Colorado (3-0) led the final 10 minutes of the game, holding off Baylor (3-1) despite horrendous free-throw shooting. The Buffaloes limited Baylor scoring threat Pierre Jackson -- who scored 31 points Thursday -- to 12 points, and held the Bears to 36.7 percent shooting overall.
Baylor led midway through the second half but the Colorado defense proved too tough, and the Bears had just five field goals the rest of the way. Colorado scratched out just enough points to keep ahead with back-to-back baskets from Dinwiddie with a 57-52 lead with 4:07 to go.
Dinwiddie had the team's final field goal of the day, which was needed as the Buffaloes were just 1-of-6 from the free-throw line down the stretch and 4-of-18 for the game.
Colorado's Askia Booker led all scorers with 19 points but scored just three in the second half. Dinwiddie finished with 11 points and Andre Roberson had 13 rebounds.
Baylor got 17 points from Cory Jefferson in addition to the 12 from Jackson.
