Amazing Stats in Baseball (and Longevity)

My Twitter feed has been filled recently with weird stats about 49 year-old pitcher Jaime Moyer. Moyer last night became the oldest pitcher to win a game in Major League history. The Twitter pieces have ranged from the age disparity between him and the opposing pitcher, to the disparity between the speed of his fastball and that of the average pitcher. Anyway, most of the stats have been interesting, but this one from Buster Olney kind of blew my mind...

Elias: Jamie Moyer has pitched to eight percent of all hitters in major league history. - @Buster_ESPN

Just a reminder: major league baseball is over 100 years old. Crazy.
