AMES, Iowa (AP) — Mike Warren set an Iowa State freshman record with 175 yards rushing and two TDs and the Cyclones throttled Kansas 38-13 Saturday for their first win in a Big 12 opener since 2002.

Sam Richardson threw for 269 yards and a pair of touchdowns for the Cyclones (2-2, 1-0 Big 12). They notched their most lopsided win since blowing out the Jayhawks 34-0 in 2013.

Iowa State stretched its lead to 24-0 early in the second half on Warren’s 62-yard TD run, the longest of his career. Warren’s 7-yard score with 11:34 left made it 38-13.

Montell Cozart was 15-of-21 passing for 150 yards before leaving with a sprained left shoulder.

Marcquis Roberts had an 83-yard interception return for a score for Kansas (0-4, 0-1).
