The Hawkeyes improved to 14-0 overall and 9-0 in the Big Ten. The regular season title is Iowa's 11th since the conference started recognizing a dual champion in 1999.
"We getting ready for Oklahoma State, we're getting ready for the postseason, whether we get a trophy for this or not," said Iowa head coach Tom Brands. "We have to keep getting better and that's the bottom line. Our best wrestling is in front of us, but our best wrestling is coming out of us."
The Hawkeyes dominated the dual, winning the first nine matches and owning a 30-2 advantage in takedowns. Iowa won big and small, putting up bonus points in six matches and winning two more in sudden victory.
Spencer Lee won by fall at 125, Mitch Bowman won by technical fall, 27-9, at 174, and Austin DeSanto (133), Vince Turk (141), Kaleb Young (157), and Jacob Warner (197) all won by major decision.
Second-ranked Alex Marinelli won a 6-4 decision in a matchup of top three wrestlers. Marinelli used a reversal in the third period to force overtime, and finished on a single leg 35 seconds into sudden victory to top No. 3 Evan Wick.
Pat Lugo also won in sudden victory, scoring a takedown in with four seconds on the clock to defeat No. 19 Cole Martin, 3-1.
Cash Wilcke scored two takedowns in the third period to win 5-4 at 184. Wisconsin finally got on the board with a 1-0 win at heavyweight.
Iowa returns to the mat Sunday, Feb. 24 at Oklahoma State. The final dual of the regular season begins at 2 p.m. (CT) at Gallagher-Iba Arena in Stillwater, Oklahoma.
