Prior to the 2006 season, conference realignment again led TCU to change conferences as eight other C-USA members changed conference homes. The Horned Frogs joined the Mountain West Conference (MWC), where the Frogs competed for seven years (2006–2012). In each season in the MWC, TCU advanced to the NCAA Tournament and won at least a share of the Mountain West regular season title. In those seven years, TCU also won four MWC Tournament championships. During this era, TCU won its first-ever NCAA Regional Championship in 2009, and repeated the feat in 2010 and 2012. In 2009, the Horned Frogs advanced to its first NCAA Super Regional, where the Texas Longhorns eliminated TCU from the Tournament. In 2010, TCU and Texas met again in an NCAA Super Regional, but the Horned Frogs emerged from the rematch—advancing to the College World Series for the first time in school history. TCU compiled a 3–2 record in its first CWS appearance, eventually falling in the national semifinal to UCLA.
