Jim Bunning of the Phillies pitched the only perfect game in the 80-year history of the National League. That he won this game against the second-rate Mets fazes Bunning not a bit. Other pitchers pitch against the Mets all season--""and how many have retired 27 in a row?"" Bunning also had a no-hitter against the Red Sox in 1958. Bunning here unabashedly relates his life story-- of his Kentucky boyhood, high school and college games, and days in the minor leagues. During his first major leagues season with the Detroit Tigers, he won 20, lost five. He has interlarded separate chapters about building the future and off-the -field considerations, and about all-star games (which he thinks are merely spectacles). And there's a special batch of pitching observations. After reading them the reader feels he could go out and shutout the Yankees. Bunning is married and has seven children. He tells history in a humorless, no-nonsense way, keeping mainly to how the games went; there's no jazz about locker room hijinks, club spirit and after-hours frolics.
