MORGANTOWN, W.Va. (CBSDFW.COM/AP) — Texas Tech quarterback Jett Duffey continues to give West Virginia fits.

The junior moved the offense at will in the first half and the Red Raiders used a fast start to beat West Virginia 38-17 on Saturday, handing the Mountaineers their fifth straight loss.

Duffey threw for one touchdown to boost his total to 10 scores with two interceptions in his last five games after taking over in mid-September for the injured Alan Bowman.

“We came out with a great focus. We have to continue it,” Jett said. “I always believe in myself, I always believe that if I work hard and do what I need to do, then I will achieve what I want to achieve, no matter what’s in my way.”

Ta’Zhawn Henry and SaRodorick Thompson each had two first-half short scoring runs for Texas Tech, which broke a three-game losing streak and now has a bowl bid to fight for with three games left.

“A lot of people are counting us out,” said Texas Tech coach Matt Wells. “(We have) a little underdog mentality right now.”

West Virginia (3-6, 1-5) fell into a last-place tie with idle Kansas.

Texas Tech scored touchdowns on its first five drives and led 35-10 at halftime. Duffey accounted for 281 of Texas Tech’s 337 first-half yards. He took advantage of a decimated secondary with four first-half passes of 20 yards or longer, including an 81-yard scoring toss to a wide-open Dalton Rigdon.

“He’s really done a nice job of protecting the ball in the pocket better,” Wells said.

Duffey finished 24 of 34 for 354 yards.

“A frustrating day all the way around,” said West Virginia coach Neal Brown. “We got off to an extremely poor start defensively. We didn’t get pressure on the quarterback all day. He made a bunch of plays on us. He’s active. He got the ball out of his hand fast.”

A year ago, Duffey ran for 86 yards in a 42-34 loss to the Mountaineers in a game that West Virginia led by as many as 25 points.

On Saturday, the Red Raiders managed just a field goal after halftime and didn’t allow West Virginia to mount a comeback. The Mountaineers outgained Texas Tech 549-481 but squandered several scoring chances.

West Virginia turned the ball over on downs four times after incompletions deep in Texas Tech territory.

West Virginia’s Austin Kendall was intercepted twice, one of them into triple coverage that Texas Tech’s DeMarcus Fields caught in the end zone in the third quarter. Kendall also fumbled the ball away on fourth down as he was hit attempting a first-quarter pass.

Kendall finished 26 of 43 for 355 yards before being replaced late in the third quarter by Bowling Green transfer Jarret Doege, who made his season debut. Kendall and Doege each threw a touchdown pass.

West Virginia wide receiver Sam James caught 14 passes for 223 yards.

West Virginia’s losing streak is its worst since losing five straight in 2012.

The Raiders are now 4-5 and will play against TCU next Saturday at noon.
