Alex Rodriguez is having an excellent 2015 season as the primary DH of the New York Yankees. This is somewhat unexpected given that he is a soon-to-be 40-year old coming off serious injury and lots of missed baseball. It typically doesn’t work this way. His resurrection warrants another inspection of his aggregate cost to the Yankees: both the contract they took on from the Rangers when they acquired him prior to the 2004 season and the 10 year/$275M (+incentives) contract that he signed prior to the 2008 season. The Yankees expected to underpay on the front-end and overpay on the back-end.
