STILLWATER, Okla. -- No. 3 Oklahoma State finished the dual portion of its season in dominating fashion on Friday as the Cowboys (17-1) dropped No. 10 Missouri (14-5) 32-9 to claim their sixth win against a top-10 opponent this year and finish with a flawless 6-0 record against Big 12 opponents.

With that perfect conference record, the Cowboys were presented the inaugural Big 12 regular-season wrestling championship at the conclusion of the dual. Oklahoma State now has 11 Big 12 team titles, eight seasons without a loss to a Big 12 opponents and 45 total team conference championships.

Oklahoma State started the dual strong and never looked back, holding a 17-0 lead after the first three bouts with a fall at 141 pounds from Josh Kindig against Brandon Wiest, a technical fall at 133 pounds from Jordan Oliver against Eric Wilson and a Missouri forfeit at 125 pounds.

"Well, it was a little different because, obviously, their [125-pounder] was out," coach John Smith said. "Overall, it was a good effort from the standpoint of being a little bit more aggressive and putting points on the board at key times."

A pair of seniors, wrestling in their last career matches inside Gallagher-Iba Arena, came through with some of the biggest wins of the dual, including Jamal Parks' 10-3 decision against No. 13 Kyle Bradley at 149 pounds and Cayle Byers' 7-1 decision against No. 5 Brent Haynes.

"I was pleased with the outcome," Byers said. "I didn't go in there to wrestle any different than I have in the past. I just trained hard and stuck to the game plan the coaches had and it turned out well."

Parks' win wrapped up a perfect regular season for him at 28-0. He joins fellow Cowboy Chris Perry with an undefeated regular season, as Perry won 6-3 at 174 pounds against No. 15 Dorian Henderson to push his season mark to 24-0.

"It feels great," Parks said. "This is a great year to have my first undefeated season. I've never had one, so I'm looking forward to grinding and keep doing what I'm doing."

Other OSU wins included Dallas Bailey's 4-1 decision against Zach Toal at 165 pounds and Austin Marsden's 3-2 victory against No. 20 Devin Mellon, giving OSU wins in eight of the 10 bouts.

"This was the first time we've had a regular conference championship in dual meets, and it wasn't easy," Smith said. "It's nice, but the whole thing changes if Chris Perry doesn't get a technical fall [at OU]. We like to collect hardware. That's our focus."
