The NCAA softball tournament field is set with 64 teams all fighting to reach the Women's College World Series. The big question is whether any team can knock off Oklahoma. The Sooners, who start as the No. 2 seed, will be going for a record fourth consecutive title. But there are a host of teams hoping to knock them off, including Texas, Tennessee and Florida.

The road to the WCWS in Oklahoma City starts spread across 16 regional locations. One team from each site advances to super regionals, where eight head-to-head matchups in best-of-three series will determine the field that plays for the national title.
