PITTSBURGH — Mason Rudolph’s message to the rest of the Oklahoma State offense was simple. Playing half a country away from home against a Pittsburgh team that took the Cowboys to the wire a year ago, Rudolph didn’t want to leave anything to chance in the rematch.

“We wanted to come out and blow the top off this thing,” Rudolph said.

Done. And then some.

Rudolph gave his Heisman Trophy campaign an eye-popping kick start by throwing five touchdown passes during an immaculate first half to help No. 9 Oklahoma State rout the Panthers 59-21 on Saturday.

The Cowboys (3-0) reached the end zone on each of their first seven possessions, piling up 516 yards in the process, a school record for most yards in one half.
