AUSTIN (September 8, 2012) -- Texas quarterback David Ash scored on a 49-yard touchdown run and had receivers turn short throws into two more scores and the No. 17 Longhorns routed New Mexico 45-0 Saturday night.

Ash's touchdown run came on Texas' sixth play from scrimmage. Mike Davis caught a 22-yard touchdown pass just before halftime. In the third quarter, Ash flipped the ball to Daje Johnson in the backfield and the freshman scooted around the end for a 45-yard TD.

Ash was 16 of 22 for a career-high 221 yards for Texas (2-0).

New Mexico (1-1) held the ball for nearly 20 minutes in the first half, but starting quarterback B.R. Holbrook was knocked out of the game in the second quarter after taking a blow to the helmet on a tackle.
