Norman, Okla. ? These Oklahoma Sooners sure can score. Then again, their defense needs a lot of work.

Jaison Williams scored 16 points, and Lawrence McKenzie added 13 to help No. 14 Oklahoma overcome an unusually poor defensive effort in an 81-73 victory Tuesday night over Tulsa.

“We just didn’t have a lot of defensive stops,” Oklahoma coach Kelvin Sampson said. “But we’ll break it down and work on it. Tulsa really shot the three tonight.”

The Sooners (3-0) outscored Tulsa 12-6 in the final 2:17 to seal the victory, helped by freshman point guard Drew Lavender’s layup that started the run and Williams’ quick putback after stealing an in-bounds pass.

Johnnie Gilbert punctuated the spurt by blocking a shot, then seconds later throwing down a two-handed jam to give the Sooners a 77-67 lead.

Tulsa was led by Jason Parker’s 20 points and Jarius Glenn’s 15.

These younger Sooners — the starting lineup has two true freshmen and two sophomores — look nothing like Sampson’s offensively challenged, yet defensively dominant teams that were led by All-American guard Hollis Price the past four years.

“We need to play better defense,” said junior guard Williams, himself a newcomer this season after transferring from the College of Southern Idaho. “We just need to put it all together.”

Tulsa (1-1) managed to shoot 59 percent, including 7-of-12 from three-point range, but couldn’t keep the quicker, more aggressive Sooners from controlling the pace of the game.

Kansas St. 92, Lipscomb 57

Manhattan — Tim Ellis had 16 points and Jeremiah Massey scored 15 to lead Kansas State. The Wildcats (2-0) shot 55 percent and never seriously were threatened. Kansas State shot 67.9 percent in the first half and held Lipscomb (0-2) to 34.8 percent.

The Wildcats cooled off slightly in the second half, shooting 43.8 percent. But they made 14 of 19 free throws in the half to hold off Lipscomb. After building a 46-25 lead at halftime, Kansas State started the second half making nine straight free throws to lead 57-32 with 16:07 left.

Stephen F. Austin 79, Baylor 57

Waco, Texas — Antonio Burks scored 28 points, including six three-pointers, to lead Stephen F. Austin. Jasen Gast scored 12 points, B.J. Banks added 11 and Hank Rivers scored 10 for the Lumberjacks (2-0). Terrance Thomas paced Baylor (1-1) with 24 points while Ellis Kidd added 13.
