MONTREAL -- Two first-period goals paced the Ottawa Senators to a 5-1 win over the Montreal Canadiens on Friday night in the first-round playoff series at the Bell Centre.

The win cut Montreal's lead to 3-2, with Game 6 scheduled for Sunday in Ottawa.

Right wingers Bobby Ryan and Erik Condra, left winger Mike Hoffman and defensemen Patrick Wiercoch and Erik Karlsson scored for Ottawa.

Defenseman Tom Gilbert had the Canadiens' goal.

Goaltender Craig Anderson stopped 45 shots for the Senators. Carey Price made 20 saves for Montreal.

The Canadiens came out firing, taking the first seven shots on goal before the Senators got their first nearly nine minutes in. But once they did, things fell in their favor.

For the fifth straight game in the series, Ottawa got on the board first. Hoffman led a rush through the neutral zone and fed Ryan inside the blue line. Ryan skated to the left circle and fired a shot past a screened Price to snap a 16-game goal drought at 9:29 of the first period.

Wiercioch put the Senators ahead 2-0 at 15:39. A Canadiens player got his stick on the rebound of a Jean-Gabriel Pageau shot and the puck found its way to Wiercoch, who moved inside the left circle before sending a shot through traffic.

It marked the first time in the series that either team led by more than one goal.

Karlsson added to Ottawa's lead on the power play at 14:29 of the second period. Center Kyle Turris picked up a loose puck in the slot and got it back to the Senators captain at the point. Karlsson then wired home a slap shot for his first of the series.
