BATON ROUGE, La. — LSU’s Rally Possum is no longer playing.

Michael Paez hit a walk-off RBI single in the bottom of the ninth inning late Sunday to give Coastal Carolina a 4-3 win over LSU in Game 2 of the Baton Rouge Super Regional at Alex Box Stadium.

Coastal Carolina swept the best-of-three series and advanced to the College World Series for the first time. LSU, which had 21 come-from-behind victories this season — including one against Arkansas in which a possum wandered onto the field, launching the “Rally Possum” craze in South Louisiana — finally ran out of magic.

The Tigers (45-21) left eight runners on base in the last three innings, and 12 in the game. Ten of those left on were in scoring position.

They overcame a 3-1 deficit in the seventh inning to tie it, but missed several chances to take the lead and left the door open for Coastal Carolina (49-16) to stage a rally of its own.

“Clutch hitting is a big, big part of the game. We’ve gotten so many clutch hits throughout the year at critical times and that’s why we were in the position we were in,” LSU coach Paul Mainieri said. “But, you know, hitting is the hardest thing to do in baseball, and any sport, really. Especially in those clutch situations, and we had the right guys up there many times and it just didn’t happen for us.”

LSU left the bases loaded in the eighth and ninth innings. It did tie the game in the top of the ninth when Jake Fraley beat out a bunt as Cole Freeman scored from second on an error on the play.

In the bottom of the ninth, Coastal Carolina got the winning run on base when Anthony Marks worked a leadoff walk and stole second. Paez then chopped a grounder over the head of third baseman Chris Reid and down the left field line, scoring Marks and sending the Chanticleers on to Omaha at last.

Coastal Carolina had not won a game in two previous super regional appearances,

“This is one of the few times in my life that I’m at a loss for words,” Coastal Carolina coach Gary Gilmore said. “I just felt like it was destiny for us.”

And for LSU, a disappointing ending to a magical season.

The Tigers won 17 of their last 20 games heading into the super regional and were the No. 8 national seed in the NCAA Tournament.

“I mean, obviously it’s unfortunate. It’s not what we planned but at the end of the day, we have to take it like men and understand what we didn’t do as well as we thought we were going to be able to do,” Fraley said. “And you know, it stinks. It stinks to put ourselves in that type of a situation and then it end the way that it did today.”
