DES MOINES, Iowa -- Znick Ferrell pulled off a big upset in his season debut and Central Oklahoma won a trio of one-point matches to get past Upper Iowa in the quarterfinals of the NWCA Division II National Duals Saturday afternoon.

The No. 3-ranked Bronchos and No. 10 Peacocks tied 18-18, but UCO advanced to Sunday's semifinals on criteria decision by winning six of the 10 individual matches.

It was the 14th consecutive victory for the Bronchos (4-0), which will take on No. 4 Newberry in Sunday's semifinals. Top-ranked Notre Dame (Ohio) and fifth-rated St. Cloud State collide in the other semifinal, with the two winners meeting for the title and the two losers for third place.

Ferrell knocked off No. 4 Blake Sorensen 11-5 at 184 pounds and UCO got one-point wins from 157 Cory Dauphin, 165 Chris Watson and 174 Colton Gallo. Josh Breece opened the dual with a 7-1 victory at 125 and 133 Casy Rowell had a 2-0 shutout.

The Bronchos were pinned at 141 and 197 in addition to suffering upset losses at 149 and heavyweight, with a 3-2 setback in the final match allowing UIU to tie the dual and arrange the criteria decision.

"We had some guys really suck it up and win tight matches, but I was disappointed with what we did at several weights," head coach David James said. "We were fortunate to win the dual and we're going to have to wrestle a lot better tomorrow if we want to continue moving forward."

Breece picked up his first college win at 125 as the freshman was in control all the way for the 7-1 triumph that gave UCO an early lead. Rowell used a second-period escape and third-period ride-out to secure his 2-0 shutout and make it 6-0.

The Peacocks tied it at 141 when Jordan Roths pinned Dustin Reed with just 18 seconds remaining and the match tied 7-7 before going ahead 12-9 on Edwin Cooper's 9-4 win against the top-ranked Basks at 149.

It was the first loss of the season after a 20-0 start for Basks, who overcame an early 4-0 deficit to the fifth-ranked Cooper to tie it 4-4 in the third period before Cooper won it with a late takedown and near-fall.

Cory Dauphin trailed 4-1 in the second period against Zak Benitz, but tied it on a near-fall with 45 seconds left and won his 30th consecutive match with a riding time point.

Watson followed with his 2-1 win in staying unbeaten (16-0), using a second-period escape and riding time point to edge Dalton Westerlund.

Gallo came through with a gutsy 7-6 victory that upped UCO's lead to 15-9, getting two reverses and a takedown to build a 6-2 lead before holding on down the stretch.

Ferrell then came through with the biggest win of the dual in upending Sorensen in his first appearance of the season and at new weight.

A national qualifier at 197 last year who had been out all season with injury, Ferrell scored an opening-minute takedown and had a 3-2 lead with 30 seconds left. He made that 5-2 with another takedown on the edge when Sorensen suffered a knee injury and added three takedowns in the final 20 seconds for the 11-5 triumph.

That made it 18-9, but the Peacocks got the fall at 197 to get close and then Logan Hopp upset third-ranked Cody Dauphin 3-2 at heavyweight to arrange the tie that became a win.
