Sczesny, a native of Flushing, New York, spent 55 years in baseball, all of them in the Red Sox organization.
Sczesny graduated from Bishop Loughlin Memorial High School in Brooklyn, and attended St. John's University.
He signed with the Red Sox in 1954 and played in their farm system through 1959, except for the 1957 campaign, which he missed while performing military service.
However, he handled many future Major Leaguers as a skipper of Class A farm clubs in the Red Sox chain, until 1970, his final season in uniform, when he served as the first manager in the history of the Pawtucket Red Sox, then Boston's Double-A Eastern League affiliate.
Sczesny scouted and signed future Red Sox stars Mo Vaughn, Bob Stanley and John Valentin, among others.
