The final weekend of Pac 10 play is underway, and all of Thursday's action has been completed.

UCLA has defeated Cal, 2-1, putting the Bruins atop the standings at 14-5.

Washington routed Stanford, 7-0, leaving each of these teams at 13-6.

Oregon has upset Arizona, 2-1 in 10 innings. The Wildcats' loss leaves them at 11-7 (U-of-A's final conference record will be short at least one game, as a rain-out at Cal last week won't be made up).
