LUBBOCK, Texas (Ticker) -- There was no clock controversy, no overtime and no shot for Oklahoma.

Andre Emmett scored 21 points as No. 18 Texas Tech won its 11th straight game, continuing the 21st-ranked Sooners' slide with a 67-47 Big 12 Conference rout.

Last season, Oklahoma defeated Texas Tech three times, including a pair of overtime victories. The Sooners gained a memorable win in Norman when the clock started late to allow Hollis Price to drain a jumper that sent the game into an extra session.

Red Raiders coach Bob Knight complained that Oklahoma should have forfeited the game, drawing the ire of Sooners coach Kelvin Sampson. The bad blood carried over to the offseason, when an ethics meeting convened by NABC president Sampson was not attended by Knight, who claimed "I would have rather listened to Saddam Hussein speak on civil rights than to some people speak about ethics."

Oklahoma (10-4, 0-3 Big 12) never had a chance and dropped its fourth straight, its longest slide since the 1998-99 season. The Sooners are 0-3 in conference play for the first time since the 1980-81 season, Billy Tubbs' first.

Texas Tech (15-2, 3-0) overcame 11 first-half turnovers for a 27-19 lead at the break. After the Red Raiders cleaned up their game, they ran the youthful Sooners out of the building.

"I guess we were a little excited in the first half (with) 11 turnovers," Emmett said. "We had to calm down and get the victory."

The Red Raiders scored eight of the first 11 points of the second half, taking a 35-22 lead on Devonne Giles' layup with 16:44 left. Giles scored 10 of his 12 points after halftime.

"Giles was a major factor in the second half," Knight said. "He had a tough time holding onto the ball in the first half."

Freshman Jarrius Jackson's fast-break layup capped a 9-0 tear that established a 49-26 lead with 11:33 to go and prompted Sampson to take his fifth and final timeout.

Texas Tech limited Oklahoma to 33 percent shooting, including a 3-of-19 performance from the arc. The Sooners' three-guard lineup of De'Angelo Alexander and freshmen Drew Lavender and Lawrence McKenzie combined to make 5-of-21 shots for 15 shots.

"I'd have to say that overall our defensive play was what we're trying to get," Knight said. "Before the season, I commented that our goal was to be a better defensive team than we were last year and I think we're getting there."

The only suspense in the contest was with the post-game handshake. Knight and Sampson exchanged a quick shake before turning away from each other, similar to what they did after the Sooners' overtime victory last season in the Big 12 tournament semifinals.
