Aside from the vaunted late inning triumvirate of Aroldis Chapman, Andrew Miller, and Dellin Betances, the Yankees bullpen has actually been a mess this season. No member of the Scranton Shuttle has found consistent success at the big league level this year.
The club has used their remaining four bullpen spots as a revolving door for Quad-A journeymen and fringe prospects, hoping to find someone to help bridge the gap between their starters and the big arms at the end of the game. The team declined to bring in any veteran bullpen depth this winter, and that cost-cutting move has hurt them.
