WACO, Texas (AP) -- Odyssey Sims was determined to be better for No. 7 Baylor this time against No. 12 Oklahoma State.
All the nation's leader scorer had to do was slow down a bit.
Two weeks after being held to a season-low 17 points against the Cowgirls, though she did have the game-winning points in overtime, Sims had 33 points on 14-of-19 shooting in the rematch, and the Big 12-leading Lady Bears won 81-64 on Sunday.
''They didn't do anything different. I guess I was more focused in on the last game, trying my best not to have another one of those games,'' Sims said. ''I was just very patient, letting the game come to me and score when I needed to.''
Sims was 7-of-27 shooting without making a 3-pointer on eight chances from beyond the arc in 42 minutes in Stillwater, OKla., where she converted a three-point play with 3.8 seconds left in overtime for a 69-66 win.
At home, where Baylor (20-3, 10-1 Big 12) has now won 33 consecutive conference games, Sims finished with three 3-pointers and scored 19 points by halftime. She matched her scoring total of the first game on a jumper with 1:23 left in the first half.
''Obviously this is a very difficult place to play,'' Cowgirls coach Jim Littell said. ''I've said since early in the season that Odyssey Sims is the best player in the country, and I think she showed that tonight. ... She's just a special player. We did a much better job on her up at Stillwater.''
Freshman Nina Davis both finished with 15 points and Makenzie Robertson, Baylor's other senior starter, had 11. Niya Johnson had 12 assists and Davis nine rebounds.
Robertson had eight points and Sims seven in a 17-4 run over a 5-minute spurt in the first half that put the Lady Bears ahead to stay.
Baylor clinched its 14th consecutive 20-win season, all since coach Kim Mulkey became the coach. The Lady Bears have won two national championships in that run.
Liz Donohoe had 22 points for Oklahoma State (19-4, 8-4). Tiffany Bias and Kendra Suttles each had 11 points while Brittney Martin had 14 rebounds.
There were five lead changes in the first 8 1/2 minutes of the game. The sixth - and last - came when Robertson made the first of consecutive 3-pointers.
Robertson had six 3-pointers in the previous game against the Cowgirls.
Davis had a layup that got Baylor to 21-19, then Robertson hit 3s on the next two Baylor possessions. Sims then scored the next seven Baylor points, on a jumper, two free throws and a 3-pointer.
'' I just went into the game and I was just very focused. My goal is not to score 30 points every game,'' Sims said. ''I just have the ball the majority of the time, but I was just making my shots today. I don't know what it was.
When Davis converted a three-point play soon after halftime, the Lady Bears had a 47-32 lead.
In the game at Stillwater, the Lady Bears had a 16-point lead early in the second half before Oklahoma State rallied to go ahead. Robertson's 3-pointer with 6 seconds left in the regulation forced overtime.
There was no comeback by the Cowgirls this time, down by 10 at halftime before a 25-point deficit that was their largest of the season.
''We just talked (at halftime) about ways to get Odyssey when they were hedging big on the on-ball screens, showing the post players different angles to set the screen,'' Mulkey said. ''Talked to a couple of them about situations that happened to them in the game. Again, making sure that they understand that it's our ball; the first 5 minutes, you don't let them think that they can get back in the ball game.''
