Washington State (16-3, 5-2 Pac-10) won its third straight over the rival Huskies, after sweeping them last year, to rebound from an overtime loss at Stanford last week that knocked them out of the Top 25.

Washington (11-7, 1-6), playing without leading scorer Spencer Hawes, lost its third game in a row and has lost all six of its road games this season.

Washington came in averaging 83.4 points per game, 11th in the nation. Washington State leads the Pac-10 in defense, allowing 58 ppg. Washington's lowest output of the season had been 64 against Arizona State.

Hawes, averaging 15.2 points per game, injured his ankle in practice Friday and did not play. Forward Quincy Pondexter, also slowed by an ankle injury, led the Huskies with 16 points.

Washington made just 4 of its first 20 shots in the game, and was held scoreless for nearly 9 minutes during the Washington State run. Justin Dentmon's 3-pointer with 2:33 left in the half finally broke the Washington drought, making it 32-15.

A pair of 3-pointers by Ryan Appleby and a layup by Pondexter allowed Washington to close to within 34-23 at halftime.

But the Cougars opened the second half with a 21-4 run, behind a trio of 3-pointers and a regular basket by Low, for a 55-27 lead that killed any hopes of a Washington comeback. Low made 5 of 7 3-pointers in the game.
