CHARLESTON, S.C. (AP) - Askia Booker had a career-high 23 points and Andre Roberson had 16 points and nine rebounds as Colorado won the Charleston Classic with an 81-74 victory over Murray State on Sunday night.

The Buffaloes (4-0) used an 11-1 run midway through the second half to break open a tie game and finish off their perfect trip South. Booker closed that run a 3-pointer and Colorado was ahead for good, 63-53 with 5:05 to go.

Murray State (3-1) was the last undefeated team in 2011-12, starting 23-0 on the way to a 31-2 record. The Racers got within five points several times down the stretch, including 79-74 on Isaiah Canaan's basket with 4 seconds left.

Booker was awarded the tournament's most valuable player.

Canaan led Murray State with 21 points, although just six of those came in the second half. Ed Daniel had 20 points and 10 rebounds.
