LUBBOCK, Texas — Redshirt freshman Jared Barnett threw for a touchdown and ran for another, and Iowa State shocked No. 19 Texas Tech 41-7 on Saturday night, a week after the Red Raiders won at Oklahoma.

Making his first start, Barnett’s mobility caused the Red Raiders defense fits. He rushed for 92 yards on 19 carries and completed 14 of 26 passes for 144 yards. His touchdowns were career firsts.

It was the largest margin of victory over a ranked team for Iowa State since the Cyclones beat No. 20 Nebraska in Ames by 22 points (36-14) in 2002.

Seth Doege completed 16 of 32 passes for a season-low 171 yards for the Red Raiders (5-3, 2-3). He threw two interceptions, lost a fumble and scored the Red Raiders lone score on an 8-yard touchdown run.

Iowa State (1-4, 4-4) rolled up 368 rushing yards against Texas Tech’s 105th-ranked rushing defense.
