There are now twenty perfect games pitched in the history of Major League Baseball, and Roy Halladay has the more recent one.
Dallas Braden had the last perfect game, less than a month ago. ESPN reports that:
• Oakland's Dallas Braden threw a perfect game on May 9. The only other season with two perfect games was 1880: Lee Richmond (June 12) and John Montgomery Ward (June 17).
• Of the 20 perfect games thrown in baseball history, three have come in the last two seasons.
• The Phillies are the fifth team to have had two perfect games in their history. Jim Bunning threw Philadelphia's other one on June 21, 1964 vs. the Mets.
