AMES, Iowa (AP) — A little dose of confidence did wonders for Grant Rohach.
Buoyed by a decent performance in a loss to Oklahoma a week ago, the Iowa State freshman passed for a season-best 300 yards and two touchdowns and the Cyclones beat Kansas 34-0 on a frigid Saturday night for their first Big 12 victory.
"He left the Oklahoma game feeling better about his play," Iowa State coach Paul Rhoads said. "And on Tuesday, he was a confident and relaxed quarterback on the practice field. He was a different guy."
James White and Shontrelle Johnson each ran for a touchdown to top off their Senior Night and Cole Netten kicked two field goals for the Cyclones (2-9, 1-7), who broke a seven-game losing streak at home and sent Kansas to its 24th straight road loss.
Just one week after breaking a 27-game conference losing streak, the Jayhawks (3-8, 1-7) failed to capitalize on some early scoring opportunities and never got much going in the second half, either.
Rohach, who had not thrown a touchdown pass in his five previous games, finished 15 of 20 with one interception and scoring throws of 58 yards to Aaron Wimberly and 15 yards to Quenton Bundrage.
"I think the constant starts and the more reps I get, I get more confident out there," Rohach said. "And how well the guys played around me this whole week and into the game, it helps the confidence a lot."
It was the coldest game in Jack Trice Stadium history — 8 degrees at kickoff and 3 by the start of the second half — and the field was frozen and slick. But it didn't bother the Cyclones, who amassed a season-high 502 yards and recorded their first shutout since beating Northern Iowa 27-0 on Sept. 25, 2010.
Iowa State had not blanked a conference opponent since a 41-0 victory over Baylor in 2001 and had not won had home since beating Baylor on Oct. 27 of last season.
"It's been a long time coming," Johnson said. "The season didn't quite end up like we wanted, but this win was definitely a big thing for us. We celebrated. Water is all over the locker room right now."
Kansas' James Sims rushed for 114 yards in 21 carries to run his season total to 1,028 and become the first Jayhawk player with back-to-back 1,000-yard seasons.
But freshman quarterback Montell Cozart was ineffective in his second start, completing just 4 of 12 passes for 20 yards and one interception. He was replaced in the third quarter by previous starter Jake Heaps.
"I'm as disappointed this week as I was excited last week," Kansas offensive lineman Gavin Howard said. "This is one of the most disappointing losses I've ever had in my career here. I honestly don't know how it happened. We'll have to watch film to see exactly what is going on."
