Eron Harris scored 21 points to lead the Spartans. They were playing their second game without injured star Denzel Valentine - their leader in scoring, rebounds and assists.
Peter Jok had 19 points for the Hawkeyes (10-3), which toppled a No. 1 team for the first time in 16 years.
Iowa never trailed in what turned out to be a surprisingly easy win over the Spartans (13-1). The Hawkeyes led by as much as 19 in snapping a nine-game losing streak against Michigan State.
