Freshman right-hander Louis Coleman (2-0) won his second straight start Tuesday, going six strong innings and allowing two runs on four hits. Coleman walked one and struck out six while finishing with 85 pitches.
"I started out well then started to get the ball up towards the end of the game," said Coleman. "I'm learning to keep the ball down. In high school, I was trying to get everybody out, but here you have eight guys behind you who can play."
"(Coleman) seems to get better with every outing, and that's good," said LSU coach Smoke Laval. "He still struggles at little bit with a runner at second base, but the impressive part is he improves with every single out."
Left fielder Steven Waguespack went 3-for-4, and catcher Matt Liuzza collected two hits to lift his batting average to .458.
SLU starter Jason Waguespack (0-1) suffered the loss, allowing seven runs (one earned) on nine hits in 4.1 innings.
After falling behind 1-0 on a two-out, solo homer by Tony Suarez, LSU responded with six unearned runs -- all with two outs -- in the bottom of the second.
A heavy mist blanketed the field for most of the game and it played havoc with ground balls in the second frame.
Jason Waguespack easily retired the first two batters of the inning. Liuzza then smashed a ground ball to third that caromed into left field for a base hit. Will Harris and J.T. Wise were able to reach on errors by third baseman Bryan Frichter and shortstop Richard Imhoff, respectively. Both were sharp grounders that were misplayed in the wet conditions.
Waguespack suddenly found himself in a jam tied at 1-1 with a pair of runners on. Second baseman Jason Ogata then lined a two-run double into the left field gap followed by a RBI single from centerfielder Bruce Sprowl to make it 4-1.
Shortstop Michael Hollander closed the two-out scoring spree with a two-run homer over the left field wall. It was the fourth by the Tigers this season and the second of Hollander's career.
In the fifth, LSU brought in another run on Liuzza's RBI double, scoring Steven Waguespack who tripled with one out.
Coleman gave way to senior Chase Dardar to start the seventh with the Tigers holding a 7-2 advantage.
Dardar and fellow right-hander Edgar Ramirez worked the final three innings, limiting the Lions to a run on three hits. LSU finished with 11 strikeouts in the game, including two by Ramirez in the ninth.
