NORMAN, Okla. (AP) -- Romero Osby scored 17 points, all but two
in the second half, and Oklahoma extended its winning streak to
five games, beating Texas Tech 81-63 on Wednesday night.



Oklahoma (12-3, 3-0) remained tied atop the Big 12 with No. 4
Kansas and No. 16 Kansas State. The winning streak matches the
longest for the Sooners under second-year coach Lon Kruger.



The Sooners have won seven of their last eight games in Norman
against Texas Tech (8-7, 1-3). Dejan Kravic scored 20 points for
the Red Raiders, who have lost three straight games after
opening conference play by winning at TCU.



Osby and Buddy Hield combined to score all of the Sooners' 21
points in the first seven minutes of the second half, allowing
Oklahoma to stretch a five-point halftime lead to 13 points with
13:22 left. Texas Tech came no closer than six points after
that.
