But the Caps went back in front off a bad turnover that turned into an easy Jakub Vrana goal from the slot.
Anaheim sent goalie Ryan Miller to the bench for an extra attacker in the final minute and a half and nearly got the equalizer before time ran out on them.
The Ducks were looking for payback after a 5-2 beating on November 18 in Washington, a game in which Anaheim and Washington combined for 50 minutes worth of penalties at the end of the second period. That included two fighting majors, a 10-minute misconduct, a game misconduct and a match penalty that led to a three-game suspension for Washington's Garnet Hathaway after an ugly spitting incident with Erik Gudbranson.
Gudbranson and Hathaway tangled in another fight in the third period, just one of many scuffles on a contentious and physical battle between the two combatants (which just happened to be Star Wars Night at Honda Center).
The Caps struck first on a one-timer from a sharp angle by Travis Boyd that got behind Miller, making his second straight start in place of John Gibson (flu-like symptoms). Miller had 33 saves on the night.
The Ducks came very close to tying the game in the closing seconds of the first and the opening seconds of the second, only to be thwarted by Caps goalie Braden Holtby each time.
Washington's vaunted power play (fifth-best in the NHL) came through yet again five minutes into the period when Evgeny Kuznetsov snuck a wrister through from the right wing.
Anaheim appeared to cut the lead in half on a Sam Steel one-timer on the power play, but Washington challenged on the grounds that Cam Fowler was offside prior to the goal, and it was disallowed.
The Ducks ultimately did get their first goal when Getzlaf put away a rebound from the slot with three minutes left in the period.
