FORT WORTH, Texas • Jared Barnett threw three touchdowns to Josh Lenz, who later had a scoring toss of his own on a trick play, and Iowa State won 37-23 at No. 15 TCU on Saturday to end the Horned Frogs’ FBS-best 12-game winning streak.
It was the first Big 12 home game for conference newcomer TCU (4-1, 1-1), which played without suspended quarterback Casey Pachall.
Barnett was 12 of 21 passing for 183 yards and ran nine times for 30 yards in his first start this season for the Cyclones (4-1, 1-1).
The Frogs had won a nation-best 25 conference games in a row, the first 24 while winning the Mountain West championship each of the last three seasons.
Lenz had TD catches of 51 and 74 yards in the first quarter.
Trevone Boykin started for TCU and was 23 of 40 passing for 270 yards with a touchdown and three interceptions.
