Missouri State won 6-2.
The Bears came in to the three-game series winners of just three of their last eight games.
But the Bears got key contributions from freshmen in each win.
On Friday, Spencer Johnson had the go-ahead RBI. Freshmen Jon Harris and Andy Cheray picked up wins on Saturday and Sunday, respectively.
That marks 12-straight wins for MSU where a freshman has earned the victory on the mound, or knocked in the winning run.
The Bears travel to Saint Louis on Tuesday.
