Following the cancelled 2020 season, the team announced in an email to season ticket holders on November 21, 2020, that the Washington Nationals were not renewing their affiliation with the Suns. Team General Manager Travis Painter noted "It is with a heavy heart that I’m writing to let you know that the Washington Nationals have decided not to renew their affiliation with the Hagerstown Suns. This brings 40 years of Hagerstown Suns baseball to a close." On December 9, 2020, the Nationals announced that the Fredericksburg Nationals, formerly the Potomac Nationals of Woodbridge, Virginia, would take over as the club's Low-A affiliate. As part of the minor league restructuring process, Major League Baseball did not invite the Suns to affiliate at any level or with any team, formally ending affiliated minor league baseball in Hagerstown.
