Derrick Williams had 21 points and eight rebounds as Arizona topped Stanford 78-69 on Thursday night to grab first place in the Pac-10.

It was the fourth straight win for the Wildcats and the seventh in their last eight games.

"Our team played with a lot of poise and executed well on the road," Arizona coach Sean Miller said. "The shots we took and got were good shots. We had a problem rebounding, but we put together a couple of good shots and got a key rebound or two, and kind of broke the game open in the last 4 minutes."

The win allowed Arizona to slide ahead of Washington, who lost to Oregon State, in the conference standings.
