NORMAN, Okla. -- Whitney Hand scored 24 points and freshman Sharane Campbell scored the final seven points as Oklahoma overcame a 10-minute stretch without a field goal to beat No. 10 Texas Tech 71-68 Wednesday night.

Jordan Barncastle missed a contested 3-pointer from the right wing with two seconds left to try and tie it for the Lady Raiders (14-1, 2-1 Big 12), who suffered their first loss of the season after winning their first 14 games.

That left No. 1 Baylor, No. 5 Maryland, and No. 14 Wisconsin-Green Bay as the only unbeatens remaining.

The Sooners (10-4, 2-1) rushed off the bench in celebration when the buzzer sounded, celebrating a breakthrough win in a rare season that finds them outside the Top 25.

Full Scoreboard

Christine Hyde scored a career-high 21 points to lead the Lady Raiders. Kierra Mallard, Tech’s top scorer and rebounder, didn’t score over the final 31 minutes and fouled out with 2:33 remaining as the Sooners started to rally for the win.

After the Sooners survived a 10-minute stretch without a basket in the second half, Campbell put them within striking distance by converting a three-point play and fouling out Mallard in the process. Besides being Tech’s top scoring and rebounding threat, Mallard came up with two of her three blocks during the defensive

Campbell followed with a basket at the right block to put Oklahoma back ahead 69-68 with 2:06 remaining, and Tech didn’t score again.

Monique Smalls missed a 3-pointer, then made up for a Lady Raiders turnover by stealing the ensuing inbounds pass, only for Shauntal Nobles to commit an offensive foul while setting a screen on Tech’s inbounds play.

Joanna McFarland grabbed a key offensive rebound on Hand’s miss on the ensuing play, and DaShawn Harden set up Campbell for a layup with 12.7 seconds left.

The Lady Raiders trailed at halftime for the third time in their last four games but managed to push ahead as Hyde scored the team’s first 11 points after the break. Oklahoma briefly regained the lead after Hyde went to the bench, but then Chynna Brown hit a 3-pointer from the left wing to start a 12-3 run that put Texas Tech ahead to stay.

The Sooners didn’t make a basket for more than 10 minutes between Kaylon Williams’ layup just before the 14-minute mark provided a 51-49 lead and McFarland’s 3-pointer from the left side, bringing the Sooners back within 66-62.

Texas Tech never led by more than seven despite that strong defensive stretch.
