Chery was serenaded with a senior night twist of the Canadian national anthem before the point guard from Montreal made four of seven from 3-point range. Fellow senior Royce O'Neale hit consecutive 3s to break a 65-65 tie and give the Bears (23-9, 11-7) their first lead.
Devaugntah Williams was 8 of 9 on 3-pointers and scored a career-high 28 points for the Red Raiders (13-18, 3-15).
The victory assured Baylor no worse than the No. 4 seed for the Big 12 tournament next week. The Bears could finish as high as second.
