Seven years ago, Adam Greenberg made his major league debut, and this happened. At bat one, pitch one, thud. Greenberg left the field with an On Base Percentage of 1.000, and since then it has not had the chance to go down. He went back to the minors the next season and followed that up with stints in the Dodgers, Royals and Angels organizations. After 2008 though, he was out of baseball.
