Tournament Notes
Arizona's 31-point victory margin (90-59) over Oregon State in the 2nd round was the largest for any game in this tournament's history. It has since been broken, but still remains the second largest margin. This is the first and time only time in Pac-12 Tournament history that the 2 seed beat the 1 seed (as of 2013 these seeds have met 5 times). Like the previous two years, no universities met their arch-rival in this year's tournament. Three universities each had two players on the all-tournament team, which is the only time this has happened. There were no blocked shots in the game between Washington and Arizona, although this has happened in other tournaments. All tournament team
