Nikolaos Mastoridis

Nikolais Mastoridis was born in Greece but in late January 1921 sailed from Piraeus aboard the SS Themistokles and made permanent residence in the United States. He settled initially near Youngstown, Ohio, where he was an Ohio State boxing champ and later won a New York Golden Gloves title, by then living near East Rockaway, Long Island.

Mastoridis turned professional in 1934, boxing under the name Nick Masters. He fought until 1937, finishing with a career record of 16 wins, 10 losses, and 3 draws. Masters won 11 of his first 12 bouts, but then lost 9 of his final 15 career bouts. He always fought in New York State, mostly around New York City, and he retired after being knocked out in June 1937 by George Brothers.
