LUBBOCK, Texas (AP) — Will Grier threw for 370 yards with three touchdowns, Keith Washington thwarted a rally with 51-yard interception return for a score and No. 12 West Virginia held on for a 42-34 win over 25th-ranked Texas Tech on Saturday.
Marcus Simms had nine catches for a career-high 138 yards -- all in the first half -- for his third straight 100-yard game. The Mountaineers (4-0, 2-0 Big 12) scored 28 first-quarter points.
Texas Tech true freshman Alan Bowman, the nation's leading passer coming in, didn't return after getting injured in the first half when he was sandwiched on hits by Ezekiel Rose and Washington as he threw a pass.
Sophomore Jett Duffey had his first career touchdown pass and TD run filling in for Bowman as the Red Raiders (3-2, 1-1) stayed close after trailing 35-10 at halftime.
With Texas Tech driving for a potential tying score late in the fourth quarter, Duffey's second interception was a leaping grab by Washington , who returned it for a 42-27 lead.
"I focused all week on starting fast," West Virginia coach Dana Holgorsen said. "I guess I forgot to tell them there was a second half."
Duffey kept one drive alive with a 27-yard run on fourth-and-9 when he avoided three rushers on a blitz and cut inside another defender on the sideline when he was still short of the first down.
The Red Raiders pulled within eight when Duffey scored on a 3-yard run . The touchdown was set up by a 35-yard catch by Antoine Wesley , who made the grab after the ball bounced off Washington. Duffey threw for 172 yards and ran for 86.
The Heisman Trophy hopeful Grier had 198 yards passing in the first quarter with a 13-yard scoring toss to Gary Jennings and a 45-yarder to Simms for a 21-0 lead .
Kennedy McKoy capped the quarter for the Mountaineers with a 38-yard touchdown run with 4 seconds left to put the Mountaineers up 28-7. McKoy had 77 yards on 11 carries. West Virginia had 382 yards at halftime and finished with 489.
"They're really good on offense," Texas Tech coach Kliff Kingsbury said. "Their skill is tremendous. Their quarterback is a great player. They've got a great scheme. But we can't make it that easy."
