Trey Porter drove in the go-ahead runs in the eighth inning, and Mississippi State took control of its bracket in the College World Series with a 5-4 victory over Indiana on Monday night.
The Bulldogs (50-18) need one win to reach next week's best-of-three finals. They're off until Friday, when they'll play Indiana (49-15) or Oregon State.
The Hoosiers will play Oregon State in an elimination game Wednesday at 8 p.m.
The Bulldogs erased a 3-2 deficit in the eighth. Brett Pirtle beat Will Nolden's throw home to tie it after DeMarcus Henderson smacked a one-out liner into right, and Porter sent Brian Korte's 3-1 pitch into the right-center gap to score Wea Rea and Henderson for a two-run lead.
Indiana got a run back in the ninth, but closer Jonathan Holder came on to get the last out in relief of Chad Girodo (9-1). Holder earned his 20th save.
Ryan Halstead (4-5) took the loss.
