Derrick Williams had 26 points, 13 rebounds and one clutch block to help the Arizona Wildcats hold off the Men in Black from Washington, 87-86, during their “white-out” game at McKale Center today.

Williams blocked a shot from Washington’s Darnell Gant with just over two seconds left and the Wildcats hung on despite a shaky second half marred by turnovers.

The win, Arizona’s eighth straight, moved the Wildcats to 23-4 overall and 12-2 in the Pac-10 while Washington dropped to 18-8 and 10-5.

Solomon Hill scored under the basket after Jesse Perry was blocked with 25 seconds to go, giving UA an 87-86 lead. The Huskies then called timeout with 17.5 seconds left to set up a final play.

Matthew Bryan-Amaning was called for traveling with three seconds left but UA botched an inbounds pass when Hill threw the ball low and it bounced out of bounds off MoMo Jones’ foot.

Washington then had 2.2 seconds left and the ball to inbound from the baseline.  But Justin Holiday passed to Gant, whose shot was blocked out of bounds by Williams and a final inbounds attempt by the Huskies failed to result in a shot attempt.

While Williams led the Wildcats with 26 points and 13 rebounds while Bryan-Amaning had 24 points and 10 rebounds for the Huskies.

Only a handful of fans in the capacity crowd at 14,545-seat McKale Center were not wearing white and athletic director Greg Byrne said before the game that he jokingly asked a few of those who weren’t why they had not.

Not only did the fans wear white, but the UA band cheerleaders, and other spirit squad members worse while.

The Huskies, meanwhile, wore their black uniforms, adding even more contrast to the event.

The Wildcats took advantage of the extra energy in McKale Center early by scoring on their first seven possessions to take a 16-6 lead four minutes into the game when Kyle Fogg made a four-point play, being fouled by Overton on a three-point shot.

UA failed to score on three straight possessions but three-pointers by Jordin Mayes and Jamelle Horne put them ahead 25-15 with 11:47 left.

After eight minutes, the Wildcats already had five players hit three-pointers after Williams connected with 7:43 left to give UA a 30-22 lead.
