The Nationals and Braves will make up their game that was postponed Monday because of Washington's coronavirus outbreak as part of a doubleheader Wednesday.
Major League Baseball announced the change Monday while Nationals players were working out at Nationals Park.
Four players on the Nationals have tested positive for COVID-19 and seven more have been placed under quarantine after contact tracing determined they potentially were exposed.
The Nationals plan to add infielder Luis Garcia, outfielder Yadiel Hernandez, catcher Tres Barrera, right-hander Kyle McGowin and left-hander to their 26-man roster for Tuesday's season opener against the Braves, according to The Athletic.
