STILLWATER, Okla. — Perry Jones III had 16 points and 11 rebounds, Quincy Acy provided the go-ahead basket and a key offensive rebound down the stretch and No. 6 Baylor edged Oklahoma State 64-60 on Saturday.

The Cowboys (11-12, 4-6 Big 12) rallied from a nine-point deficit to take a 57-56 lead on Keiton Page's wide-open 3-pointer from the right wing with 1:42 to play.

After a timeout, Acy answered at the other end with a layup set up by Pierre Jackson's drive. Acy also grabbed the rebound when Brady Heslip missed the front end of a one-and-one free throw opportunity with 6.8 seconds left, allowing Anthony Jones to hit two foul shots to close it out for Baylor (21-2, 8-2).

Brian Williams scored a career-high 23 points for Oklahoma State, which was bidding to win back-to-back home games against top-10 opponents.
