Alex Lange's curveball was dominant as it's been all season as the Tigers blanked Auburn 4-0 to move within a half-game of Florida and Mississippi State for first place in the overall standings in the SEC.
Lange threw 118 pitches and went the distance, allowing five hits and striking out nine.
He becomes the first LSU pitcher to throw back-to-back complete games since 2013, when Aaron Nola did it four times in a row.
Lange got all of the offense he needed in the 1st inning as the Tigers scored three times in that frame. Kramer Robertson started the rally with a walk. He scored on a single by Greg Deichmann.
LSU made it 2-0 when Beau Jordan walked with the bases loaded. A Josh Smith fly ball would score the third run of the inning.
An Antoine Duplantis RBI double in the 2nd inning capped the scoring. Duplantis continues to swing a hot bat as he was 2-for-4 with an RBI and a run scored.
LSU can clinch a series victory with a win over Auburn on Friday. Senior left-hander Jared Poche (8-3, 3.33) will make his final regular season start in Alex Box Stadium. Poche will receive his college degree before the game.
He'll be opposed by Auburn's Keegan Thompson, who is 5-3 with a 2.08 ERA.
Auburn has saved its top two pitchers for Games 2 and 3 of this series.
