Thomas Boswell today in The Washington Post:
Baseball umpire Jim Joyce made a hideously incorrect ruling Wednesday night that cost Detroit Tigers pitcher Armando Galarraga one of the rarest achievements in the sport: a perfect game. But 15 hours later, when Galarraga made his way to home plate before Thursday afternoon’s game to present his team’s lineup card to Joyce, the umpire’s reception was just as clear-cut. The fans in Detroit cheered, and baseball and sport had one of its most inspiring and least expected moments. …
Fans of the recession-scalded Motor City brought themselves to cheer for a man who admitted his mistake, which had denied one of their own a perfect game, a feat accomplished just 20 times since 1858. And, everywhere, observers shook their heads that a thing that was so sad and screwed up late Wednesday night could, simply by good will and compassion, be turned into something sparklingly fresh, unexpectedly strong and best-of-baseball by Thursday afternoon.
The list in this link indicates a maximum gap of 34 years between perfect games, from 1922 and ending in Don Larsen’s feat in the 1956 World Series. And yet, there have been three others in just the past 12 months.

I suspect that in this generation, the one from 2010 that will stand out the most (other than for fans in Oakland and Philadelphia) is this would-have-been 21st perfect game.
