Brodeur made 26 saves in taking over sole possession of the postseason shutout mark from Patrick Roy. The 39-year-old goaltender also added his second assist of the series, giving him 10 for his career, four behind all-time leader Grant Fuhr.
The effort came two days after Brodeur was lifted after giving up three goals in 22:18 in a 4-3 loss.
CAPITALS 2, BRUINS 1
In Washington, playoff rookie Braden Holtby followed a shaky outing with a superb one by making 44 saves, and Alexander Semin scored the go-ahead goal, leading Washington to a victory over the reigning Stanley Cup champions that tied the series at two games apiece.
Marcus Johansson put the puck past Tim Thomas less than 11/2 minutes after the opening faceoff, but Boston’s Rich Peverley tied it later in the first period. Semin put Washington ahead for good with 1:17 left in the second on a power-play goal.
COYOTES 3, BLACKHAWKS 2 (OT)
In Chicago, Mikkel Boedker scored in overtime for the second consecutive game and Phoenix beat Chicago to take a 3-1 lead in the first-round series.
Boedker skated ahead of defenseman Nick Leddy and shoveled the puck under goalie Corey Crawford at 2:15 in the fourth game in a row that has gone to overtime.
Michael Frolik’s tap-in from the left side with 1:26 left in regulation tied it and marked the third time in four games the Blackhawks rallied to force overtime after pulling Crawford for an extra attacker.
