WACO, Texas (AP) -- Pierre Jackson scored 18 points, including
two 3-pointers and a tough inside basket in an 83-second span of
the second half when Baylor regained control on the way to a
64-54 victory over Oklahoma State on Monday.



Jackson, the Big 12's top scorer, had only five points in the
game's first 24 minutes before his quick eight-point spurt
pushed Baylor ahead by 10 points. Unlike their double-digit lead
in the first half, the Bears (13-5, 4-1 Big 12) held on this
time.



Le'Bryan Nash had 24 points for the Cowboys (12-5, 2-3),
including 10 in their 11-2 run going into halftime for a 28-27
lead.



Isaiah Austin (10 points, 14 rebounds, five blocks) and Cory
Jefferson (11 points and 11 rebounds) both had double-doubles
for the Bears.
