John Gibson made 26 saves in his 20th start of the season.
Josh Manson, Sonny Milano and Vinni Lettieri scored for Anaheim. Despite playing without two top-line forwards in Adam Henrique and Ryan Getzlaf, the Ducks put 34 shots on net against of the NHL's top defensive teams.
Washington came out firing in the first period, peppering Gibson with early chances. Anaheim's netminder stood tall for most of the period, stopping 10-of-11 shots in the initial 20 minutes.
The Capitals broke through though for the game's initial lead when Wilson finished off a well-executed faceoff play. After an Anaheim icing call, the Capitals controlled a draw to Gibson's right. Ovechkin brought the puck to the middle of the ice, sliding a pass to Justin Schultz in the right faceoff circle. Schultz cut towards the net to draw the Ducks defense's attention before making a pass of his own to Wilson in front, who tapped it into the empty net for an early Washington lead.
The Capitals took that advantage into the middle frame, but held it for just nine seconds, as a back-and-forth period saw five goals, including tallies in the first and last minute.
The Ducks won the period's opening draw at center ice, getting the puck to Milano on left wing, who raced into the zone and rang a wrist shot off the post. Manson followed the play right to the crease, getting to the loose puck waiting back Capitals netminder Ilya Samsonov and tapping it over the goal line to tie the game.
