OKLAHOMA CITY – Oklahoma provided a much-needed boost to its NCAA Tournament resume with a 65-51 win over No. 22 Texas Tech on Tuesday night at Chesapeake Energy Arena.

Kristian Doolittle scored 19 points and Brady Manek added 15 as the Sooners (17-11, 7-8 Big 12) snapped a three-game losing streak.

“Guys understand where we stand,” Oklahoma coach Lon Kruger said. “There are 30 or 40 teams that are in the same position as we are right now.”

Doolittle wore a mask after suffering a broken nose Saturday against Oklahoma State. It did little to slow him down as he made 9 of 15 shots and added seven rebounds.

Texas Tech guard Jahmi’us Ramsey, who entered the game averaging a team-leading 16.3 points, was scoreless and missed all eight shots.

“They stayed with him possession after possession and didn’t want to give him anything easy that could get him started,” Kruger said.

Kevin McCullar led the Red Raiders (18-10, 9-6) with 13 points.

Texas Tech was coming off a 30-point win at Iowa State and had won five of six, but the Sooners held the Red Raiders to a season-low 51.

“We played like a frustrated basketball team tonight,” Tech coach Chris Beard said. “When our shots were not going in early, I felt like we began to press. There are lot of ways to win basketball games when you don’t shoot well, but we didn’t do well creating other opportunities.”

The Sooners opened a 14-4 lead in the opening five minutes. Jalen Hill scored five straight points, and Oklahoma’s advantage grew to 21-6 just past the midway point of the opening 20 minutes. The Sooners led 32-22 at the break.

“I thought we came out attacking,” Kruger said. “The guys moved the ball, shared the ball — especially through the first half.”

Oklahoma built its cushion to 18 in the second half. Tech scrambled and cut the lead to 10, at 54-44, on McCullar’s driving layup with 3:39 to play. But the Red Raiders got no closer.

For the fourth time in five games, Oklahoma will face a ranked opponent when it travels to Morgantown on Saturday. The Sooners and No. 20 Mountaineers face off at 3 p.m. CT on ESPN2. The Sooners won the first meeting of the season, 69-59, on Feb. 8 in Norman.
