Oklahoma allowed the fewest points ever by a Big 12 team in a conference game, and the 24th-ranked Sooners defeated Texas Tech 81-36 on Wednesday night.
The Sooners eclipsed the league record of 37 points set by Texas against Oklahoma in 2004 and matched by Oklahoma against Texas A&M in 2008.
Ryan Spangler scored a season-high 20 points, Buddy Hield scored 15 points and Isaiah Cousins added 13 for the Sooners (13-7, 4-4 Big 12), who had lost 4 of 5, with three of the losses against ranked opponents.
Texas Tech upset Oklahoma 68-60 in Norman last year, but the Sooners had this game in hand quickly and held Tech to 21 percent shooting.
It was the worst margin of defeat in Texas Tech coach Tubby Smith's career. Tech (11-10, 1-7) was coming off a win over No. 9 Iowa State last Saturday that snapped a six-game losing skid.
