Indiana's turnover woes returned and its road woes continued.
The Hoosiers, who had averaged just 9.6 turnovers in their previous five games, committed 23 miscues, including 14 in an 83-74 loss to Iowa at Carver-Hawkeye Arena on Thursday, leading to 34 Hawkeyes points.
The Hoosiers (12-4, 3-3 Big Ten) are 0-4 in true road games this season. They were outscored 42-26 in the second half after leading 48-41 at halftime.
The loss was similar to an earlier defeat at Syracuse in which Indiana turned the ball over 26 times on the way to a 112-110 defeat. Iowa's full-court press and zone defenses flummoxed the Hoosiers' point guards, Xavier Johnson and Rob Phinisee, who combined for eight turnovers against only seven assists.
The Hawkeyes (12-4, 2-3) took control with a 12-3 run early in the second half that erased a five-point deficit and left Iowa with a 61-57 advantage it never relinquished. Iowa's Tony Perkins scored six of his eight points during the run.
Indiana stayed in the game thanks to a big night from forward Trayce Jackson-Davis, who had 18 points on 6 for 8 from the field, 11 rebounds and five blocks.
Iowa forward Keegan Murray, the nation's leading scorer at 24.7 points per game entering the game, spent all night in foul trouble and had only 12 points. Murray's twin brother, Kris Murray, set new career-highs with 29 points and 11 rebounds.
Iowa had 11 offensive rebounds in the second half and a 10-1 advantage in second-chance points.
There was a scuffle as the teams walked to the locker room for halftime when it appeared Iowa's Connor McCaffery, son of Hawkeyes coach Fran McCaffery, approached Hoosiers coach Mike Woodson as the coach was talking to an official. More players, led by Indiana's Xavier Johnson, got involved and officials had to intervene.
