Howard Johnson breaks a 53 year-old National League record when he strokes his 36th home run as a switch hitter in the Mets’ 7-1 victory over Chicago at Wrigley Field. The New York third baseman’s historic homer, the team’s franchise-high seventh grand slam of the season, surpasses the mark established by Cardinals’ first baseman Ripper Collins in 1934 but is far less than the major league record of 54 set in 1961 by Yankees slugger Mickey Mantle.
