Terrence Shannon Jr. scored 25 points, Quincy Guerrier had 14 points and 13 rebounds, and No. 12 Illinois beat Iowa 73-61 on Sunday.

The Illini (23-8, 14-6 Big Ten) built a big early lead, then pulled away late in the second half after letting the Hawkeyes (18-13, 10-10) get within 59-53 with 6:58 left. Illinois, which finished three games behind Big Ten champion Purdue, will be the No. 2 seed in this week’s Big Ten Tournament in Minneapolis.

The Illini were coming off a 77-71 home loss to Purdue on Tuesday, and coach Brad Underwood said his team “kind of practiced angry for a couple of days” afterward.

The Illini led by 21 points before Iowa went on a 14-2 run, getting within 33-25 with 3:27 to play and trailing 39-29 at halftime.

The Hawkeyes continued to cut into the Illinois lead in the second half, getting within 51-47 with 11:15 to play. But the Illini scored six points in 70 seconds to get the lead back to double digits and kept control from there.

Shannon had 18 points in the first half and finished 10 of 19 from the field, hitting three 3-pointers.

Payton Sandfort led Iowa with 23 points, 19 in the second half. Josh Dix had 13 points.

Illinois held Iowa to just 35.4% shooting for the game.

Marcus Domask added 11 points for the Illini.

Illinois opens Big Ten Tournament play on Friday against either Iowa or Ohio State.
