LAS VEGAS (AP) — CJ Ellerby scored 30 points and hit six 3-pointers, helping Washington State knock off Colorado 82-68 in the final Pac-12 tournament game with fans.

The Pac-12 followed suit of the NCAA and other major conferences by limiting the final three days of its tournament to essential personnel only. 

With a few thousand fans in the stands, the 11th-seeded Cougars jumped on Colorado and didn't let up, quickly turning the final game of the opening round into a rout. 

Isaac Bonton added 15 points, despite shooting 5-17 from the floor.  He also had 6 assists and 4 rebounds.

It's WSU's first Pac-12 tournament win since 2009.  It's also the first time an 11 seed won a tournament game.

McKinley Wright IV had 21 points and Tyler Bey 19 to lead the Buffaloes. 

The Cougars will face the #3 seed Arizona State on Thursday in the quarterfinals.
