IOWA CITY, Iowa Oregon State 157-pounder Eric Jorgensen and 174-pounder Nathan Coy were headed for the quarterfinals when the first day of the NCAA Wrestling Championships concluded Thursday night at Iowa State University.

The Beavers are in 13th place in the team race and have six of their seven entrants still in the tournament going into todays action.

I thought it could have been better, but any time you get a win at this level, in this competition, its great, OSU head coach Joe Wells said.

So six guys of the seven we brought are still wrestling, and now what we need to do is keep them wrestling all day Friday and have them wrestling on Saturday.

In this mornings quarterfinals, the fourth-seeded Jorgensen met 12th-seeded Shane Roller of Oklahoma State. The eighth-seeded Coy met top-seeded Josh Koscheck of Edinboro.

Jorgensen, a senior from La Grande, reached the quarterfinals with a 13-1 major decision over Max Odom of Harvard and a 7-1 win over Shaun Shapert of Edinboro.

Jorgensen defeated his quarterfinal opponent, Roller, 10-9 in overtime in a Feb. 2 dual meet at Oklahoma State.

Eric had two good matches, against two tough kids, and he wrestled well, Wells said. He dominated, he set the tone and he dictated what happened out there. Now hes got a big match Friday morning.

Beavers in the second round of wrestlebacks are 125-pounder Nathan Navarro, 133-pounder Ben Richards, 141-pounder Shane Cunanan and 11th-seeded heavyweight Jason Cooley.

The only OSU wrestler eliminated on the first day was 165-pounder Jed Pennell, and he recorded team bonus points for a pin before bowing out.

Coy, a junior, beat Cassidy Shults of Bloomsburg 8-4 and ninth-seeded Perry Parks of Iowa State 10-9. Coy wrestled Koscheck in the Las Vegas Classic on Dec. 2 and was pinned in 2:30.
