Some sweeps last weekend produced big developments in the shape of the field, both in the hosting race and the at-large field. Louisville and UC Santa Barbara were two of the biggest movers as they swept key series that have vaulted them onto the host line and into the driver’s seat in their conference races. Florida State’s sweep of Clemson made its path to regionals much more manageable, and Houston’s sweep of Wichita State has the Cougars in a much better position than a week ago.
