Nathan Walkup and David Loubeau each scored 16 points and No. 14 Texas A&M extended its winning streak to 12 games with a 71-48 victory over Oklahoma State on Wednesday night.

The streak is the third-longest in Texas A&M history and leaves the Aggies without a loss since a 67-65 defeat by Boston College on Thanksgiving.

The Aggies (15-1, 2-0 Big 12) led by six at halftime and didn't trail in the second half. The Cowboys cut the deficit to three points with about 15 minutes remaining, but the Aggies responded with an 8-1 run that included five points by Andrew Darko to push the lead to 51-41.

Oklahoma State (13-3, 1-1) got 11 points from Ray Penn. Marshall Moses had 10 points and 12 rebounds.

Walkup opened the second half with a 3-pointer and finished with four from long range to tie a career high.

Texas A&M led by 14 with about 5 minutes left before Dash Harris grabbed a rebound on a missed 3-pointer by the Cowboys and took it back for a monster dunk that brought the crowd to its feet. Harris clung to the rim to allow players to vacate the area, but nearly straddled Loubeau when he finally came down, with one of his legs landing over Loubeau's shoulder.

That dunk was part of an 11-0 run that included a 3-pointer by Harris that stretched A&M's lead to 71-48. Oklahoma State's last points came on a jump shot by Moses with almost 6 minutes remaining and the Cowboys missed nine field goal attempts after that to finish with their fewest points this season.

Their previous low came in a 56-51 loss to Virginia Tech.

Jean-Paul Olukemi, the Big 12 rookie of the week last week, had a tough night. He scored just one point and fouled out with 6 minutes remaining.

Texas A&M's leading scorer, Khris Middleton, had seven of the team's first 14 points but cooled off after that and finished with nine. Harris added nine points and seven rebounds.

The Aggies led by nine after a 3-pointer by Walkup with about 17½ minutes remaining. The Cowboys used a 6-0 run fueled by three points from Moses to get within 43-40 a couple of minutes later.

The Cowboys led by one after a dunk by Darrell Williams about 8 minutes before halftime. The Aggies used an 11-5 spurt in the next 4 minutes to take a 30-25 lead.

Oklahoma State scored four straight points after that to close the gap to one before a 3-pointer by B.J. Holmes and a basket by Loubeau pushed A&M's lead to 35-29 at halftime.

Oklahoma State scored the first six points of the game before Texas A&M answered with a 9-0 run to take a 9-6 lead with about 16 minutes left in the first half.
