PALO ALTO, California (Ticker) -- Dan Grunfeld made this a milestone day for coach Trent Johnson.
Grunfeld scored a career-high 29 points and helped Johnson pick up his first Pac-10 Conference victory as Stanford defeated No. 13 Arizona, 87-76.
Stanford (7-7, 1-3 Pac-10) pulled away on a 15-4 run midway through the first half, highlighted by a pair of 3-pointers from Chris Hernandez, and eventually led 39-36 at halftime.
Grunfeld, son of Washington Wizards executive Ernie Grunfeld, made three straight baskets during a 16-4 spurt in the second half, putting the Cardinal on top, 65-49.
He shot 10-of-12 from the field and 6-of-7 from the foul line for the game.
"We tried to dig in on defense, clean the boards and not give Arizona anything easy," Grunfeld said. "Everyone was in the flow of the game, moving the ball, looking for the open man."
Arizona (12-3, 2-1) crept to within 70-64 with 4:51 left, before Hernandez made a steal and fed Rob Little for a layup to extend the lead back to eight points.
The Wildcats had one last chance when they cut the margin to 76-71 with 85 seconds remaining. But Hernandez, who finished with 23 points, scored four straight to end the comeback attempt.
"I felt good, going into the game," Hernandez said. "Letting it fly felt good today. Last year's win (vs. Arizona) was very exciting. This was more serious. We needed this win. This was a confidence builder."
Little scored 16 points and grabbed 12 rebounds before fouling out, as Stanford won for the fifth time in its last six meetings with Arizona by shooting 58 percent (32-of-55) from outside.
"This team doesn't lack in character," Johnson said. "We're going to compete, try not to beat ourselves and make good decisions. These guys get in trouble when they try too hard. We can't try to be the group of guys who were here last year."
Channing Frye scored 20 points and grabbed 13 rebounds, while Hassan Adams added 19 and 10 for Arizona, which saw its nine-game winning streak snapped.
"Every time Stanford got a look, they knocked it down," Arizona coach Lute Olson said. "They did a good job, were patient and killed us with penetration."
Salim Stoudamire, who was 19-of-25, including 15-of-19 from 3-point range, in his last five games, scored 14 points on 4-of-9 shooting. He was 3-of-6 from the arc.
