Pac-12 Softball: Final Regular-Season Rankings

That's it. It's over. The regular-season is done.

In the final USA Today/NFCA Division I Top 25 Poll of the 2012-13 season, Oregon was voted as the top Pac-12 team at No. 3, behind unanimous No. 1 Oklahoma and No. 2 Florida. The Sooners are champions of the Big 12 conference, the Gators of the SEC conference and as mentioned before, the Ducks of the Pac-12. Oregon's No. 3 ranking is its highest of the season, of which it earned for its second week in a row. Arizona State finished behind in fourth, up from last week's No. 5 ranking.

Who's ready for some postseason play?
