They scored 10 goals Friday night, but Michigan needed only one Saturday night as Eric Werner's goal 2:05 into overtime snapped a scoreless tie and sent the Wolverines past Notre Dame and into the semi-finals of the CCHA Super Six next weekend.
It was also the final Michigan game at Yost Ice Arena this season.
"Tonight was a really good win for us going into the Super Six," said Werner. "You're going to be in overtime games. To win championships, you have to play overtime games and that was a good victory for us. Coach said that it was going to be a tougher game, a tighter game and we knew that we had to play better than last night."
Al Montoya made 19 saves for the shutout.
Friday night, U-M scored seven in the second period en route to a 10-1 win. Notre Dame actually held a 1-0 lead after the first 20 minutes.
Milan Gajic, Chad Kolarik and Brandon Rogers all scored twice and Gajic added two assists. Captain Eric Nystrom, Jeff Tambellini, Mike Woodford and Kevin Porter rounded out the scoring for Michigan.
Montoya played the first 39:45 and had 10 saves. Noah Ruden played the next 14:51 and stopped three shots and then Mike Mayhew finished up the final 5:09 and had to make just one save. The Irish also played all three of their goalies - Morgan Cey started, followed by David Brown and Rory Walsh.
"The puck went in," said Gajic of the second period. "We were pretty good on the power play. We had a couple of power-play goals there. If you have a good power play to start off with and you score a couple of goals there, it just keeps on going."
The Wolverines (28-7-3) will face the lowest remaining seed at 4:35 p.m. on Friday in the first semifinal at Joe Louis Arena.
