It was over when...

Meanwhile, LSU reliever Caleb Gilbert (6-1) completely shut down the Bulldogs over 5 2/3 innings pitched. The sophomore right-hander retired 15 straight batters between the third and eighth innings to put Mississippi State's powerful offense to sleep. He allowed only two hits in relief of starter Jared Poche'.
