One thing has become clear in recent weeks: the Yankees need bullpen help. Aroldis Chapman and Dellin Betances are arguably the best closer/setup man tandem in baseball, though there are other innings that need to be pitched, and those other innings have cost the Yankees too many games of late. The middle relief is a major weakness.
The Yankees could try to address the middle relief from within, something I suspect they’ll try at some point, though going outside the organization for help is always an option too. Trading for bullpen help can be tricky though.
