STILLWATER, Okla. (AP) Freshman swingman Le’Bryan Nash scored a career-high 27 points, Brian Williams added a career-best 22 and Oklahoma State knocked off No. 2 Missouri 79-72 on Wednesday night. Nash, a McDonald’s All-American, scored 13 points during a 17-4 burst that sent the Cowboys into the lead in the final 4 minutes and the Tigers (18-2, 5-2 Big 12) didn’t have a response. Nash hit a jumper and a 3-pointer to get it going, then nailed another 3 from the left side to give the Cowboys (10-10, 3-4) a 65-64 lead with 3:23 to play. He connected on another 29 seconds later and ran to the opposite end of the court when Missouri called timeout to encourage a student section that was already hopping up and down to bring it on. When the clock hit zero, the students rushed the court and huddled around Oklahoma State’s players at midcourt. Ricardo Ratliffe had 25 points and 12 rebounds to lead Missouri.
