NORMAN, Okla. (AP) -- Senior Kendra Moore has had few starring moments during her Oklahoma basketball career.
The Sooners are glad that the backup point guard picked Monday night to command the spotlight.
Moore scored 13 of her career-high 20 points in extra time as No. 6 Oklahoma held on to beat Texas Tech 86-81 in double overtime.
Courtney Paris recorded her 45th straight double-double, finishing with 22 points and 17 rebounds for Oklahoma (16-1, 6-0 Big 12), which extended its winning streak against conference opponents to 25 games.
But during the overtimes, Moore -- not Paris -- became the Sooners' go-to player.
Moore, who entered the game averaging 3.6 points, scored all seven of Oklahoma's points in the first overtime. With the game tied 81-81 in the second OT, it was Paris handing the ball off to Moore on a pick-and-roll and Moore slicing through the lane for a layup with 34.4 seconds left.
At 5-foot-5, Moore "may be the smallest person in the building," Paris said, "but she took the ball to the hole and made it count."
At the other end, Oklahoma's starting point guard, Britney Brown, stole the basketball from Texas Tech freshman Jordan Murphree as she rose to shoot. Brown hit two free throws with 11 seconds left -- her first points of the game -- and added another free throw in the final second to seal the win.
Moore's heroics against the Lady Raiders drew comparisons to the last game in which she stole the spotlight -- a 73-70 win last season at then-defending national champion Baylor, in which she hit two 3-pointers in the final 16 seconds.
"I thought that [Moore] really took it to us at the end," Texas Tech coach Kristy Curry said. "I hope that the freshmen that she took it at will not let that happen again in the next couple of years. ... We are searching for that defensive stopper on the perimeter. Tonight we didn't have one when it really mattered."
Five players scored in double figures for Texas Tech (12-8, 3-3), led by Alesha Robertson, who finished with 20. Six-foot-6 Patrice Edwards added 12 points and 10 rebounds for the Lady Raiders.
It was Oklahoma's first double-overtime game since Dec. 21, 2000, when the Sooners beat San Diego. Texas Tech played its last two-overtime game on Feb. 23, 2000, a win over Texas.
Oklahoma struggled with turnovers for much of the game, finishing with 21, and never led by more than eight points. Paris went just 9-of-24 from the field, sitting out nine minutes of the second half. She did not score in the game's final 14 minutes and missed five shots in the overtime periods.
The Sooners led by six with three minutes left in regulation, but Texas Tech rallied to go ahead 67-63 with 44.2 seconds left, and Oklahoma needed a 3-pointer by Erin Higgins with 7.6 seconds left to forge a 68-68 tie.
"It's one thing to execute that play and get the shot," Oklahoma coach Sherri Coale said. "It's another thing to make it. Higgins stepped up and did what a senior shooter does. She knocked the bottom out of it."
Texas Tech's Chesley Dabbs, who scored 13 points, missed a 10-footer at the buzzer.
The Lady Raiders fell behind by three points early in the first overtime but took a 75-73 lead on a 16-foot jumper by Dabbs with 1:16 left. Moore tied it seconds later on a drive at the other end.
"I realized they weren't guarding me and I was able to drive to the hole," Moore said. "It was all about being patient. Once I realized I could get to the hole, I took advantage of the opportunity and made the most of it."
After a Paris miss, Texas Tech had another chance to win, but she altered a jumper by Dabbs and the ball went out of bounds with eight-tenths of a second left. Paris stole the ensuing inbounds pass and her heave from 70 feet hit the rim and bounced away.
"When you get that strong punch [from opponents] every single night out, you're going to have some games like this," Coale said. "I think it's a great reflection of our intestinal fortitude ... that we're able to handle that and find a way to win.
"Throughout a season you have peaks and you have valleys. If you can win when you're in the valley, then you've got something special going on."
Oklahoma outrebounded Texas Tech 49-35. Welch added 15 points for the Sooners, while Ashley Paris had 10.
Murphree scored 17 points for Texas Tech and Raquel Christian added 14.
The game was delayed for eight days because of weather and was the Sooners' first at home Jan. 3. Oklahoma is in the midst of a stretch during which it will play five games in 11 days.
