Seth Doege passed for six touchdowns and a career-high 499 yards while Texas Tech’s defense shut down Geno Smith and No. 5 West Virginia as the Red Raiders upset the Mountaineers, 49-14, on Saturday.

Red Raider fans stormed the field after the win, the most lopsided Texas Tech victory over a team ranked in the top five.

Texas Tech’s defense consistently stymied West Virginia’s offense. Heisman Trophy hopeful Smith completed 29 of 55 passes for 275 yards with one touchdown and no interceptions.

Meanwhile, the Red Raiders offense had no trouble.

“When you don’t have a pass rush it’s a lot easier to make your reads,” said Doege, who threw touchdown passes of 39, 19, 16, two, 29 and seven yards. He completed 32 of 42 passes, and the six touchdowns matched his career high. Darrin Moore caught three touchdown passes, which tied his career high.

Texas Tech (5-1, 2-1 Big 12) had 18 plays of 15 yards or more, including a 61-yard pass to Jace Amaro and a 53-yard touchdown run by SaDale Foster.

“I thought Seth did a tremendous job running our offense,” Texas Tech Coach Tommy Tuberville said. “He’s hard-nosed and he ran the ball.”

Amaro finished with five receptions for 156 yards.

The Mountaineers (5-1, 2-1) the previous week converted all five fourth-down tries in their 48-45 win at Texas, but against the Red Raiders they made just two of seven.

“Those guys did a great job of just attacking us,” Smith said. “They attacked us the entire game.”

On five of seven first-half possessions, the Red Raiders scored touchdowns.

The Mountaineers fell short of their scoring average (52) by 38 points and had just one touchdown in the second half, and that came when the game was already out of reach.

West Virginia’s Dustin Garrison scored on a two-yard run in the fourth quarter to make the score 49-14.

The Mountaineers had the third-worst pass defense coming into the game (336 yards) and didn’t do anything to improve on that.

The Red Raiders, meanwhile, started fast and kept the Mountaineers off balance.

By the time it was all over, they had 168 rushing yards on 29 carries and passed the ball 43 times.
