(KALAMAZOO) - Buffalo was finally challenged in conference play, and coach Nate Oats wasn't thrilled with how his team handled it. Jeremy Harris had 22 points and 11 rebounds, and the 16th-ranked Bulls held off upset-minded Western Michigan 88-79 on Tuesday night, but this game was close throughout after Buffalo won its first three Mid-American Conference games by a combined 70 points. Nick Perkins added 14 points for the Bulls (16-1, 4-0), who trailed by 11 in the first half and struggled to shake free of WMU until the very end. The Broncos (6-11, 0-4) went on a 15-0 run in the first half and led 33-22, but Buffalo rebounded quickly and led 43-39 at halftime. Buffalo pushed the lead to nine, but WMU answered with seven straight points to make it 77-75. Josh Davis scored 24 points for WMU.
