WACO, Texas — Brittney Griner had 28 points with 11 rebounds and top-ranked Baylor remained undefeated with a 71-44 victory over Oklahoma State on Wednesday night.

Baylor (16-0, 3-0 Big 12) never trailed, but led only by two at the half before a 20-4 run in the first 7 minutes of the second half to put the game out of reach. The Lady Bears won their 33rd consecutive home game.

Baylor pushed ahead 46-28 after consecutive baskets by Destiny Williams. After making a layup and then an Oklahoma State turnover, Williams missed badly on a break before she grabbed the rebound and followed up her own shot.

Williams finished with 11 points and 13 rebounds, her sixth career double-double. Griner had her 34th double-double, along with eight blocked shots, while Odyssey Sims had 21 points, eight assists and six rebounds.

Freshman Liz Donohoe led Oklahoma State (9-3, 1-2) with 19 points and eight rebounds. Toni Young had 13 points.
