29% of all perfect games in MLB history have happened in the last 3 seasons. It should be higher if Armando Galarraga didn't get robbed by umpire Jim Joyce. So what does it all mean? I guess steroids do actually work for hitters.
Congratulations go out to Felix Hernandez on the perfect game. He should thank his defense. They made a lot of clutch plays to keep the perfecto intact. 27 up. 27 down. Amazing.
