NORMAN, Okla. (AP) -John Roberson scored 22 points, Darko Cohadarevic added 12 and Texas Tech barely held off a second-half rally to beat Oklahoma 72-71 Tuesday night, snapping the Sooners' 31-game home winning streak against unranked opponents.

Willie Warren and Tommy Mason-Griffin each missed potential game-winning 3-pointers in the final 5 seconds as Oklahoma (13-10, 4-5 Big 12) absorbed a disheartening blow to its postseason hopes.

Texas Tech (16-7, 4-5) built a 12-point lead early in the second half and was able to stave off a series of comebacks to break a six-game losing streak and sweep the season series from the Sooners.

Warren had 18 points while playing his most significant minutes since missing two games with a sprained ankle, and Tony Crocker added 16 points and 11 rebounds for Oklahoma.

The Sooners played without suspended freshmen Steven Pledger and Andrew Fitzgerald.
