Earlier in the night, he won what could be deemed the hockey fight of the year. Then, with just over seven minutes remaining, he made sure the Capitals would win as well.
Erskine delivered the win with a laser shot from the blueline past Ondrej Pavelec and into the net. David Steckel set up the goal by carrying the puck into Atlanta's zone and drawing two Thrashers players before laying the puck off for Erskine to take the open shot.
Steckel also added an empty net goal after winning a face-off with 0:37 remaining in the game.
Six different Capitals scored the six goals in this contest, with 14 different players scoring at least one point.
Erskine is very quietly having an excellent season for Washington. It might not be so quiet anymore though after his big day. He helped set up the tying goal yesterday with some strong defensive work, but tonight's performance will get him noticed across the league.
The win allowed the Capitals to extend their early lead in the Southeast Division to seven points. They will get a chance to pay back the Buffalo Sabres for yesterday's loss on Wednesday night before traveling down to Atlanta on Friday.
