Big-12 wise, the only big shakeup came with Oklahoma State dropping from first to third, with Missouri and Nebraska both moving up.  The Tigers and the Huskers are white hot right now.  Missouri swept a home series vs. Baylor in convincing fashion, while Nebraska nearly swept a home series vs. Oklahoma.  Nebraska won the first two games.  The third game ended in a rare tie.  On Sunday all games must be completed by 5PM in order to students to get back to their campuses for Monday classes.  The final OU-NU game was called after ten innings with the two teams tied 9-9.
