FORT WORTH, Texas (AP) — Iowa State linebacker Jake Knott figures at some point people will quit referring to all these big wins by the Cyclones as upsets.
They got another one Saturday, ending the longest winning streak in major college football at 12 games with a 37-23 victory at 15th-ranked TCU.
This is the third season in a row the Cyclones (4-1, 1-1 Big 12) won on the road against a Top 25 team. And don't forget their double-overtime victory at home last year over Oklahoma State that cost the Cowboys a shot at the BCS national championship.
"I don't think they are so much upsets anymore," said Knott, the standout senior who had a late interception. "There's a lot of people now that respect us on a new level. We need to keep winning games like this to do that."
It was the first Big 12 home game for conference newcomer TCU (4-1, 1-1), which played without suspended quarterback Casey Pachall and had five turnovers.
Jared Barnett made his first start of the season and threw three touchdowns to Josh Lenz, who later had a scoring toss of his own on a trick play. David Irving, the Cyclones' 6-foot-7, 280-pound defensive end, returned an interception 20 yards for a touchdown.
Iowa State, which is home against No. 7 Kansas State next week, won for only the third time in 33 road games against a Top 25 team since 1996. All of those wins have come in the last three years in the state of Texas, including Barnett's first career start last season at Texas Tech.
"It feels great, but it doesn't mean nothing if we don't come back and finish strong the rest of the season," said Lenz, who had five catches for 147 yards.
Barnett was 12-of-21 passing for 183 yards and ran nine times for 30 yards. The touchdown throws of 51 and 74 yards in the first quarter put the Cyclones up 16-7, and he threw a 1-yarder to Lenz to start the second half.
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.
"You can't give up big plays on defense and you can't turn the ball over on offense," coach Gary Patterson said. "Real simple."
Dual-threat redshirt freshman Trevone Boykin took over for Pachall, the second-year starter who is suspended indefinitely after his arrest early Thursday on suspicion of driving while intoxicated.
