The day after the Washington Nationals won the 2019 World Series on October 30, 2019, in Houston, Texas, nine members of that championship team officially filed for free agency: pitchers Jeremy Hellickson, Daniel Hudson, Fernando Rodney, and Jonny Venters; infielders Asdrúbal Cabrera, Brian Dozier, Howie Kendrick, and Anthony Rendon; and outfielder Gerardo Parra. On November 1, the Nationals announced they would not exercise their share of the 2020 mutual option for first baseman Matt Adams, making Adams a free agent as well. The Nationals also declined club options over first baseman Ryan Zimmerman and catcher Yan Gomes, who also became free agents, on November 2. They exercised club options to keep pitcher Sean Doolittle and outfielder Adam Eaton under contract for the 2020 season. Hellickson chose to retire instead of pursuing another career opportunity, citing a nagging shoulder injury.
