramirez retired 10 of the last 11 batters he faced before giving way to right-hander Darryl Shaffer to start the bottom of the seventh. Shaffer survived a two-on, one-out situation in the eighth on a brilliant play by Lara.
Shaffer recorded a strikeout with a runner attempting to steal second. Hollander then cut off Lara's throw to second and fired back in to the freshman who blocked the plate to keep the tying run from scoring.
Shaffer registered a scoreless ninth to pick up his team-leading second save of the season.
