Williams leads Arizona to 78-69 win over Stanford

STANFORD, Calif. (AP) -- Derrick Williams shrugged off pain in his right pinky to score 21 points and grab eight rebounds, and No. 21 Arizona beat Stanford 78-69 on Thursday night for its fourth straight victory.

The sophomore star had part of his shooting hand buried in tape and gauze to protect his pinky after it was bent backward against UCLA last week and still put together a complete performance. Lamont Jones added 15 points, and Jesse Perry scored 12 to help the Wildcats (19-4, 8-3) overtake Washington for the Pac-10 lead after the Huskies lost to Oregon State earlier in the night.

Jeremy Green had 21 points, and Josh Owens finished with 13 points and nine rebounds for a Stanford (11-10, 4-6) team that suddenly is struggling at home. After winning their first eight at Maples Pavilion this season, the Cardinal are 1-3 since.
