MORGANTOWN, W.Va. -- Ninth-ranked Oklahoma, continuing to make up ground for two September losses, overpowered No. 14 West Virginia 56-28 on Saturday night.

Behind 160 rushing yards from Samaje Perine and 147 by Joe Mixon, the Sooners (9-2, 8-0 Big 12) won their eighth straight game while defeating the Mountaineers (8-2, 5-2) for the fifth consecutive time.

West Virginia's Skyler Howard ran for two second-half touchdowns but not before throwing a pick-six interception that linebacker Jordan Evans returned 80 yards to make it 41-7.

The Mountaineers' Justin Crawford rushed for a career-high 331 yards on 24 carries.

Howard finished 12-of-27 passing for 191 yards, including a 37-yard touchdown to Ka'Raun White that pulled West Virginia within 41-28.

But the Sooners countered with a 65-yard drive capped by Baker Mayfield's 1-yard clincher. The quarterback tacked on another 1-yard score in the final 27 seconds.

Crawford lost a first-quarter fumble at the Sooners' 4. Another Mountaineers' threat ended at the Oklahoma 3 on a botched snap between Howard and center Tyler Orlosky.

Capitalizing on West Virginia red-zone fumbles, the Sooners marched 96 and 97 yards for second-quarter touchdowns. Mixon's 5-yard run stretched the lead to 28-0 before Perine's 9-yarder made it 34-0. Both Sooners running backs eclipsed the 100-yard mark in the first half, reducing the early workload for Mayfield.

Mayfield was only 4-for-7 passing at the break though two of his completions went for scores.

Mayfield's 5-yard pass to Jeffrey Mead made it 21-0, capping a 78-yard, nine-play drive. That followed Dede Westbrook taking a third-and-8 screen 75 yards by shaking free from linebacker Justin Arndt.

A fumbled punt at the West Virginia 34 set up Oklahoma's first score, a 2-yard run by Perine on a direct snap from the Wildcat formation.

Wet Virginia's 20-yard pass from Howard to Jovan Durante just 1:13 before half trimmed the deficit to 34-7.

With little to cheer in the first half, the near-sellout crowd at Milan Puskar Stadium rose to its feet when Oklahoma's Austin Siebert's missed extra point left the score 34-0. ... Mountaineers RB Kennedy McKoy left with an injury after his first carry.
