TAHLEQUAH, Okla. – Northeastern State held Missouri Southern to just one hit and closed out the regular season with a 4-0 win Saturday at Rousey Field.

The RiverHawks clinched a postseason berth just as the first pitch was thrown in Tahlequah, thanks to Missouri Western's 5-0 loss to Central Oklahoma in Edmond. NSU will be the No. 10 seed and is set to face the No. 7 seed at 1 p.m. Wednesday in Joplin, Missouri.

Neither team scored until the fifth inning, when a leadoff single and an error opened the door for NSU to plate two runs. Colton Ayres and Mason Ruiz each delivered RBI singles to the outfield.

Xavier Sanchez added to the lead in the sixth with a two-out single that slipped into right field. In the seventh, Missouri Southern committed its fourth error of the afternoon, allowing another run to score when a throw from third sailed into foul territory.

Missouri Southern (26-24, 18-18 MIAA) managed just a leadoff double—their only hit of the game—and was held scoreless for the final 17 innings of its season.

Diego Murillo led the RiverHawks at the plate with three hits, while Sanchez added two. NSU finishes the regular season with a 16-34 overall record, including 13-23 in MIAA play.

Six pitchers took the mound for NSU, with Sullivan Lane earning the win after tossing two scoreless innings and striking out three.

Wednesday's game, along with any additional NSU postseason contests in Joplin, will be broadcast live on Lakes Country 102.1 FM in Tahlequah.
