STILLWATER, Okla. (AP) Le'Bryan Nash had 14 points and eight rebounds to lead No. 7 Oklahoma State to a 75-43 win over Delaware State on Tuesday night.
Markel Brown added 14 points for the Cowboys (10-1), Stevie Clark had nine points, and Marcus Smart and Michael Cobbins finished with eight apiece.
Kendall Gray led the Hornets (2-9) with 12 points and eight rebounds. Kendal Williams added 11.
Oklahoma State led 30-16 at halftime and went on an 18-2 to start the second half to pull away from Delaware State, which fell to 0-9 against Big 12 Conference opponents.
It was the Cowboys' fourth straight win since a 73-68 loss to Memphis on Dec. 1, and the third straight game they held an opponent under 20 points in the first half. The Hornets hit 6 of 25 shots over the first 20 minutes and were 16 for 56 for the game.
The deliberate, shot-clock-eating offensive system employed by Delaware State coach Greg Jackson worked for 20 minutes, limiting Oklahoma State to a season-low 30 points in the opening half. Since giving up 32 first-half points to Memphis on Dec. 1, the Cowboys have held their last three opponents under 20 points in the opening 20 minutes: South Carolina (15), Louisiana Tech (18) and Delaware State (16) on Tuesday.
Smart, the Big 12's leading scorer, did not score in the first half, but ignited the early second-half run with a pair of steals followed a dunk and 3-pointer. Brown's long-range 3-pointer put the hosts up 54-30 and the final 8 minutes saw plenty of dunks, long-range shots and sloppy play by both teams.
OSU out-rebounded the Hornets 39-34 and shot 17 more free throws, hitting 17 of 24. Smart had three steals, part of 10 for the hosts, and Kamari Murphy had four of the Cowboys' 10 blocked shots.
Despite another lopsided win, Oklahoma State continued to struggle from 3-point range. OSU entered Tuesday 10 of 47 (21 percent) over its last three starts. That trend continued as the Cowboys were 0 of 8 in the first half and 6 for 23 for the game. Phil Forte was 1 of 10; the rest of the team was 5 of 13.
