Central Missouri State and Rockhurst University are both hoping to reach the Division II college world series. But they have to go through one another. CMSU is hosting the Central regional, which is underway today in Warrensburg. The Mules are the top seed, after winning the MIAA title. Rockhurst, led by outstanding pitchers Jonathan Krysa and Jason Forge, are the defending champs of the regional. Rockhurst opens the tournament this afternoon against Winona State. CMSU plays tonight against Minnesota State-Mankato.
