The jewel of this weekend's set of college softball tournaments is the Kajikawa Classic hosted by Arizona State. In addition to the Sun Devils, the field includes top-ranked Arizona, Texas A&M, and Northwestern (the latter two teams are also ranked within the top 7 nationally). ASU and U of A will not play each other in this tournament.
Elsewhere, the University of Texas hosts the Time/Warner Cable Invitational. The Longhorns are right around the border of the national top 25 (in it, according to one poll, and out of it, according to the other). Two other participants, Michigan and Cal State Fullerton, are in the top 25, with Penn State rounding out the field.
