When did Jim Bunning of the Philadelphia Phillies pitch his perfect game?
He pitched a perfect game on June 21, 1964, which was Father’s Day that year. This was the first game of a doubleheader against the New York Mets at Shea Stadium. It was the first perfect game during the regular season in the major leagues in forty-two years, and the first ever in the National League.
