Oklahoma State is the only team to depart from the rankings. The Cowboys dropped their second-straight home series to Baylor and are gone as a result. Florida International, which rode a 15-game winning streak to Sunday and is in the mix for the Sun Belt regular season title, entered the rankings for the first time this season at No. 24.
The conference breakdowns are as follows: ACC 6, SEC 4, Big 12 3, Conference USA 2, Pac-10 2, Sun Belt 2 and Big East, Mid-American, MWC, Big West, Atlantic Sun and WAC all with one representative.
The Perfect Game Top 25 is released each Monday during the season, and always will include an additional listing of 25 teams to watch and a live chat with college baseball managing editor Kendall Rogers.
