MINEOLA, N.Y. — A suburban New York official says the owner of an existing minor league baseball team has been chosen to operate a proposed second Long Island franchise.

Monday’s announcement is linked to Nassau County Executive Edward Mangano’s efforts to rebuild the Nassau Veterans Memorial Coliseum. Voters will decide Aug. 1 on whether to approve a $400 million referendum for the coliseum project.

Included in the referendum is a plan to build a $50 million minor league baseball park near the coliseum in Uniondale.

Mangano said Frank Boulton has been chosen to bring an Atlantic League team to Nassau. Boulton already owns the Long Island Ducks, who play in neighboring Suffolk County.

If the referendum passes, the project is still subject to a review by a state fiscal watchdog overseeing Nassau’s finances.
