BOULDER, Colo. (AP) Rashard Ross returned the second-half kickoff 100 yards for a touchdown to break open a close game and Taylor Kelly threw three scoring passes to tailback Marion Grice in Arizona State's 51-17 victory over Colorado on Thursday night.
Grice caught touchdown throws of 37, 16 and 20 yards from Kelly, who threw for 308 yards and five TDs with no interceptions thanks to a steady diet of successful screen passes. He also tucked it and ran for 67 yards through huge chunks of open space all night long.
The Sun Devils (5-1, 3-0 Pac-12) will take a three-game winning streak into their showdown next week against second-ranked Oregon.
The Buffaloes fell to 1-5 and 1-2 in conference play heading into the toughest portion of their schedule.
