College Station, Texas ? Texas A&M kept pushing to the end. No. 13 Oklahoma State pushed harder.

John Lucas scored 27 points, and Tony Allen had 13 of his 21 in the second half for the Cowboys, who held off Texas A&M, 91-79, Tuesday night for their sixth straight victory.

The Cowboys shot 69 percent in the second half.

“We ran some special scoring plays, and we executed those well,” Oklahoma State coach Eddie Sutton said. “Something we need to work on is our defense.”

The Cowboys (16-2 overall, 6-1 Big 12 Conference) never trailed after the opening minutes, but the Aggies (7-11, 0-7) got within 73-68 with 5:51 to play before going on to their seventh straight loss.

“We just didn’t play defense at all, that’s about all you can say,” Aggies forward Nick Anderson said. “It’s tough when you turn the ball over, and they run a play and make it work.”

The Cowboys took a 53-39 lead early in the second half on a three-pointer by Lucas. The Aggies went on an 11-2 run to get within 55-51, but Oklahoma State answered with a run that included consecutive baskets by Janavor Weatherspoon to make it 64-53.

Lucas scored the Cowboys’ final six points.

“It’s a pretty big win for us,” Allen said. “We have some tough games coming up, and this was important for us to carry that momentum down the stretch to Iowa State. This was a credit to our practicing hard.”

Oklahoma State's Janavor Weatherspoon, right, stretches to block a shot by Texas A&M's Acie Law. OSU won, 91-79, Tuesday in College Station, Texas.

No. 19 Texas Tech 83, Baylor 63

Lubbock, Texas — Just hours after coach Bob Knight was reprimanded by the school for his public outburst at the chancellor, Texas Tech beat Baylor.

Andre Emmett scored 25 points for the Red Raiders, who snapped a two-game losing streak.

School officials reprimanded, but did not suspend, Knight for his spat with university Chancellor David Smith Monday.

As Knight left the court the crowd cheered loudly, and the Hall of Fame coach acknowledged them by raising his right hand in appreciation.
