BOULDER, Colo. (AP) - McKinley Wright IV scored 21 points, D'Shawn Schwartz added 20 and 24th-ranked Colorado overcame a cold start, a coach who lost his cool and a 16-point second-half deficit to beat short-handed Stanford 81-74 Saturday.
All of Tyler Bey's 11 points and nine of his dozen boards came in the second half when the Buffaloes shot 70% from the floor, 100% from behind the arc and 85% from the stripe.
That followed an awful first half in which the Buffs shot 28% from the floor, 23% from three-point range and 54% from the line.
At 19-5 overall and atop the Pac-12 at 8-3, the Buffaloes are off to the best start in their history, topping the 1954-55 and 1968-69 squads that started out 18-6.
Stanford (16-7, 5-5), which led 39-23 early in the second half, lost its leading scorer, Oscar Da Silva, to a head laceration on a scary collision early in the second half, and he finished with 3 points, 13 below his average.
Jaiden Delaire scored 19, Tyrell Terry had 18, Spencer Jones 14 and Isaac White 12 for the Cardinal.
The Buffs trailed 33-22 at halftime following a five-point swing in the final two-tents of a second of the first half.
Terry fired up a 3-pointer that Eli Parquet got a hand on. Colorado coach Tad Boyle was assessed a technical after Parquet was called for the foul.
Terry sank all five free throws, sending Stanford into the locker room with an 11-point lead instead of 6.
Da Silva left the game with 16:28 remaining after slamming his head on the floor while defending a breakaway by Evan Battey, who had stolen the ball and was charging toward the basket when they collided.
A body board was brought out but eventually Da Silva sat up on his own and was helped off to the locker room. He didn't return. Battey also was escorted to his locker room but later returned and finished with 13 points.
Before play resumed after the scary scene, both teams huddled at midcourt in a team embrace. Schwartz sank both free throws for Battey to cut Colorado's deficit to 41-32.
Battey returned minutes later with the Buffs down 47-41, and his runner gave Colorado a 51-49 lead. The Buffs took the lead for good on Bey's two free throws with 7:44 remaining that made it 58-56.
Stanford: The Cardinal was hoping to follow an 80-70 win over Oregon with another victory over a ranked team but Stanford sorely missed Da Silva and starting guard Bryce Willis, who sprained his right ankle in a loss at Utah on Thursday night and didn't play. Willis scored a dozen points in the Cardinal's win over Colorado last season.
Colorado: The strong storm-back will keep the Buffs from falling out of the poll and could serve as a springboard to a strong finish in the Pac-12. The Buffs hit all eight of their 3-pointers in the second half after going 3-for-13 in the first half. And they sank 23 of 27 free throws after going just 7-for-13 from the stripe before halftime.
Stanford returns home to host Arizona State on Thursday night.
Colorado visits Oregon on Friday night.
