Western Athletic Conference
The WAC is the sixth oldest among the nation’s 11 Division I-A conferences. Its history traces back to July 27, 1962, when the original six-team league of Arizona, Arizona State University, Brigham Young University, New Mexico, Utah and Wyoming began competition. Arizona State claimed the league’s first NCAA title when the Sun Devils won the College World Series trophy. New Mexico State University is the longest tenured current member, having joined in 2005 (although the school is leaving after the 2022-2023 school year).
During 2010, the WAC had many announcements of membership changes. Boise State University, which does not field a baseball team will be joining the Mountain West Conference in 2011-2012. University of Nevada and Fresno State University join the MWC in 2012-2013. University of Texas at San Antonio, University of Texas at Arlington and Texas State University–San Marcos, along with non baseball schools Seattle University and University of Denver will be joining the conference in 2012-2013. University of Hawai'i at Manoa will be joining the Big West Conference (except the football program which will play in the MWC) in the 2012-2013 school year. Dallas Baptist University and California State University, Bakersfield have accepted affiliate membership in the WAC in baseball only beginning in 2013 . Finally, UT San Antonio and Texas State will be leaving after one year to join Conference USA and the Sun Belt Conference, respectively in 2013-2014.
