With Smith leading the way, Maryland (18-4, 8-3 Big Ten) emerged from the break with a 14-4 run and held off a late surge by the Scarlet Knights to improve to 13-0 at home. Three free throws by Cowan put the Terrapins up 52-49 with 2:12 to go. Myles Johnson answered with a dunk, but the Scarlet Knights did not score again.
