Oshie, who grew up in Everett, Washington, just a little over 100 miles south of Vancouver, got a big round of applause -- and a big hug from his uncle -- after his name was called out last.
The Capitals also shared a special video recapping Oshie's career on social media.
The heart and soul of this club since the day you joined.
During the game, fans at Rogers Arena gave Oshie a lengthy ovation when the milestone was announced to the crowd.
Oshie is in his ninth season with the Capitals after playing seven with the St. Louis Blues, who selected him in the first round of the 2005 NHL Draft.
The veteran forward and 2018 Stanley Cup champion is one of only 25 active NHL players to have over 300 career goals, a milestone he just reached last month.
