NORMAN, Oklahoma - After a close-fought game, a late offensive push from the Sooners gave them an 80-71 win over rival Oklahoma State Saturday to split the regular-season Bedlam series and marking the Cowgirls third consecutive loss.

It was a hard-fought game for the majority of the 40-minute contest, with neither team holding more than a four-point lead for the majority of the second half, and nine lead changes in the first 13 minutes of the second half.

With seven minutes left to play, Liz Donohoe knocked down a jumper from the elbow to tie the game 59-59, to tie the game for the final time.

Kaylone Williams responded on the Sooners' next possession to retake the lead 61-59. Twenty seconds later, Sharane Campbell hit a three-pointer from the corner to push the Sooners' advantage to a full five points with 6:14 left on the clock.

The Cowgirls responded with a baseline jumper from Tiffany Bias to cut the lead to 64-61, but Campbell once again answered for OU with a jumper of her own and was fouled, converting on a three-point play to 67-61 with five minutes left to play.

On their next trip down the floor, Toni Young converted on a three-point play of her own to cut Oklahoma's lead to 67-64. However, OU immediately responded with a layup from Nicole Griffin to push the lead back to five points.

Two minutes later, the squads traded three-pointers, followed by a Campbell jumper to push the Sooners' lead to 74-67 with 2:39 left to play. At that point, it turned into a free throw contest, with the Sooners converting on six of their 10 attempts to close the game out.

Campbell set the pace for Oklahoma, turning in a double-double, finishing with 20 points and 12 rebounds, while Jelena Cerina and Aaryn Ellenberg both contributed 16 points in the win.

Donohoe and Bias led the charge for the Cowgirls, contributing 20 points each, with Donohoe grabbing eight boards and Bias dishing out six assists.

Oklahoma State will now take four days off before attempting to halt the skid, taking on the Texas Tech Red Raiders at 7 p.m. Wednesday at home.
