NORMAN, Okla. -- Buddy Hield scored 18 points, Isaiah Cousins added 12 and the Sooners pulled away for a 78-56 victory over Texas A&M-Corpus Christi on Thursday in a matinee that was rescheduled to start earlier because of concerns over bad weather.

Hield made eight of his 14 shots from the field and Cousins hit half of his 10. Overall, the Sooners (7-1) shot 45 percent as they wrapped up a three-game home stand, but the Islanders were even colder at 38 percent.

Texas A&M-Corpus Christi (3-7) was led by 12 points and a game-high 10 rebounds from freshman Rashawn Thomas, a 6-foot-7 Oklahoma City native making his college debut. Guard John Jordan added 11 points for the Islanders.

Oklahoma made nine of 22 3-pointers, five coming in the first half as the Sooners built a 42-24 lead. Guard Jordan Woodard hit two 3s as he and Hield led the Sooners with eight points each in the first half. Woodard finished with eight points.

With an undersized lineup, Oklahoma attacked early with a fast-paced offense.

Woodard was scoreless in the second half, but his 3-pointer with 7:38 left in the first half sparked a 16-2 run that put Oklahoma in control for good.

Six different players made a 3-pointer in Oklahoma's guard-heavy rotation that generated a steady offense in the first half. And the Sooners committed just nine turnovers, compared with 20 for the Islanders.

Cousins scored at least 10 points for the fifth consecutive game.

Oklahoma's shooting went cold to start the second half, but the Islanders were still unable to gain much ground. The Sooners maintained at least a 15-point lead throughout the second half, slowly putting the Islanders away.

Ryan Spangler and D.J. Bennett helped Oklahoma's cause on defense. Spangler led Oklahoma with nine rebounds, while Bennett added nine points and five blocked shots.

The game was moved back five hours as poor weather hit the Midwest.
