MINNEAPOLIS -- No. 2 Iowa advanced through the quarterfinals of the 2013 NWCA/Cliff Keen National Duals with a 21-16 victory against No. 9 Cornell on Friday at the University of Minnesota's Williams Arena.

The teams split 10 matches, but the Hawkeyes opened the dual winning a top-five matchup, and scored bonus points in each of its other four wins.

"We split 10 matches, 5-5, so it was tight," Iowa head coach Tom Brands said. "We advanced as a team, which is good, but we've got a lot to talk about with each individual guy. We'll look forward and get ready for Minnesota."

Top-ranked 125-pounder Matt McDonough got the Hawkeyes started, though not immediately. He gave up a takedown two seconds into the match before escaping and adding a takedown to take a 3-2 lead into the second period. He scored a reversal and takedown in the second frame, and put together a two-minute ride in the third period to defeat No. 5 Nahshon Garrett 8-3.

Tony Ramos extended the Iowa lead to 9-0 with a fall in 6:11 at 133 pounds against Bricker Dixon. Ramos scored five takedowns in the first, three in the second and was working on nearfall points when finished the pin in the third.

"I went out, wrestled hard, and knew I had worn him down," Ramos said. "Coach said go for the pin, so I worked on top, worked the legs and got the fall."

Cornell cut the lead to 9-6 with consecutive 3-1 wins at 141 and 149 pounds. Mark Ballweg (141) and Michael Kelly (149) both gave up third-period takedowns to No. 10 Mike Nevinger and Chris Villalonga in their respective losses.

Derek St. John extended the Iowa lead to 13-6 with a major decision as the nation's top-ranked 157-pounder scored a takedown with 20 seconds left to secure bonus points and put the final touches on a 12-3 win against Jesse Shanaman.

Cornell answered at 165 pounds when top-ranked Kyle Dake defeated Nick Moore,13-4, pulling the Big Red back within three points at 13-10.

Mike Evans then pushed the Hawkeyes' lead back to seven with an 11-2 win versus Duke Pickett at 174 pounds. Evans scored a takedown in the first period, extended his riding time to 3:48 with a ride-out in the second, and worked in three more takedowns in the final period to earn his seventh major decision of the season.

Trailing 17-10, Cornell forced a decisive heavyweight bout with wins at 184 and 197 pounds. Ethen Lofthouse dropped a one-point decision to fourth-ranked Steve Bosak at 184, and Nathan Burak fell 6-3 to Jace Bennett at 197.

Iowa (20-1) needed a win at 285 to advance to Saturday's semifinals, and sixth-ranked Bobby Telford delivered with a 9-0 shutout against Jacob Aiken-Phillips. Telford opened the first period with a takedown, scored a reversal to begin the second, and added another takedown in the third en route to the major decision.

"It was just another match," Telford said when asked if he was ready for the dual to be decided at heavyweight. "Like I said last time, you have 10 matches, you get what you get done, and you should have good results."

Iowa now will face No. 4 Minnesota, which beat No. 7 Virginia Tech 28-8. Iowa and Minnesota split 10 matches when they met on Jan. 26, but Iowa won the dual 16-15 on criteria.
