Carrick Felix scored 20 points, Jordan Bachynski had 16 points and nine blocked shots, and Arizona State pulled away from cold-shooting Colorado down the stretch to beat the Buffaloes 65-56 on Sunday night.
Jonathan Gilling added 12 points and 10 rebounds for the Sun Devils (13-2, 2-0 Pac-12), who started their conference season 2-0 for the first time in five years.
Spencer Dinwiddie led the Buffaloes with 19 points. Askia Booker added 13.
Colorado (10-4, 0-2) led 20-7 early and 33-30 at the half but fell apart over an eight-minute second-half stretch three nights after they appeared to have beaten No. 3 Arizona on Sabatino Chen's 3-point bank shot at the buzzer, only to have officials wave off the basket after a video review. The call has been second-guessed across the country.
