Peter Jok scored a career-high 29 points on Thursday night, and No. 9 Iowa shook off pesky Rutgers in the second half as it posted a harder-than-expected 90-76 victory on the road.
Jarrod Uthoff and Anthony Clemmons added 20 points apiece as the Hawkeyes (15-3, 6-0) won their eighth straight game and their 12th in a row in the Big Ten, dating to last season.
Iowa used a zone defense late in the first half in a 16-7 run that gave it a 45-37 lead, and it opened the game up in the second half with its long-range shooting.
