The Bruins wanted some good, old-fashioned Eastern Conference battles this weekend before starting to implement their plan of rest over the season’s final seven games, and that’s exactly what they got. They also banked four more points with a strong win over the Washington Capitals on Saturday, and a gritty, physical and nasty 4-3 shootout win over the Philadelphia Flyers on Sunday afternoon at the Wells Fargo Center. The Bruins came from a goal behind twice, but also allowed a Vinny Lecavalier game-tying goal with 24 seconds in the third period pushing things to the extra session. A Reilly Smith goal as the B’s final shooter iced the game for the Black and Gold, and Tuukka Rask made a season-high 49 saves. It was Smith’s second game-winning score in the shootout this season. The victory also gives the Bruins nine straight wins on the road, and a 13-0-3 record in their last 16 games away from the friendly confines of TD Garden. Things looked like they might be an uphill battle when the Bruins trailed by a 2-1 score after the opening 20 minutes following goals allowed to Vinny Lecavalier and Kimmo Timonen, and a revenge goal for Andrej Meszaros against the Philly team that traded him to Boston. But the Bruins pulled ahead for good on a couple of iffy goals allowed by Philadelphia goalie Steve Mason in the second period: a nifty power play backhander to the blocker side from Zdeno Chara, and a spinning Patrice Bergeron goal that completely caught the Flyers netminder by surprise.
