Cowboys Bounce OU in Big 12 Opener, 77-56

John Lucas scored 22 points and Tony Allen added 20 to lead Oklahoma State to a surprisingly easy 77-56 victory over No. 11 Oklahoma on Wednesday night, the Sooners' second straight lopsided road loss.

Oklahoma State (11-2, 1-1 Big 12), bouncing back from an embarrassing loss of its own, never trailed and was firmly in control of this matchup against its longtime in-state rival.

The Cowboys, the Big 12's leader in shooting percentage, hit a sizzling 56 percent from the field while holding the Sooners to 35 percent, including 4-of-16 from 3-point range.

The orange-clad crowd of 13,611 was in a frenzy from opening tipoff -- hundreds of students slept in tents outside the arena the night before -- and the Cowboys responded with a 12-2 run to open the game.

Allen and forward Joey Graham carried much of the Cowboys' scoring punch early, sneaking inside the lane for putbacks and snatching away errant passes for thunderous dunks.

The Sooners, ranked No. 6 before Sunday's humiliating 86-59 loss at top-ranked Connecticut, were mired in the same kind of shooting slump that doomed them against the Huskies.

The bricks and turnovers kept on coming for Oklahoma (10-2, 0-1), which misfired on its first six shots of the second half to send them into an insurmountable hole.

Freshman guard Drew Lavender led Oklahoma with 15 points, the only Sooner to score in double figures.

Allen opened the second half with a thunderous one-handed dunk off a steal, keying yet another 12-2 spurt that ignited the crowd.

Lucas, a summer transfer from beleaguered Baylor, took over from there.

He nailed consecutive 3-pointers -- including one as he tumbled to the court with the shot clock expiring -- to give Oklahoma State a 68-50 lead with just over 4 minutes remaining, ending all chance of an Oklahoma comeback.

The Cowboys, 83-62 losers to Texas Tech in their Big 12 opener on Saturday, won their fourth consecutive game at home over the Sooners.

Ivan McFarlin had 17 points and nine rebounds for Oklahoma State.
