Stephen Thomas Bilko (November 13, 1928 – March 7, 1978) was an American professional baseball player known for his home run hitting as a minor leaguer during the 1950s.

Bilko threw and batted right-handed; he was listed as 6 ft 1 in (1.85 m) tall, and 230 lb (100 kg), and was nicknamed "Stout Steve" during his career because of his ample girth.

[1] Bilko was born in Nanticoke, Pennsylvania, in coal mining country, and made his debut with the Allentown Cardinals in 1945 at the age of 16 during the final year of World War II.

His Triple Crown year came for a pennant-winning Angels' team that won 107 games, and was sandwiched in between seasons in which Bilko belted 37 (1955) and 56 (1957) long balls.

However, Bilko got into only 47 games with the Wrigleys (only 22 of them at first base) before he was sent at season's end to the PCL Angels, the Cubs' top minor league affiliate, where he would become a legend.
