OTTAWA (AP) - Jean-Gabriel Pageau got his first NHL hat trick Sunday night to lead the Ottawa Senators in a fight-filled 6-1 victory over the Montreal Canadiens. The teams combined for 236 penalty minutes and nine players were given a game misconduct. The Senators have a 2-1 lead in the best-of-seven series and Game 4 is Tuesday night in Ottawa. The third period started out with the Senators leading 2-1, but after Pageau's second goal of the night and a Kyle Turris goal at 7:00, emotions overflowed and a line brawl broke out at center ice. Pageau, who was born in Ottawa, scored his second of the game at 1:18 of the third period to give the Senators a 3-1 lead. Turris' goal, his first of the series, at 7:00 put the game out of reach. On the ensuing faceoff, four different fights broke out. The Senators ended up with the man advantage and Jakob Silfverberg scored on the power play as he beat Habs goalie Carey Price up high to make it 5-1 only 8 seconds after Turris' goal. More penalties were taken and at one point Ottawa was left with just five players on the bench, while Montreal had six. Pageau completed the hat trick, just the second player in Senators history to score a hat trick in the playoffs with less than two minutes left. Daniel Alfredsson also did it in 1998. Alfredsson scored Ottawa's opening goal and Craig Anderson stopped 33 shots. Price faced 30 shots. Rene Bourque scored for the Canadiens at 14:34 of the first. Captain Brian Gionta and Max Pacioretty, who both missed Game 2, were back in the lineup for the Canadiens. Pageau, with his first career playoff goal, gave the Senators a 2-1 lead early in the second as he slipped between defensemen P.K. Subban and Andrei Markov to beat Price over the shoulder. Pageau is not likely to forget the goal as he was hit in the mouth by Subban on the goal and lost a tooth. Players could be seen looking for the tooth on the ensuing goal celebration. The Canadiens had a couple of great chances to tie the game in the second, but came up short. Alex Galchenyuk was stopped by Anderson as he came racing in alone. And then with Montreal on the power play, Tomas Plekanec rang a shot off the crossbar. A physical first period ended with the teams tied 1-1. The Senators made the most of a 28-second two-man advantage as Alfredsson picked up his own rebound at his feet and quickly rifled it past the right of Price. It was the Senators' first power-play goal of the series. Montreal tied the game with a power-play goal as Plekanec found Bourque to create a 2-on-1 break. Bourque's shot seemed to throw Anderson off and he was unable to get over in time and could only watch as the puck trickled across the goal line. The Senators were forced to play most of the game with just five defensemen as Patrick Wiercioch, making his playoff debut, left the game midway through the first with a lower-body injury and didn't return. Notes: The Senators are without C Jason Spezza (back, indefinitely). D Eric Gryba served the second and final game of his suspension for his hit on Lars Eller in Game 1. Guillaume Latendresse and Andre Benoit were healthy scratches for the Senators in favor of Cory Conacher and Patrick Wiercioch. With Pacioretty and Gionta back in the lineup, Jeff Halpern and Gabriel Dumont were scratched for the Canadiens.
