WASHINGTON (AP) — Special teams made a special impact for the Washington Capitals in their first playoff game. With a perfect penalty-killing effort and a power-play goal by John Carlson, the Capitals beat the Philadelphia Flyers 2-0 Thursday night in Game 1 of their first-round series. Washington's penalty kill went for 4 for 4 and frustrated the Flyers, who lost second-line center Sean Couturier to an upper-body injury in the second period. Capitals goaltender Braden Holtby had seven of his 19 saves on Philadelphia power plays to pick up his third career shutout in the Stanley Cup playoffs.
