FORT WORTH, Texas (AP) -- 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).
Iowa State won for only the third time in 33 road games against a Top 25 team since 1996. Barnett had another one of those wins, as a freshman last season at Texas Tech in his first career start.
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. They won their Big 12 debut at Kansas three weeks ago, and hadn't lost a conference game since Nov. 6, 2008 at Utah.
