Baseball Hall of Fame pitcher,
Warren Spahn, the Boston Bees/Braves of the era did not have an extensive player development system. Class A was prior to a higher-level circuit, close to today's

Lincoln Chiefs of the Western League—inheritors of the Hartford team's nickname—and the
Jacksonville Braves of the
Sally League, whose star player in 1953 would be 19-year-old
Henry Aaron. ==Notable alumni==
