The Senators crashed the Montreal Canadiens' party and ordered up another round.

Oh baby, what a night.

The Senators, ranked No. 7 in the East, sent the heavily-favoured Habs to an early summer Thursday night with an easy 6-1 victory at the packed Bell Centre in Game 5.

Craig Anderson's stellar play to earned him his first playoff series win. Cory Conacher had two goals, while Daniel Alfredsson, Kyle Turris and Zack Smith also scored as Ottawa advanced past Round 1 for the first time since a trip to the Stanley Cup final in 2007.

"This year has been about proving people wrong and I've gotta say it feels pretty good," said defenceman Chris Phillips, one of only three players left from the roster six years ago.

Only Montreal's P.K. Subban was able to beat Anderson. Senators winger Erik Condra also chipped in with three points.

"We just beat the Montreal Canadiens. That's huge. I've gotta call my mom and tell her we just beat her team," Senators coach Paul MacLean said.

Determined to get this over quickly, the Senators will have a chance to sit back, relax and wait for their next opponent -- it will be the Pittsburgh Penguins if they win one of the next two against the New York Islanders.

"Montreal battled hard and played well. They probably deserved a better fate, but we stuck to it and kept the puck out of our net," said defenceman Erik Karlsson. "That was the key point for us. We didn't let them get any easy goals.

"We just kept going no matter what the score was or what time of the period it was."

The Senators had no desire to let the Habs off the ropes. Captain Daniel Alfredsson said the club wanted to deliver the knockout punch as quickly as possible.

Mission accomplished, but it helped the Habs had backup Peter Budaj in the nets for injured starter Carey Price.

"It was a great series for us in a lot of ways," said Alfredsson.
