Baton Rouge, La. -- LSU overcame a shaky defensive start to the NCAA Baseball Regional to score 10-unanswered runs and defeat No. 4-seed Texas Southern, 15-7, on Friday afternoon at Alex Box Stadium, Skip Bertman Field.
LSU (44-17) overcame five fielding errors that led to six unearned runs in the first five innings. After trailing Texas Southern (20-33), 7-5, following the top of the fifth inning, LSU scored four runs in the fifth, four in the seventh and two in the eighth.
The homestanding Tigers scored 15 runs, the most in an NCAA postseason game in the new Alex Box Stadium. LSU last scored more than 15 in NCAA postseason play against UC Irvine in 2008, the final game at the old stadium.
With 16 strikeouts, LSU's four pitchers matched the program's postseason record set by Brett Laxton in the 1993 College World Series championship game against Wichita State.
With LSU trailing 6-5 in the top of the fifth inning, right-hand pitcher Caleb Gilbert (5-1) entered in relief of starter Jared Poche'. Gilbert tossed 2 2/3 shutout innings while allowing only two hits with six strikeouts to shut down Texas Southern.
LSU center fielder Zach Watson, a freshman from Ruston, was 2-for-4 with two runs and four RBI. He became the first LSU player to hit two home runs in an NCAA postseason game since Ryan Schimpf in the 2008 Super Regional against UC Irvine - the final game at the old Alex Box Stadium.
LSU catcher Michael Papierski went 2-for-2 and also scored twice with four RBI, while Cole Freeman went 2-for-3 with two walks and three runs scored.
LSU advanced to the winners' bracket of the four-team, double-elimination NCAA Regional. The Tigers will face No. 2-seed Southeastern Louisiana.
