NORMAN, Okla. (AP) Oklahoma coach Sherri Coale said it was ''night and day.''
Exactly two weeks after getting blown out at Baylor, Kaylon Williams and Sharane Campbell-Olds each scored 15 points, and Oklahoma defeated the third-ranked Lady Bears 68-64 on Wednesday night to end Baylor's win streak at 25 games.
''For this team, we are so young,'' Coale said. ''We try not to talk about that a whole lot because I don't want them thinking they're not supposed to do things like this. But it's a significant step forward, especially the way we played the first time there.''
Baylor won the first meeting 89-66, but this time, Oklahoma took care of the ball and kept the Lady Bears out of transition. Peyton Little added 13 points and Gioya Carter had 12 for the Sooners (18-9, 12-4 Big 12), who clinched the No. 2 seed in the Big 12 tournament.
The Sooners outscored Baylor 18-10 from the free-throw line and remained undefeated at home.
''Total immersion,'' Coale said. ''That's what we got from everybody. People who came in the game, who didn't come in the game, people who played for almost 40 minutes. Total immersion. We didn't play perfectly, and they didn't play awful. And that's what makes it so great.''
Nina Davis had 20 points and 11 rebounds and Alexis Prince added 12 points for Baylor (26-2, 15-1), which only other loss this season came to Kentucky on Nov. 17. The Lady Bears were tied for the second longest winning streak in the country with Princeton, one behind UConn.
The Lady Bears had already clinched the conference regular-season title, and that showed in their effort.
''Honestly, we didn't come ready to play tonight,'' Davis said. ''We started out the game lackadaisical and that just can't happen in this part of the season.''
Niya Johnson, the nation's leader in assists, had just five. She had 17 in the first meeting.
The score was tied at 64 in the final minute when Williams was fouled. She made the second of two free throws to put Oklahoma up by a point with 30.5 seconds to play.
Baylor's Imani Wright missed an off-balance jumper, and Oklahoma's Gioya Carter rebounded, was fouled and made two free throws with 14.6 seconds left.
Wright missed a three, Dekeiya Cohen missed a putback, and Oklahoma's Campbell-Olds rebounded. She made one of two free throws to put the game out of reach.
Oklahoma rolled out to a 12-2 lead in the first five minutes. Baylor coach Kim Mulkey took all five players, including Davis, out of the game with 14:15 left in the first half, and Davis didn't come back for six minutes. Baylor rallied without her and trimmed its deficit to 16-15 before Oklahoma answered.
''I didn't think the first bunch had any energy, any enthusiasm, so give somebody else a shot, and they did an outstanding job,'' Mulkey said.
Oklahoma rallied and pushed its lead back up to 35-27 by halftime. Baylor trailed at the break for just the fourth time all season. The Sooners held Davis to six points on 2-for-6 shooting in the first half.
Davis got going early in the second half with two buckets that helped cut Oklahoma's lead to 35-33. A free throw by Davis tied the game at 45, and Baylor led by six before Oklahoma rallied in the final minutes.
Campbell-Olds, a senior, appreciated the moment.
''It's exciting to beat a team that I've never beaten before since I've been at Oklahoma, but I wouldn't say it's more about them. It's more about us.''
Baylor: Prince was issued a technical foul in the first half for throwing the ball hard toward an official. ... 6-foot-4 center Sune Agbuke fouled out with 6:24 remaining. She had seven blocks. ... Baylor blocked 10 shots as a team.

QUOTE OF THE NIGHT
Davis, on her team's approach: ''I guess you can say we kind of got relaxed. We just won the Big 12. Everybody kind of relaxed and laid back.''
Baylor, which entered the game leading the Big 12 in field-goal percentage, shot just 34 percent in the first half.
Baylor: At Iowa State on Saturday.
Oklahoma: Hosts Kansas on Saturday.
