Ames, Iowa ? Freshman David Ash threw for 145 yards and his first two career touchdown passes and 17th-ranked Texas drilled Iowa State, 37-14, in the Big 12 opener for both teams.

Jaxon Shipley added 141 yards receiving and a TD for the Longhorns (4-0), who raced out to a 34-0 halftime lead to beat the previously-unbeaten Cyclones (3-1).

Ash threw a 48-yard TD pass to Mike Davis and a 40-yard touchdown to Shipley, and Josh Turner took a blocked punt back 34 yards to help Texas blow the game open in the second quarter.

Steele Jantz was 28-of-51 passing for 251 yards and a late TD pass for Iowa State, which looked nothing like the team that stunned Texas, 28-21, last season. The mistake-prone Cyclones lost two fumbles, and Jantz added a pick in the first half. They didn’t score until James White’s 2-yard TD run with 11:33 left.

The Longhorns have now won two straight on the road against teams that beat them in Austin last year. Texas thumped UCLA, 49-20, at the Rose Bowl two weeks ago.
