<P> Over the 140 years of Major League Baseball history , and over 210,000 games played , there have been 23 official perfect games by the current definition . No pitcher has ever thrown more than one . The perfect game thrown by Don Larsen in game 5 of the 1956 World Series is the only postseason perfect game in major league history and one of only two postseason no - hitters . The first two major league perfect games , and the only two of the premodern era , were thrown in 1880 , five days apart . The most recent perfect game was thrown on August 15 , 2012 , by Félix Hernández of the Seattle Mariners . There were three perfect games in 2012 ; the only other year of the modern era in which as many as two were thrown was 2010 . By contrast , there have been spans of 23 and 33 consecutive seasons in which not a single perfect game was thrown . Though two perfect - game bids have gone into extra innings , no extra-inning game has ever been completed to perfection . </P>
