The Pac-12 Conference holds an annual men’s basketball tournament with the winner getting an automatic bid to the NCAA Men’s Basketball Tournament.

The Pac-12 features 12 teams--Arizona, Arizona State, California, Colorado, Oregon, Oregon State, Stanford, UCLA, USC, Utah, Washington and Washington State.

The conference tournament begins March 11 and runs through March 14.

The Pac-12 was formed in 1916. It was known as the Pacific Coast Conference, Athletic Association of Western Universities, Pac-8 Conference and Pac-10 Conference before becoming the Pac-12.

The conference held men’s basketball tournaments from 1987 to 1990 and then 2002 to the present.

The conference tournament was initially halted due to poor revenue and lack of attendance among other issues.
