Brad Marchand scored with 4:20 left in overtime and the host Boston Bruins beat the New York Rangers, 3-2, in the first playoff game in 40 years between the Original Six teams.
Marchand, Boston's top goal scorer in the regular season, got his first of the postseason on a pass from Patrice Bergeron. Marchand had carried the puck up the right side, passed it to Bergeron and kept going toward the net. Bergeron passed across the slot and Marchand tipped it past goalie Henrik Lundqvist from the left side of the crease.
Boston nearly won in regulation, but Johnny Boychuk's shot from the right point clanged off the left post with one-tenth of a second remaining. Then he hit the left post at the other end of the ice at 6:34 of overtime.
Zdeno Chara gave Boston a 1-0 lead at 12:23 of the second before Ryan McDonagh tied it with 1.3 seconds left in the period. Derek Stepan put the Rangers ahead 2-1 just 14 seconds into the third period, and Torey Krug tied it on a power play with his first NHL goal.
Game 2 of the best-of-seven Eastern Conference semifinals is set for Sunday night in Boston.
San Jose Sharks forward Raffi Torres was suspended for the rest of the Western Conference semifinal series against Los Angeles for a hit to Kings forward Jarret Stoll's head.
Torres was assessed a minor penalty for charging for the second-period hit Tuesday night in the Kings' 2-0 victory in Game 1. Under the Collective Bargaining Agreement, Torres is considered a repeat offender.
While playing for Phoenix last season, Torres received a 21-game suspension - initially 25 games - for a high hit on Chicago star Marian Hossa in the first round of the playoffs.
Torres was suspended for two games in January 2012 for charging Minnesota defenseman Nate Prosser and for four games in April 2011 for a hit to the head of Edmonton's Jordan Eberle while playing for Vancouver.
