Ames, Iowa - Colt McCoy threw four touchdown passes and ran for another as No. 23 Texas ended its longest conference losing streak in 51 years with a 56-3 victory over Iowa State on Saturday.
McCoy followed up a strong performance in last week's loss to Oklahoma with an even sharper game, setting the tone for the Longhorns (5-2, 1-2 Big 12) by tossing a 58-yard touchdown pass on their first play.
Iowa State (1-6, 0-3) couldn't pressure McCoy or cover his receivers and suffered its worst loss since a 77-14 pounding by Nebraska in 1997.
McCoy, calling most of his plays without huddling, directed the Longhorns to touchdowns on his first five series and finished 23 of 30 for 298 yards and no interceptions.
He sat out the fourth quarter after ending his day with a flourish, slipping away from a potential sack and scrambling 44 yards for his first rushing touchdown of the season.
Texas broke a four-game Big 12 losing streak that dated back to last season and it came at the expense of one of coach Mack Brown's former assistants, Gene Chizik. Chizik was the co-defensive coordinator at Texas for two years before taking the Iowa State job last November, helping the Longhorns win the national championship in 2005.
