FILE - In this Aug. 22, 1965, file photo, San Francisco Giants pitcher Juan Marichal (27) swings a bat at Los Angeles Dodgers catcher John Roseboro as Dodgers pitcher Sandy Koufax, rear right, tries to break it up in the third inning at Candlestick Park in San Francisco. Violence is part of the game in many sports.
