The Hawkeyes (5-5) led 40-31 at halftime, but Iowa State went on an 8-0 run to take a 46-45 lead on an Anderson layup with 14:05 to go. Zach McCabe later sank a 3-pointer to put the Hawkeyes up 50-49 with 12:12 remaining, but Garrett's basket put Iowa State ahead for good 51-50 with 11:50 to go.

Matt Gatens led Iowa with 15 points, while McCabe scored 13, and Melsahn Basabe and Andrew Brommer scored 12 apiece.
