In 1953, Major League Baseball saw notable changes:
Relocation of a Franchise: The Boston Braves moved to Milwaukee, marking the first MLB franchise relocation in 50 years. They played their home games at the new County Stadium in Milwaukee. This move was significant as it set a precedent for future franchise relocations in the league.
Televised Games: 1953 was also the first regular season featuring the televised "Major League Baseball Game of the Week," which expanded the reach of the sport to a broader television audience.
Rule Modification: An equipment rule change was announced, where players were to remove their gloves from the field when batting, and no equipment was to show on the field at any time. This rule was to take full effect in 1954 (source).
These changes reflect a period of transition and modernization in MLB during the early 1950s.
