Clint Chelf threw three of Oklahoma State's five touchdown passes and the Cowboys shook off a disappointing Big 12 finish by dominating Purdue 58-14 in the Heart of Dallas Bowl on Tuesday.
    
The Cowboys, a year removed from a Fiesta Bowl win that capped the best season in school history, forced five turnovers and had another short touchdown drive after a 64-yard punt return from Josh Stewart.
    
It was the biggest bowl win for Oklahoma State since coach Mike Gundy was the quarterback in a 62-14 rout of Wyoming in the 1988 Holiday Bowl. The Cowboys (8-5) missed out on upper-tier bowls after narrow losses in their last two Big 12 games.
    
With former Purdue quarterbacks Drew Brees and Kyle Orton watching, Robert Mavre didn't get to 100 yards passing until Oklahoma State led 45-0 as the Boilermakers (6-7) fell to 0-4 on New Year's Day.
