BOULDER, Colo. — Zac Robinson broke Colorado's hearts again, leading No. 11 Oklahoma State past the Buffaloes, 30-17, tonight, four years after spurning a scholarship offer from the Buffaloes.

Playing in his home state for the first time since high school, Robinson threw for 217 yards and a touchdown and ran for another.

Coming off a 56-20 whipping at the hands of No. 2 Texas Tech last week, the Cowboys got off to another slow start, settling for chip-shot field goals on their first two drives, an early warning sign that this wouldn't be another offensive onslaught.

The Cowboys (9-2, 5-2 Big 12) have a week off before their showdown with archrival Oklahoma.
