Gerardi, who died in January, was involved in Huntington softball for more than three decades as a player, manager, organizer and president of the Huntington Men’s Softball League.
In July, the Town Board voted to dedicate Field No. 4 in his memory.
Huntington Supervisor Frank P. Petrone joined Council Members Mark Cuthbertson and Mark Mayoka, other public officials, family and friends at Sunday's dedication.
Gerardi was a Vietnam War veteran who was active at the Northport Veterans Administration Hospital and in veterans’ concerns. He worked in the construction trades, in real estate and as a restaurant owner; most of his working life was spent as a member of the Cement Masons.
