Last week, the Yankees added a major relief pitcher in Aroldis Chapman, signing him to a record breaking five-year, $86 million contract. Chapman joins Dellin Betances and Tyler Clippard to form a strong late-inning trio that should help the Yankees win most games where they take a lead into the seventh inning. Given the Yankees’ weak rotation, however, their middle relief will most likely be called upon to pitch a lot of innings. With only a handful of unproven middle relievers currently on the roster, the Yankees may look to free agency for some more established pitchers.
