Playing as the No. 3 team in the country for the first time since 1987, Iowa came up with a clunker of a performance. Eighth-ranked Maryland had a lot to do with it.
Jarrod Uthoff and the Hawkeyes shot poorly for much of the game, and Iowa's nine-game winning streak ended with a 74-68 defeat in College Park, Md., on Thursday night.
Iowa (16-4, 7-1 Big Ten) went 5-for-24 from long range, was outrebounded 38-35 and had 11 turnovers compared to nine assists against the Terrapins (18-3, 7-2).
"I thought they were locked in," Iowa coach Fran McCaffrey said of Maryland. "They were locked in defensively, they were locked in on the glass."
Uthoff, who entered with a Big Ten-leading 18.9 points per game average, finished with nine points on 2-for-13 shooting.
Robert Carter Jr. and Rasheed Sulaimon each scored 17 points for Maryland.
No. 12 Michigan State 76, Northwestern 45: Denzel Valentine made five of the Spartans' season-high 16 three-pointers and Michigan State (18-4, 5-4) clamped down on the cold-shooting Wildcats (15-7, 3-6) in Evanston, Ill. Valentine finished with 19 points, seven assists and six rebounds. Northwestern shot a season-low 20.7 percent from the field.
Ohio State 68, Illinois 63: Trevor Thompson scored 16 points and the Buckeyes (14-8, 6-3) survived a furious comeback by the Illini (10-11, 2-6) to win in overtime in Champaign, Ill. JaQuan Lyle hit a pair of free throws with 14 seconds left in overtime to put Ohio State up 66-63 and Mickey Mitchell followed with a layup to ice the game.
