WASHINGTON (AP) Cameron Clark scored 22 points and pulled down 10 rebounds, helping propel Oklahoma to a convincing 81-66 victory over George Mason on Sunday in its first trip to the BB&T Classic.

Dominating work on the boards paved the way for the Sooners, who out-rebounded the Patriots, 51-29. Gonzaga transfer Ryan Spangler scored 13 points and had a game-high 13 rebounds. Buddy Hield added 12 points and 10 boards. Oklahoma made only 1 of 12 attempts from beyond the arc, but compensated with 48.3 percent shooting overall and overwhelming edges on points in the paint, 50-20, and on fast-breaks, 12-0.

Oklahoma (8-1) led all the way, getting little resistance from George Mason (5-4) which was led by Bryon Allen, who had 15 points. Guarded tightly by the 6-foot-7 Clark, Patriots' guard Sherrod Wright hit just 2 of 9 shots, scoring seven points, 10 below his team-leading average.
