Freshman Joe Wieskamp tied a career high with 24 points and No. 23 Iowa shot 68 percent from the field in routing Illinois 95-71 on Sunday in Iowa City for its fifth straight victory.
Isaiah Moss scored a season-high 21 points and Luka Garza added 20 for the Hawkeyes (16-3, 5-3 Big Ten), who shot 34 of 50 from the field, a record for Carver-Hawkeye Arena.
They hit 12 of their first 14 three-point shots and 15 overall against the Illini (5-13, 1-6). Wieskamp finished 6-for-6.
"The only way you can explain it is to empower your guys to shoot it without hesitation," Iowa coach Fran McCaffery said.
Moss, Jordan Bohannon and Wieskamp buried consecutive threes to open the second half, and Moss capped that blistering run with a contested three-pointer to make it a 68-45 game.
Wieskamp and Moss combined to go 10-for-10 on threes during that stretch.
"That's being taken out to the woodshed," Illinois coach Brad Underwood said.
