UMBC and Mount St. Mary's, playing in their NCAA Tournament opening rounds this afternoon and tonight, respectively, are hoping to accomplish what Belmont nearly did yesterday against Duke. The Bruins, a No. 15 seed, came within one point of knocking off No. 2 seed Duke. Holding a lead with less than a minute to play and three opportunities to go ahead at the end, Belmont should have won that game but let the Blue Devil get away, 71-70.
