Saturnino Escalera Cuadrado (December 1, 1929 – July 3, 2021) was a Puerto Rican former professional baseball player and scout whose playing career extended for 14 seasons (1949–1962).

Born in Santurce, Escalera started his baseball career at a very young age, often playing with his brothers and neighbors from the Loiza Street in his hometown.

In 1946 at the Amateur Baseball World Series held in the Latin American Republic of Colombia, Escalera was named best first baseman and most valuable player (MVP) of the tournament.

The hitter was the St. Louis Cardinals' Baseball Hall of Famer Stan Musial, who would set the NL record for career hits before his 1963 retirement.

Facing right-handed pitcher Art Fowler, Musial struck out to end the inning, denying Escalera a fielding chance.
