Arizona (21-4, 10-1 Pacific-10) has won 30 consecutive games over Washington State, the longest winning streak in the nation among conference rivals. The Cougars have not defeated Arizona since 1986.

Washington State (5-15, 0-11) has not won since beating Portland State on Dec. 20. This was their worst home loss since Feb. 1, 1990, when Arizona beat them 86-62.

The Cougars had little chance of breaking the losing streak Saturday, as Arizona opened the game with a 3-point basket by Luke Walton and never trailed.

The undersized Cougars, respectful of 7-foot-1 Arizona center Loren Woods, hesitated to take the ball inside. But they also failed to connect from outside, and Woods still ended up with five blocks. Washington State has no players taller than 6-foot-8 Chris Crosby.

Michael Wright scored 19 points and grabbed eight rebounds for Arizona.

Crosby led Washington State with 14 points. David Adams had 10 for the Cougars, who shot just 34 percent in the game, compared to 60 percent for the Wildcats.

Arenas scored 11 points in the first half, including consecutive baskets that lifted Arizona to a 22-11 lead with 9:15 left. A 15-3 Arizona run over the final seven minutes have them a 39-19 halftime lead.

Washington State made just eight-of-33 field goals in the first half for 24 percent, while the Wildcats were shooting 58 percent.

Washington State did not shoot a free throw in the first half, and Tyrone Evans sank their first one with 10:56 left in the game.

The second half started a little more evenly, but Wright's basket and two free throws lifted Arizona to a 54-31 lead with about 12 minutes left.

Seven straight points by Arenas gave Arizona a 61-32 lead.

The Cougars have lost 15 straight Pac-10 games over two seasons and the 0-11 league mark this season is the second-worst opening in their history.
