Geno Smith and No. 8 West Virginia turned their first trip to the University of Texas into a rollicking Wild West drama.
And now, two games into playing in a new conference, the Mountaineers look every bit like one of the teams to beat in the Big 12.
Smith passed for four touchdowns, Andrew Buie ran for 207 yards and two touchdowns, and West Virginia came away with another wild victory, this time taking down the 11th-ranked Longhorns, 48-45, Saturday night.
A week after West Virginia ran up 70 points on Baylor at home, the Mountaineers turned their first road game in their new league into another high-scoring, heart-pounding affair.
‘‘Every week, we’re going to go out and have fun,’’ Smith said after he and his teammates celebrated the win with several thousand West Virginia fans tucked into a corner of Royal-Memorial Stadium.
Smith, who has 24 touchdown passes this season without an interception, hit Stedman Bailey with a 6-yard score with 10:50 left to play. Buie’s second touchdown gave the Mountaineers a 10-point lead with 1:18 left.
But West Virginia (5-0, 2-0) didn’t seal the win until recovering an onside kick with 14 seconds left after Texas scored a touchdown on a pass from David Ash to Marquise Goodwin.
Joe Bergeron scored four touchdowns, all on short runs, for Texas (4-1, 1-1), which is 2-7 at home in conference games the since 2010. Texas has lost seven in a row to ranked opponents.
Smith was 25-of-35 passing for 268 yards in a game he had to be sharp. Texas hit him often and forced a second-quarter fumble that the Longhorns recovered for a touchdown.
Smith continues to make all the big throws when the Mountaineers need it, and he had to in a game where every possession was critical. West Virginia went 5 for 5 on fourth downs.
‘‘There weren’t a lot of times when we weren’t draped all over the guy when he was trying to throw,’’ Texas defensive coordinator Manny Diaz said. ‘‘You have to give him a lot of credit, his receivers a lot of credit.’’
Ash, the No. 2-rated passer in the nation behind Smith, was 22 of 29 for 269 yards and one touchdown.
South Carolina 35, Georgia 7 — Connor Shaw threw two touchdown passes and ran for another, Ace Sanders had a dazzling 70-yard punt return fpr a touchdown, and the No. 6 Gamecocks’ defense dominated the fifth-ranked Bulldogs in Columbia, S.C.
