On May 11, 1972, future Hall of Famer Willie Mets was traded to the Mets for pitcher Charlie Williams and $50,000. At the time, Mays was 41 years old and in his 21st big-league season, and he had little left in the tank, hitting just .238 with 14 home runs in 135 games with the Mets before retiring. Williams, the player the Giants acquired in exchange for their legend, would pitch to a career 3.97 ERA for San Francisco, primarily as a reliever.
