Brian Flynn scored a tie-breaking goal late in the second period and the Montreal Canadiens held on to edge the Ottawa Senators 4-3 on Wednesday night in a wild opening game of their first-round playoff series.
Flynn also had two assists for the first three-point game of his career.
Tomas Plekanec and Torrey Mitchell scored 15 seconds apart in a frenetic second period that saw five players get goals in less than five minutes. Lars Eller scored short-handed as part of the barrage.
Mika Zibanejad and Kyle Turris got power-play goals in the middle period for the Senators. Milan Michalek was credited with the game's first goal, which Montreal's Andre Markov tipped into his own net 12 minutes in.
Canadiens star defenseman P.K. Subban was given a five-minute major and game misconduct after slashing Ottawa rookie Mark Stone in the wrist midway through the second period.
