My dad and I were at this game..
Giants pitcher Juan Marichal had hit two Dodgers batters with brushback throws. Dodgers pitcher Sandy Koufax disliked retaliation and only threw a very high pitch over the head of Willie Mays. When Marichal came up to bat later, Koufax apparently had no interest in retaliation directly against Marichal, but Marichal felt that Dodgers catcher Johnny Roseboro was interested, as he claimed Roseboro was returning Koufax's pitches dangerously close to Marichal's head and had clipped his ear with one throw after dropping the ball on the ground. As Marichal and Roseboro began to argue, Marichal (#27) hit the Dodgers catcher on the head with his bat. A bench-clearing brawl ensued. Giants infielder Tito Fuentes (#26) also threatened to wield a bat, but did not use it. The fight was broken up by peacemakers Willie Mays of the Giants and Koufax of the Dodgers. Mays helped the badly bleeding (but not severely injured) Roseboro off the San Francisco field. Roseboro and Marichal eventually became close friends up until Roseboro's death in 2002. Marichal spoke at his funeral. Actor and performance artist Roger Guenver Smith performed his one-man show on the incident, "Juan and John," at the Public Theater in Manhattan in December 2009. Roseboro's daughter, Morgan Fouch Roseboro, attended the debut
Way cool tho that they became friends...
