The 2011 Pac-10 Championship tournament is underway in downtown Los Angeles at the STAPLES Center.
The play-in games kicked off the event on Wednesday night with Oregon State "upsetting" Stanford and Oregon taking care of Arizona State.
The bracket gets going on Thursday with the quarterfinal matchups and in a league with such parity (read: mediocrity), anyone can beat anyone else on a given night. Add in the fact that the Pac-10 tourney is played on a neutral floor and upsets are primed to happen.
Here are the potential upsets for this weekend at STAPLES, ranked from lowest to highest in probability.
