"It was a highly competitive match," Iowa State head coach Bobby Douglas said. "I'm proud of the way we wrestled and we'll gain valuable experience from this meet as we continue our season."
Passolano opened the 69th meet between the two schools with a 12-8 decision at 174 pounds to remain undefeated at 3-0 in dual competition. Trevor Smith major decisioned Hawkeye Dane Pape at 197 pounds, using a three-point near fall in the second period and two stalling points against Pape in the third period to come away with bonus points and give ISU the lead, 7-3.
Nakamura, 2-1 on the year, built a 9-4 advantage on Magnini at 125 pounds before putting the Hawkeye on his back with 23 seconds remaining in the match.
"I was just going in trying to get the win or maybe a major decision," Nakamura said. "I was in the right place at the right time and I got the pin."
Top-ranked Nate Gallick remained unbeaten with a 2-1 overtime victory over eighth-ranked true freshman Alex Tsirtsis at 141 pounds. Gallick dealt Tsirtsis his first loss of his Iowa career and first official loss since junior high.
Trent Paulson came away with his fourth dual victory of the year at 157 pounds, decisioning Joe Johnston, 9-8. Paulson used 1:34 of riding time to his advantage as the match was tied at eight at the end of regulation. His brother Travis defeated Johnston last year in Ames, 7-4.
Iowa State heads out to Lincoln, Neb. on the 18th to compete with Dana, Wyoming and Findlay before competing at the Midlands Championships in Evanston, Ill. where it finished runner-up in 2003.
