Iowa (14-8 overall, 5-4 Big Ten) broke open a close game with a 12-0 run to end the first half. The Hawkeyes enjoyed a 31-21 lead at the break. Michigan cut its deficit a few times after the intermission but the visitors always delivered the necessary counter punch.
Forward Jarrod Uthoff led the winners with 16 points (7-10 from the floor) and nine rebounds. Center Adam Woodbury played one of his best games of the season for Iowa with 11 points, seven rebounds and a team-high six assists. Mike Gesell (14), Aaron White (13) and Peter Jok (10) also scored in double figures for the Hawkeyes.
Iowa shot a blistering 32-51 (62.7 percent) from the floor and outrebounded Michigan, 33-17. Each team only committed six turnovers.
Coach Fran McCaffery and his staff designed a strong game plan for the winners. Their 2-3 zone frustrated the Wolverines.
The Hawkeyes prefer man-to-man defense, and it might have made sense to match up against a strong outside shooting team. However, their zone Thursday was designed to extend to the arc. They utilized their length and height advantage against a team with no real offensive threat on the interior.
Freshman Aubrey Dawkins, the son of Stanford Coach Johnny Dawkins, led the Wolverines (13-10, 6-5) with 16 points, connecting on 4 of 7 three-point tries. The rest of the team shot 3 of 17 from behind the arc.
Iowa returns home on Sunday (2:21 pm CT, BTN) for a meeting with No. 17 Maryland.
