SAN ANTONIO -- David Ash wasn't sure he would start the Valero Alamo Bowl. No one will remember after the way he finished Texas' rocky season with a validating and dazzling victory.

The sophomore threw a 36-yard touchdown strike to Marquise Goodwin with 2:24 left for the last of two fourth-quarter touchdown passes, stunning Oregon State and lifting the Longhorns to a 31-27 comeback victory Saturday night.

The Longhorns (9-4) never led before Goodwin scored his second touchdown on a deep post pattern, just a down after Texas converted a fourth-and-1 play to keep its chances alive.

"I guess in in every situation you have to be thankful," said Ash, who was pulled in a loss to TCU a month ago and wasn't immediately selected the starter for the Alamo Bowl. "I learned a lot at TCU. It was a tough situation I was in. I was just really thankful I got another opportunity to play a game I love."

With Texas down 20-10 at halftime, Longhorns coach Mack Brown said he told his players they would win.

"I told them this it wasn't going to be easy, but I told them this game was ours and we would win it," Brown said. "This one is really special."
