Nicklas Backstrom scored 2:56 into the second overtime to lift the Washington Capitals to a 2-1 win over the Boston Bruins in Game 2 of the Eastern Conference quarterfinal series at TD Garden.

Backstrom beat Tim Thomas from the left circle -- nearly the identical spot on the ice where Boston's Chris Kelly notched the overtime-winner in Game 1 -- with a wrister off a feed from Marcus Johansson.

The series shifts to Washington for Game 3 on Monday.
