DALLAS (Ticker) -- The John Lucas and Joey Graham tandem paid dividends again.
Lucas scored 24 points and Graham added 14 as No. 7 Oklahoma State won its road debut, a 76-57 victory over SMU.
In winning all three games of a season-opening homestand, the Cowboys got great production from their two stars. Lucas and Graham were the top two scorers in each contest, combining to score 40.7 points per game.
In this one, the two scored 21 in the first half to lead Oklahoma State to a 36-26 lead at intermission.
Graham did the damage early, scoring the Cowboys' first four points and getting two more baskets to tie the game, 15-15, with 7:51 left in the half. Lucas scored his first two points on a layup 38 seconds later to make it 17-15.
Lucas hit from the arc with 5:15 left to give Oklahoma State the lead for good, 22-19, and kick off 12-2 run. Lucas had missed his first three shots - each from beyond the arc.
The surge snapped the Cowboys out of another early slump, a problem that has bogged them down this season. Oklahoma State has outscored its opponents by an average of 18 points in the second half to recover from the slow starts.
Against the Mustangs (2-1), the Cowboys' lead never got smaller than seven after halftime as they rolled to their fourth straight win of 16 points or more.
The victory was the 759th of coach Eddie Sutton's career, tying him with Ed Diddle for eighth on the all-time Division I list.
Lucas and Graham were a combined 14-of-27 from the floor and contributed to a 14-of-14 effort from the line. Graham's twin brother, Stephen, scored nine points and swiped 10 rebounds off the bench.
Patrick Simpson scored 20 points for SMU, which lost its eighth straight to the Cowboys.
Mustangs' coach Jimmy Tubbs spent the last two seasons as an assistant at Oklahoma State.
