Congratulations to Philadelphia Phillies pitcher Roy Halladay, who, yesterday, became the 20th player in Major League Baseball history to pitch a perfect game. Earlier this month, Dallas Braden became the 19th such pitcher. Thirteen years elapsed between perfect games by Catfish Hunter and Len Barker. Now we have two perfect games in one month. Does this cheapen the feat? I'm inclined to think that it does.
