In 1955, Duke Snider lived at 178 Marine Avenue (in Brooklyn's Bay Ridge). His was the middle house in this picture.
Gil Hodges lived here, at 1120 32 Street. Two floors, 1400 square feet.
Sandy Amoros lived in Bed-Stuy, in this brownstone at 147 Bainbridge Street, most likely on just one of the three floors. His was the leftmost building.
And here is Alex Rodriguez's 2012 house in Miami, Florida. It's up for sale for $38,000,000,
which is what 19,681 square foot waterfront properties go for nowadays. A bargain, for all I know.
