HAGERSTOWN, Md. (AP) — A Hagerstown city councilman says a $15 million private donation toward construction of a downtown minor league baseball stadium isn’t assured.

Councilman Lewis Metzner told The Herald-Mail of Hagerstown on Wednesday that the city hasn’t confirmed that the prospective donor has the money. He says private sector funding is crucial to securing $10 million from the state for the $30 million project.

Metzner said earlier this month that the city had a verbal commitment from the Pennsylvania man, whose identity hasn’t been disclosed.

The stadium would house the Hagerstown Suns, a Class A affiliate of the Washington Nationals.

There is growing citizen opposition to spending public dollars on a ballpark to replace the 82-year-old Municipal Stadium.

Proponents say the stadium would help revitalize the downtown area.
