BATON ROUGE, La. (AP) -- LSU scored five runs in the ninth inning, including Sean Ochinko's go-ahead single, as the Tigers rallied to stave off elimination in their super regional series with a 9-7 win over UC Irvine on Sunday.

The deciding third game at LSU's Alex Box Stadium is Monday night.

Trailing 7-4, LSU (47-17-1) loaded the bases with no outs when Jared Mitchell, who homered in the eighth, walked to force in a run. Pinch-hitter Nicholas Pontiff drove in a run on a fielder's choice, Blake Dean hit an RBI single to tie it and Ochinko followed with a chopper over the third baseman's head to drive in the go-ahead run. DJ LeMahieu's sacrifice fly capped the rally.

Louis Coleman (7-0) allowed one hit in the final three innings for LSU, which had its 23-game winning streak ended the night before. The Tigers struggled against UC Irvine starter Daniel Bibona, who scattered nine hits over 7 1/3 innings, but got to work against the Anteaters' bullpen.

Closer Eric Pettis (4-3) entered in the eighth and allowed five runs on five hits in one inning to take the loss for UC Irvine (42-17).
