On October 1, 1961, Willie Mays hits his 40th home run when he goes deep off Lew Burdette in the Giants’ 8-2 victory over Milwaukee in the opener of a twin bill at County Stadium. The ‘Say Hey Kid’ is the eighth player to reach the mark this season, a major league first, joining Roger Maris (61), Mickey Mantle (54), Harmon Killebrew (46), Orlando Cepeda (46), Jim Gentile (46), Rocky Colavito (45), and Norm Cash (41) in accomplishing the feat.
