Earlier results

First round, Wednesday

Game 1: Southern Cal 78, Arizona 65

Arizona’s nightmare season continued with its first loss in the opening round of the Pac-12 tournament since 2010. The Wildcats (17-15) were the tournament’s two-time defending champion; they have now lost 10 of their last 13 games.

Game 2: Colorado 56, California 51

Colorado will likely need to win the conference tournament if it wants a spot in the big dance, and it got off to a less-than-inspiring start with a win over lowly Cal (8-22, 3-15) to open its pursuit of the title. It was the ninth consecutive win in a tournament opener for Coach Tad Boyle.

Game 3: UCLA 79, Stanford 72

Sophomore Jaylen Hands led the way with 22 points and 11 rebounds as the Bruins advanced to the second round. Meanwhile, Stanford lost for the fifth time in six games to end its season.

Game 4: Oregon 84, Washington State 51

The Ducks entered the game with a four-game winning streak to end the regular season and continued rolling against former coach Ernie Kent and the Cougars. But will anything but a tournament title get Oregon into the Big Dance? Probably not: The committee likely does not look kindly on teams that lose to Texas Southern at home.
