BOSTON (AP) — This year, the Washington Capitals appear to have saved their best for the postseason. Joel Ward slammed home a rebound at 2:57 of overtime to give Washington a 2-1 victory over Boston in Game 7 of their first-round playoff series Wednesday night, sending the Capitals to Eastern Conference semifinals and ending the defending Stanley Cup champion Bruins' hopes of a repeat. Rookie Braden Holtby stopped 31 shots for Washington in the seventh one-goal game of the series.
