Robert Dozier had 18 points, Chris Douglas-Roberts scored 17 and second-ranked Memphis beat No. 17 Arizona 76-63 on tonight, the third time the Tigers have knocked off a ranked opponent this season.

"It wasn't easy," Douglas-Roberts said. "None of these games have been. We've been playing the best teams in the nation. Any one of them we could see in the Final Four. To be able to beat them, we feel like we can beat anyone."

Chase Budinger had 20 points, and Jordan Hill battled foul trouble to score 14 for the Wildcats (9-3), whose six-game winning streak ended.

"It hurts," Arizona guard Jawann McClellan said. "We had a chance, we just let it get away."

Shawn Taggart added 15 points and seven rebounds to help the Tigers (11-0) match the second-best start in school history, dating to the 1982-83 season.

Despite one of the nation's toughest schedules, Memphis still doesn't have a blemish.

"I love it," Taggart said. "Look at who we've beat. We still have some really tough games ahead. But to be where we are right now, it's hard not to be happy."

Calipari scheduled tougher opponents this season to help offset the Conference USA schedule his Tigers begin playing in January.

Memphis has rolled through the thick of its daunting nonconference schedule this season much like it has through C-USA in years past: untouched.

The Tigers already have defeated Georgetown, Southern California, Oklahoma, Connecticut and Cincinnati.

The strong schedule should not only make the Tigers better come March, it may bolster their bid for a No. 1 seed in the NCAA tournament.

They still host Gonzaga on Jan. 26, and in-state rival Tennessee on Feb. 23. The Tigers went 16-0 against C-USA opponents last season.

"To play teams like this early in the year will help us make that push in the tournament," Calipari said. "To beat teams like this just adds confidence. We're not going to see anything in the tournament we haven't seen already."

The Wildcats suffered a huge blow before the game even began.
