The Hawkeyes jumped out to an early 8-2 lead as MSU struggled shooting from the floor in the early going.
The Spartans battled through a shooting slump that dipped to 21.4 percent at one point halfway through the first 20 minutes and kept the margin within five. Junior guard Klarissa Bell swished a half-court heave at the halftime buzzer to tie the game at 25 apeice.
Bell leads all scorers with 11 points and chipped in five rebounds. In her first game since Jan. 3, redshirt freshman Akyah Taylor provided a spark off the bench with four points.
Iowa’s leading scorer, 6-foot-5 center Morgan Johnson was held to seven points and nine rebounds in the first half.
