TUCSON, Arizona (Ticker) -- Stanford's muscle, grit and experience paved the way for another huge win at the McKale Center.
Josh Childress scored 18 points off the bench as the sixth-ranked Cardinal remained unbeaten and gained an early upper hand in the Pac-10 Conference race with an 82-72 victory over No. 3 Arizona.
Stanford (13-0, 4-0 Pac-10) won for the fourth straight year at Arizona, using stifling defense to build an early double-digit lead. The Cardinal became the first team to win four straight years at McKale Center since UCLA won here five seasons in a row from 1979-84.
"(There's) no secret," Stanford coach Mike Montgomery said. "This is just college basketball, there's no magic."
Seniors Matt Lottich and Justin Davis enjoyed their final visit to Tucson, leading the first Cardinal class to go unbeaten here. Lottich scored 17 points and Davis added 10 and 10 rebounds.
"I'm very blessed to be able to beat Arizona any time," Lottich said. "I've been surrounded by great teammates. I feel very fortunate."
Arizona (10-2, 2-1) had a nine-game winning streak snapped, shooting a paltry 19 percent (6-of-31) in the first half. The Wildcats trailed by double digits nearly the entire second half, pulling within 81-72 on freshman Mustafa Shakur's meaningless 3-pointer in the final seconds.
Stanford won by pounding the ball inside against Arizona's undersized frontcourt, allowing Childress, Davis and Rob Little to control the interior. The Cardinal established a 33-20 halftime edge as the Wildcats matched the lowest point total in a half under Lute Olson.
"Great defensive effort on our kids' part," Montgomery said. "In the first half, we didn't give up any easy shots. We obviously did a very good job of defending."
Arizona center Channing Frye managed just 12 points against the physical combo of Little and Davis. The Wildcats were forced to use freshman Ivan Radenovic to match the Cardinal's size and Radenovic was 2-of-10 for six points.
"They played with poise and intelligence," Olson said. "There's a reason they're undefeated. There's not going to be many teams able to beat them. We now have to run the table."
Heady point guard Chris Hernandez, who had 12 points and nine assists, held his own against Shakur and Arizona's pressure. The Cardinal did commit 20 turnovers, but were never threatened with a efficient all-around effort.
"We were able to control the tempo," Lottich said. "A lot of teams when they miss a shot, they chase the ball. We get back on defense and that slowed them down."
Arizona missed all 10 3-pointers in the first half and finished 4-of-21 from beyond the arc.
