Carbone also won last year's installment of the annual contest at Rocco's Pizzeria. The event raises money for the child-welfare organization MercyFirst.
Five pizza eaters faced off Sunday. Contest co-founder and Rocco's co-owner Joseph Loccisano said runner-up William Millender powered through about 12 1/4 slices.
Loccisano said the contest brought in about $4,000 for MercyFirst. It runs group homes and other services for about 4,000 children, teenagers and families in New York City and on Long Island.
