IOWA CITY, Iowa (AP) — Midway through the second half, an Iowa fan won a half-court challenge with a swish at the buzzer. The Hawkeyes' hot shooting must have been contagious.

Freshman Joe Wieskamp matched a career high with 24 points and No. 23 Iowa shot 68 percent from the field in routing Illinois 95-71 on Sunday 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 to set a record for Carver-Hawkeye Arena. They hit 12 of their first 14 3-point attempts and 15 overall to blow past the young but talented Fighting Illini (5-13, 1-6).

"The only way you can explain it is to empower your guys to shoot it without hesitation," Iowa coach Fran McCaffery said.

Iowa shot 68.4 percent in the first half to jump ahead 39-24. Moss, Jordan Bohannon and Wieskamp then buried consecutive 3s to open the second half, and Moss capped that blistering run with a contested 3 near the Iowa bench to make it a 68-45 game.

Wieskamp and Moss combined to go 10 for 10 on 3s during that stretch.

"That's being taken out to the woodshed," Illinois coach Brad Underwood said.

Iowa nearly broke the school record for 3-point percentage in a game, set 21 years ago at 75 percent against Northwestern, but walk-on Austin Ash missed a 30-footer in garbage time. The Hawkeyes finished 15 of 21 (71.4 percent) beyond the arc.

Ayo Dosunmu scored 15 points for Illinois. The Illini forced 15 turnovers, but they also let the Hawkeyes get tons of easy looks on 3s.

That's "a team I wouldn't want to play in the postseason because of their inside-out mentality and their ability to score in transition," Underwood said.
