"I like bonus points. It makes it uneven and puts pressure on those guys," said Iowa head coach Tom Brands. "It doesn't have to be tight. Send messages to the rest of country. I like pins. I like bonus points."
The Hawkeyes scored bonus points in three matches before the break.
Spencer Lee and Austin DeSanto led off at 125 and 133, outscoring their opponents a combined 34-1 in six minutes, 19 seconds. In a matchup of top five opponents, Lee defeated No. 5 Devin Schroder 17-0 in 2:55. Lee scored a takedown 11 seconds into the match, forced a stalling point, and strung together four tilts worth 14 points.
DeSanto used three takedowns and 12 nearfall points to end his match 24 seconds into the second period, 17-1.
Max Murin earned a 6-1 decision at 141, Pat Lugo won by 8-0 major decision at 149, and Kaleb Young sent Iowa into the break with a 20-0 lead, topping No. 8 Kendall Coleman, 4-3.
"I'd rather get technical falls or pin guys, but we have to win close matches too," Young said. "Our coaches preach to us that the most dominant wrestlers win the close matches. I want to dominate guys, but I have to win the close ones too."
The second half opened with the "sugar bull" making its second appearance of the weekend at 165 pounds. Alex Marinelli turned his third takedown of the first period into his seventh fall of the season, flattening Tanner Webster in 1:51.
The final four bouts included two top-5 wins and a pin.
Michael Kemerer scored three takedowns in the final period to defeat No. 4 Dylan Lydy, 8-4, at 174. Jacob Warner opened the third period with four nearfall points, and closed it with a takedown in the final 34 seconds to win 8-2 against No. 2 Christian Brunner.
Abe Assad scored a takedown in the first period and another in the third to win, 5-2, at 184, and Tony Cassioppi put an exclamation point on the shutout with a fall two minutes into his 285-pound match.
"This is when it gets fun," Kemerer said. "Down the stretch we're going to need to win highly-ranked matchups. We got the shutout here. They had a lot of guys and thought maybe they could beat us, make it 5-5 or 6-4; we took 10 matches. We just have to stay in there and stay tough."
"Purdue has a good team this year," Warner said. "They are up-and-coming, but what we showed today shows what kind of team we are. We are the No. 1 team in the country and we're here to shut everybody out."
