BATON ROUGE, La. (AP) - Tristan Gray homered twice and drove in five runs to help Rice prolong its postseason with a 13-6 victory over Texas Southern on Saturday in the NCAA tournament's Baton Rouge regional.

Glenn Otto (7-4), who entered a tie game to start the sixth, pitched three scoreless innings for the victory. Andrew Dunlap and Ryan Chandler also homered for Rice (32-30), which pounded out 17 hits.

Robert Loza (2-2), who allowed three runs in the seventh, took the loss for Texas Southern (20-34), which was eliminated. Christian Sanchez had three hits and knocked in three runs for TSU.

Both starters - Rice's Zach Esquivel and TSU's Seth Oliver - were driven from the game in the second inning, after which the game was tied 5-5.

The game began 47 minutes late because of rain, which also caused a one-hour, 22-minute delay in the fifth.
