The 2012-13 regular-season is over, which means it's time to focus on the postseason. Selection Sunday took place on May 12 and eight Pac-12 teams were selected to play for the title in a group of 64. The conference has the second-most teams only behind the SEC, which advances 11, including last year's winner Alabama.
Arizona, Arizona State, California, Oregon, Oregon State, Stanford, UCLA and Washington will all play in the NCAA Regionals taking place this weekend.
31 teams earned automatic qualification while the other 33 spots were filled with at-large selections. The top-16 teams were seeded nationally and will compete at one of the regional sites this weekend. Four teams will play at each of the 16 regional campuses in a double-elimination tournament.
It was no surprise that Big 12 champions Oklahoma (47-4) was selected as the No. 1 overall seed in the tournament. The Sooners will play automatic qualifiers Marist from the Metro Atlantic Athletic Conference (MAAC).
