The Bruins evened their first-round series with the Red Wings at one game apiece with a 4-1 Game 2 victory over the Red Wings Sunday at TD Garden. After Detroit had shut out Boston in Game 1, the B’s got a pair of power play goals and scored two more at even strength. For the second straight game, Rask held the Red Wings to one goal. Justin Florek scored the Bruins’ first goal of the series thanks to a miscue from Red Wings netminder Jimmy Howard. With the puck at about the left faceoff dot, Howard skated out and tried to send the puck up, but instead he put it off Brendan Smith, resulting in a loose puck with the net vacant. Florek threw it straight at the net for his first career playoff goal. Reilly Smith made it 2-0 with a power play goal that came as a result of some tropically good work in front from Loui Eriksson. With Eriksson in front, Patrice Bergeron put a shot towards the net and Smith raced through in front to send it in. The second period saw the Red Wings find their legs, and they got some momentum back when Darren Helm went around Jarome Iginla and fired a shot that went off Luke Glendening and past Tuukka Rask. Milan Lucic made up for his line’s goal against, however, taking a pass from Torey Krug in the neutral zone and capping off a give-and-go with Iginla with a shot that went off Howard’s stick and in. Boston got some insurance in the third when Zdeno Chara buried a rebound from an Iginla shot for a power-play goal. Both Iginla and Krug had a pair of assists on the day.
