Matthew Tucker scored two touchdowns, Jaden Oberkrom kicked two field goals, and TCU’s defense forced four turnovers in dumping No. 18 Texas, 20-13, Thursday night in Austin to get the Horned Frogs their biggest win of their first season in the Big 12.

Tucker scored on runs of 1 and 2 yards and the Horned Frogs (7-4, 4-4) dominated the line of scrimmage, running the ball 48 times and passing just 10. TCU had two interceptions inside its own 10 to kill drives by Texas (8-3, 5-3) and picked up a fumble by Longhorns quarterback David Ash to set up Tucker’s second touchdown.
