On June 21, 1964, Jim Bunning of the Philadelphia Phillies pitched the seventh perfect game in Major League Baseball history, defeating the New York Mets 6–0 in the first game of a doubleheader at Shea Stadium.

[1] Needing only 90 pitches to complete his masterpiece, Bunning struck out 10 batters, including six of the last nine he faced.

Bunning, who no-hit the Boston Red Sox while with the Detroit Tigers in 1958, joined Cy Young as the only pitchers to throw no-hitters in both the National and American Leagues; he has since been joined by Nolan Ryan, Hideo Nomo and Randy Johnson.

The perfect game also made Bunning the third pitcher, after Young and Addie Joss, to throw a perfect game and an additional no-hitter; Sandy Koufax, Johnson, Mark Buehrle and Roy Halladay have since joined him.

Bunning had abided by the tradition during a near-no hitter a few weeks before, determining afterwards that keeping quiet didn't help.
