STILLWATER, Okla. -- Markel Brown scored 21 points, Phil Forte hit four 3-pointers and had 19 points and Oklahoma State routed Texas Tech 79-45 on Saturday.

After losing the Bedlam rivalry game last weekend against Oklahoma, the Cowboys (12-4, 2-2 Big 12) called this "Commitment Week" and dedicated themselves to returning to the stiff defense that had propelled them into the Top 25 earlier this season.

They ended up holding Texas Tech (8-8, 1-4) to a season-worst 29 percent shooting. Jaye Crockett scored 11 points and Jordan Tolbert added 10 for the Red Raiders, who lost their fourth straight game after opening conference play with a win at TCU.

Oklahoma State stifled any chance for a Tech comeback with a 19-5 run just after halftime that featured a driving, right-handed slam and a 3-pointer from Brown. A pair of free throws from Forte extended the lead to 54-31 with 11:23 remaining.
