Norman, OK (Sports Network) - Alesha Robertson paced Texas Tech (12-8, 3-3) with 20 points and six boards but it was not enough as No. 6 Oklahoma edged the Lady Raiders, 86-81, at Lloyd Noble Center. Kendra Moore scored 13 of her career-best 20 points in extra time and Courtney Paris erupted for 22 points and 17 rebounds for the Sooners (16-1, 6-0 Big 12). Plainview product Chelsi Welch added 15 in the Oklahoma win. Five Lady Raiders ended in double figures including Jordan Murphree, who tallied 17 points. Chesley Dabbs put Texas Tech ahead, 65-63, with 1:15 remaining, but Oklahoma was able to tie the game in the final seconds of regulation on an Erin Higgins three-pointer to force overtime. Moore, a reserve guard, hit a layup with just over 30 ticks remaining in the second OT to put her club ahead by two. Britney Brown then hit three free throws down the stretch to help capture the win.
