The Allentown Red Sox (A-Sox) were a minor league baseball team, affiliated with the Boston Red Sox and based in Allentown, Pennsylvania, that played from 1958 through 1960 in the Eastern League. At that time, the Eastern League was officially Class A, but, prior to the minor-league classification realignment that took place in 1963, that level was almost equivalent to Double-A. History From 1939 through 1952, Allentown had hosted a Class B Interstate League franchise, the Cardinals—also the Dukes, FleetWings and Wings—and for much of that period, it was an affiliate of the namesake St. Louis Cardinals. When the Interstate loop folded, the Cardinals returned to Allentown in 1954 as a member of the Eastern League for three seasons, through 1956. The Allentown Red Sox franchise dates to 1933 as the Reading Phillies. It became a farm team for the Red Sox in 1938 as the Hazelton (PA) Red Sox. In 1957, the Red Sox purchased the former Detroit Tigers Eastern League team, the Syracuse Chiefs, and moved the club to Allentown mid-season, being operated as an unaffiliated team for the balance of the season. The Red Sox ended their affiliation with their Eastern League team in Albany, New York after the season and reassigned it to Allentown for the 1958 season. Owned by Joe Buzas, the team played for three seasons at Max Hess Stadium (formerly Breadon Field), owned by Max Hess, Jr., owner of the Allentown Hess Brothers department store. Former Allentown player Tracy Stallard is remembered as the pitcher who served up Roger Maris' 61st home run in 1961 while playing for Boston. Another player who appeared at the stadium was Curt Simmons, a native of Egypt, Pennsylvania, who pitched at Max Hess Stadium in a rehab assignment for the Asheville (NC) Tourists, a farm team of the Philadelphia Phillies. The presence of Curt Simmons filled up the stands. For the 1960 season, Bob Heffner, who graduated from Allentown High School as a two-sport letterman in 1957 played for the A-Sox. He had the best pitching record on the club at 16-9. Heffner later played in the majors for the Red Sox, Cleveland Indians and California Angels in 1968. The A-Sox's best season was 1960. On September 3, 1960, the Red Sox kept its Eastern League playoff hopes alive with a 7-6, 3-2 sweep of Williamsport at Hess Stadium, the second of four straight doubleheaders the A-Sox
