Peter Jok scored 23 points and Iowa upset 25th-ranked Iowa State 78-64 on Thursday, snapping a three-game losing streak against its instate rival.

Isaiah Moss had 14 points to help the Hawkeyes (5-5) beat a Power Five opponent for this first time this season.

Iowa shot 59 percent in the first half, including 6 of 10 from 3-point range, and jumped ahead by as much as 46-29. The Cyclones (6-3) slowly chipped away at that deficit in the second half, but a 7-0 run by the Hawkeyes after Iowa State got to 60-53 finished them off.

Matt Thomas scored 14 points to lead the Cyclones, who were just 8 of 30 from 3-point range. Ball movement was again an issue for Iowa State, which had just nine assists on 25 made baskets — although it did miss about a dozen layups.
