We knew this day would come. Seeing Posada in a Florida uniform would have been too awkward. He spent 17 seasons in pinstripes, and that's how his career will end. It is awkward, however, to use the past tense for the first time when describing Posada's baseball career.
He was a five-time All-Star and Silver Slugger, and had two top-10 finishes in MVP voting -- the only year he slugged 30 homers (2003) and the only year he hit .300 (2007).
Andy Pettitte retired from baseball Feb. 4, 2011, nearly a year ago. As of tomorrow, only two of the Core Four will remain.
