Western Michigan sophomore goaltender Daniel Bellissimo turned aside 31 shots to blank host Lake Superior State, 1-0, as the Broncos swept the host Lakers to punch their ticket for Oxford, Ohio, to battle Miami. After 54 minutes of scoreless hockey, senior captain Mike Erickson beat LSSU junior goalie Jeff Jakaitis on the power play to propel the Broncos to the series win.
Jakaitis turned aside 26 shots in defeat.
