BATON ROUGE The LSU Tiger baseball team lost 4-3 to Coastal Carolina in a must-win situation against Coastal Carolina on Sunday night in the NCAA's Baton Rouge Super Regional at Alex Box Stadium, ending the Tigers' season.

LSU (45-21) started junior left-handed pitcher Jared Poche on the mound on four days rest, the third time he's done that this season.

Poche was an immediate victim of bad luck as the lead-off hitter for the Chanticleers, Anthony Marks, reached on what would've been a routine out to first base. Marks then moved to second on a deep fly out to centerfield, to third on a wild pitch and then scored on a wild pitch strike-out as the ball got away from catcher Michael Papierski.

Coastal followed that up with an RBI single from GK Young that scored Connor Owings to make it 2-0 after one inning of play. The Chanticleers would tack on one more run.

Coastal was leading 3-2 in the top of the 9th when Cole Freeman reached on an error by the second baseman and advanced to second on a wild pitch. Antonie Duplantis followed with a walk before Jake Fraley reached on a bunt that allowed Freeman to score. Following an intentional walk to Greg Diechmann, the Chanticleers got out of it by striking out Brody Wofford and getting Beau Jordan to line out to left to make the score 3-3 heading into the bottom of the ninth.

In the bottom half of the inning, the Tigers never got an out. Anthony Marks walked to begin the inning, then stole second. Michael Paez followed that up with a chopper that made it through the infield allowing Marks to score the winning run.

The Tigers' backs were against the wall after Coastal (49-16) won game one of the best of three series 11-8 on Saturday night.

The win earns Coastal Carolina a trip to Omaha, Nebraska for the College World Series, joining Texas Tech, Miami, Oklahoma State, UC-Santa Barbara, TCU and Arizona as teams who have clinched a spot.

The Florida-Florida State series is the only one that remains undecided. The Gators and Seminoles will play again Monday.
