The Hagerstown Flying Boxcars hope to be a hit with the community when they begin their inaugural season in the Atlantic League of Professional Baseball this year. Meritus Health has joined in the effort, hoping to help make it a grand slam. During a press conference and private event at Seven Ten in Hagerstown on Tuesday evening, Blackie Bowen, of the Flying Boxcars ownership group, announced the team’s naming-rights partnership with Meritus.
