The game set up as a bad matchup for the Cowboys and didn't differ from the pregame script, with the exception of Baylor's barrage of 3s.
The Bears entered as the Big 12 best from beyond the arc, averaging seven 3s a game. They more than doubled their average against the Cowboys, who ranked among the league's best in 3-point defense.
Pierre Jackson fired in five 3s, and Heslip and Quincy Miller each added three, as the Bears shot 51.7 percent from long-range (15-of-29).
“Oklahoma State just caught us on a bad day,” said Baylor coach Scott Drew.
Bad day for the Cowboys.
Even as OSU operated with some confidence and efficiency for the better part of the opening 20 minutes, Baylor built a 46-31 lead by halftime.
When the Bears got rolling, and rollicking, the end couldn't come quick enough, with the final 10 minutes turning into a highlight reel of dunks and alley-oops.
Baylor had four players finish in double figures scoring, with Miller leading the way with 21, while Jones added 19, Jackson 18 and Quincy Acy 15.
Beyond Brown and Page, who didn't score until the second half, there was little reliable production. Le'Bryan Nash managed just six points on 2-of-12 shooting.
