Willie Howard Mays Jr., nicknamed "the Say Hey Kid", is an American former center fielder in Major League Baseball (MLB). Regarded as one of the greatest players ever, Mays ranks second behind only Babe Ruth on most all-time lists, including those of The Sporting News and ESPN. Mays played in the National League (NL) between 1951 and 1973 for the New York / San Francisco Giants and New York Mets.

The New York Giants were a Major League Baseball team in the National League that began play in the 1883 season as the New York Gothams and became known as the Giants in 1885. They continued as the New York Giants until the team moved to San Francisco, California after the 1957 season, where the team continues its history as the San Francisco Giants. The team moved west at the same time as its longtime rival, the Brooklyn Dodgers, also in the National League, moved to Los Angeles in southern California as the Los Angeles Dodgers, continuing the National League, same-state rivalry.
