It's the fifth-straight year since joining the WCC in 2011-12 that BYU has advanced to the semifinals. The Cougars won the tournament titles in 2012 and 2015.
"I am really proud of these guys. We've had a fun year," BYU coach Jeff Judkins said. "Tonight wasn't the best that we've played, but as a team we've learned to play together and compete as a team. … I am really happy for them because we lost our last game, and it is tough to come back from a loss. Sometimes you get out of sync, but they really bounced back well.
