KALAMAZOO, Mich. (AP) 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.

"It's as close as we've had in a while," Oats said. "It's not the worst thing to happen to us, but we've got to fix some stuff. We're not headed the right direction."
