Editing Western Athletic Conference (section)

===Success and first expansion===
The conference proved to be an almost perfect fit for the six schools from both a competitive and financial standpoint. Arizona and Arizona State, in particular, experienced success in baseball with [[Arizona Wildcats baseball|Arizona]] garnering the 1963 [[College World Series]] (CWS) runner-up trophy and [[Arizona State Sun Devils baseball|ASU]] winning the CWS in 1965, 1967, and 1969. [[Colorado State University|Colorado State]] and [[Texas–El Paso]] (UTEP), at that time just renamed from Texas Western College, were accepted in September 1967 (joined in July 1968) to bring membership up {{nowrap|to eight.<ref name=desaddtw>{{cite news |url=https://news.google.com/newspapers?id=nKsvAAAAIBAJ&pg=7080%2C1580995 |work=Deseret News |location=(Salt Lake City, Utah) |title=WAC does it!

With massive growth in the state of Arizona, the balance of WAC play in the 1970s became increasingly skewed in favor of the Arizona schools, who won or tied for all but two WAC football titles from 1969 onward. In the summer of 1978, the two schools left the WAC for the Pac-8, which became the Pac-10, and were replaced in the WAC by [[San Diego State Aztecs|San Diego State]] and, one year later, [[University of Hawaiʻi at Mānoa|Hawaii]]. The WAC further expanded by adding [[Air Force Falcons|Air Force]] in the summer of 1980. A college football national championship won by [[1984 BYU Cougars football team|Brigham Young in 1984]] added to the WAC's reputation. This nine-team line-up of the WAC defined the conference for nearly 15 years.
