KALAMAZOO - The Northern Michigan University hockey team watched Michigan waste a five-minute man advantage with the game tied last weekend in Marquette.
This time, it was the No. 14-ranked Wildcats chance to squander a golden opportunity on the road.
Western Michigan killed off a five-minute major during the final seven minutes of the third period and the Broncos' Ian Slater beat NMU senior goaltender Reid Ellingson with a wraparound goal 26 seconds into overtime for a 3-2 victory and weekend sweep of Northern at Lawson Ice Arena.
Slater's goal was the lone puck Ellingson let past him after NMU starting goaltender Jared Coreau was yanked from the net by head coach Walt Kyle at the 10:08 of the first period.
Coreau allowed two goal on five shots while Ellingson, who started and made 29 saves in NMU's 4-2 loss Friday, went on to make 23 saves.
Northern (4-3-1 overall, 1-2-1 in CCHA) trailed No. 7 Western (5-0-3 overall, 3-0-1 in CCHA) after the first period, 2-0, but goals from senior Andrew Cherniwchan and sophomore Stephan Vigier in a span of 21 seconds during the second period knotted the game going into the third.
Western's Luke Witkowski opened the door for Northern with 6:44 to play in the game by drawing a five-minute major and game disqualification for checking from behind.
NMU sophomore Erik Higby, who assisted on both second period goals, had a solid look during the major, however, NMU was unable to get Higby's shot or any others on the power play past WMU netminder Frank Slubowski.
Northern failed to test Slubowski much for the second night in a row. The WMU freshman only needed to make 13 saves Saturday after making 12 the night before.
Northern was outshot 33-14 on Friday and 29-15 on Saturday.
Trevor Elias gave Western a 1-0 lead at the 8:05 mark of the first period and Brett Beebe scored his first career goal as a Bronco to put Northern down 2-0.
Northern returns home this weekend to host No. 4 Notre Dame at 7:35 p.m. on Friday and Saturday at the Berry Events Center.
