Brittney Griner had 18 points and seven blocks, Odyssey Sims and Terran Condrey scored 14 points apiece and top-ranked Baylor ran away in the second half and beat Oklahoma 89-58 on Thursday night.
The Bears (20-0, 7-0 Big 12) barely escaped with a one-point win in Norman last season on their way to the regular-season conference title but this time left nothing in question.
Coach Kim Mulkey called timeout with 3:14 remaining after a 12-0 run pushed the lead to 32, then sent her front-liners back onto the court. Griner hit her first 3-pointer of the season on Baylor's next possession, and that got the reserves off the Bears bench.
Destiny Williams added 13 points and Kimetria Hayden and Brooklyn Pope had 10 apiece as the Bears put six players in double figures.
Whitney Hand led Oklahoma (12-6, 4-3) with 19 points and seven rebounds.
