Pac-12 commissioner Larry Scott speaks about bringing the Pac-12 basketball tournament to Las Vegas during a news conference, Tuesday, March 13, 2012, in Las Vegas. Las Vegas will begin hosting the tournament in 2013.

LAS VEGAS — The Pac-12 men's basketball tournament is moving to Sin City for the next three years.

Commissioner Larry Scott announced the deal on Tuesday at the MGM Grand hotel-casino in Las Vegas, standing poolside near a site known for boxing, not basketball.

Scott says the move, combined with moving the women's tournament to Seattle, will generate buzz and create atmosphere for the conference's fans.

The Pac-12 tournament running March 13-16 will be the fourth conference tournament in Las Vegas, along with the Mountain West, the Western Athletic Conference and the West Coast Conference.

Rossi Ralenkotter of the Las Vegas Convention and Visitors Authority says the tournament will establish Las Vegas as the town where March Madness begins.

The tournament will be the first time the MGM Grand's arena has hosted basketball.
