DALLAS -- John Lucas scored 11 of his 24 points during a 17-4 run in the first half, helping No. 6 Oklahoma State take control of what turned into a 76-57 victory over SMU on Monday night.
Oklahoma State coach Eddie Sutton won for the 759th time, tying Ed Diddle for eighth place on the Division I career list. Next up is Sutton's mentor, Henry Iba, who had 767 victories.
The Cowboys (4-0) were playing a third straight sluggish first half, trailing by four more than midway through the period, when Joey Graham hit consecutive jumpers to tie it at 15. Then Lucas scored three straight baskets, the last one a 3-pointer, to put Oklahoma State ahead for good.
After another basket by Graham, Lucas had a four-point play to give the Cowboys a nine-point lead that was never again threatened. His alley-oop pass to Stephen Graham coming out of a timeout midway through the second half began a 7-0 spurt that put Oklahoma State up 64-44, draining the Mustangs' hopes of coming back.
Lucas had three 3-pointers and hit all five of his free throws. The Cowboys were 14-of-14 from the line. They shot 56 percent from the field, including 13-of-20 in the second half.
Joey Graham scored 14 points, Stephen Graham had nine points and 10 rebounds and Ivan McFarlin scored 13 points. Daniel Bobik scored 11, all but two on 3-pointers.
SMU (2-1) lost for the first time under coach Jimmy Tubbs, who knows all about Oklahoma State after spending the past two seasons as an assistant at Oklahoma. The Mustangs could see this game as a sign of progress as they lost to the Cowboys by 35 last season and both teams return four starters.
Patrick Simpson led SMU with 20 points and Justin Isham scored 10. Bryan Hopkins was 1-of-11 from the field, missing all six 3-point attempts, and had just five points. Hopkins offset eight assists with six turnovers.
Oklahoma State wasn't playing at home, as it did against SMU last season, but it practically seemed like it as more than 60 percent of the crowd was rooting for the Cowboys, many of them wearing orange.
Oklahoma State hadn't played in Moody Coliseum in nine years, but the timing was pretty good as it gave star recruit Byron Eaton of Dallas a chance to watch his future teammates.
The Cowboys have held all of their opponents between 53 and 65 points.
