CEDAR FALLS - Cael Sanderson finished his dual meet career at Iowa State in typical dominating fashion.
Sanderson improved to 152-0 in his career by scoring a 23-7 technical fall over Jason Payne as Iowa State beat Northern Iowa 25-12 on Sunday.
Ranked No. 1 at 197 pounds, Sanderson acknowledged the victory in his typical low-key fashion.
"It was a good match," he said. "I felt good, but there are a lot of things I still have to work on - everything really."
Sanderson's next match will be in the Big 12 tournament on March 9 in Norman, Okla. He has won three Big 12 and three NCAA championships. No one has won four NCAA titles while going unbeaten.
Seniors Joe Heskett, Billy Maldonado and Mark Knauer also won for Iowa State.
"It was a close match overall," Iowa State coach Bobby Douglas said. "There were several matches that could have gone either way. We've got a lot of work to do, but we have a lot of time to do it. It's back to the wrestling room on Monday."
Heskett, ranked No. 1 at 165, pinned Nate Lawrenz in 5:31 and is now 32-1 this season and 136-9 in his career. Maldonado earned a 17-4 major decision over Jon Garvin at 149 and Knauer beat Paul Hynek 3-1 at heavyweight.
Iowa State's Zach Roberson had a 25-10 technical fall over Mark Manchio at 133 and teammate Matt Veach beat Drew Kelly 11-4 at 157.
