STILLWATER, Okla. -- No. 3 Oklahoma State opened its 2012-13 season with a 35-10 rout against Pennsylvania, highlighted by pins at the 157, 197 and 285 weight classes.

Seven Cowboys entered the match ranked nationally and each picked up a win and bonus points.

“It was a good win for us,” Oklahoma State coach John Smith said. “Bottom line, if you go out, give the effort and don't just sit around and do nothing, then you're in every match.”

The Cowboys had a rough start, losing three of the first four matches. At 133 pounds, Jon Morrison picked up the first points for OSU with an 11-3 decision versus Penn's Geoffrey Bostany.

Providing the momentum needed for the Cowboys was 157-pounder Alex Dieringer, who, in his first starting performance for OSU, pinned Mark Pinero in just 49 seconds. He was followed by Tyler Caldwell’s 15-4 win against Casey Kent and top-ranked 174-pounder Chris Perry’s 21-6 technical fall versus Ian Korb. Chris Chionuma also had his first start for the Cowboys and claimed an 18-3 technical fall against Canaan Bethea in 5:06.

The final two matches resulted in pins when Blake Rosholt finished his opponent in 4:23 and Alan Gelogaev rolled Kyle Cowan in 5:18.
