NORMAN – Oklahoma's guards made all of the difference in a 77-65 victory over Texas  Saturday afternoon, a result that gave the Sooners a season sweep of the Longhorns for the first time since 2005.

Isaiah Cousins led OU's backcourt assault with a career-high 24 points. The sophomore guard made seven of his 11 shots and eight of his nine free throws. He scored 17 in the second half as the Sooners stretched a 32-25 lead as wide as 72-55 with 4:15 remaining.

At that point, OU's guards had outscored Texas' 53-16.

Buddy Hield aided that discrepancy with 17 points. Je'lon Hornbeak replaced struggling point guard Jordan Woodard and added nine points on 4-of-6 shooting. Reserve guard Frank Booker contributed six points on a pair of 3-pointers.

The Sooners improved to 21-8 overall and 10-6 in the Big 12 Conference in maintaining their hopes for a second-place league finish. They're a half-game behind 10-5 Iowa State as the Cyclones play at Kansas State later Saturday.

Texas, which got 19 points and 14 rebounds from center Cameron Ridley but little from its backcourt, fell to 21-7 and 10-6.
