Q: 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 Felix Hernandez 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.
Can we conclude that has there ever been a perfect game in the world series?
A: yes
