Minnesota and Amanda Zahui B. finally provided Iowa a puzzle the Hawkeyes couldn't solve.
Zahui had a career-high 39 points and 29 rebounds as Minnesota knocked off No. 13 Iowa 93-80 Tuesday at Williams Arena in Minneapolis.
The loss snapped a four-game winning streak for Iowa, which dropped to 21-5 on the season and 12-3 in Big Ten play, and was just its second loss in its last 12 games.
Minnesota shot 50.7 percent from the field while improving to 21-6 on the season and 10-5 in Big Ten play with its fourth consecutive win.
Carlie Wagner added 17 points and went 5-of-6 from 3-point range as Minnesota hit 8-of-12 from beyond the arc as a team.
"We wanted to zone but we could not do that when they are shooting so well from 3-point range and we just didn't get out on their shooters," Iowa coach Lisa Bluder said. "It was a defensive intensity and a rebounding problem definitely tonight."
Led by Zahui B.'s Big Ten-record 29 rebounds Minnesota held a 53-35 rebounding edge.
Zahui B. made 16-of-31 field-goal attempts and scored 23 of her 39 points in the second half as Minnesota held off several Hawkeye runs.
"She is an incredibly strong player," Bluder said, "she was just shooting over us."
Samantha Logic led three Iowa players in double figures with 28 points and added 13 assists to notch the 28th double-double of her career.
"I thought she played really well," Bluder said of Logic. "I thought she tried really hard to keep us in this game."
Bethany Doolittle added 18 points and 11 rebounds for Iowa, which shot 38 percent from the field.
Melissa Dixon made five 3-pointers and finished with 17 points as Iowa went 11-of-35 from 3-point range.
Iowa got as close as 73-72 on a Logic 3-pointer with 7:32 left but Zahui answered with a pair of free throws and Shae Kelley followed with a basket to push the lead to 77-71.
The Hawkeyes never got closer than three points the rest of the game.
Iowa returns to action at 6 p.m. Saturday at Ohio State.
