As Markel Brown steamed down the court in the final seconds of overtime, he looked at the clock once, then twice, and decided to try to get to the rim. He did, just in time for Oklahoma State. Brown's lay-in with two-tenths of a second left -- which followed a blocked shot at the other end by teammate Michael Cobbins -- lifted No. 22 Oklahoma State to a 69-67 win over Baylor on Wednesday night and extended the Cowboys' winning streak to four games.
