Fangraphs’ Carson Cistulli, wrote back in January that the Yankees’ bullpen had the potential for a “possibly historic” season according to Dan Szymborski’s ZiPS projections. Cistulli wrote:
“More notable, however — indeed, possibly historic — is the club’s bullpen. Aroldis Chapman (52.1, 55 ERA-, 1.8 zWAR) is the nominal closer, but any of the pitchers featured in the depth-chart image below is capable of handling high-leverage innings. Dellin Betances (60.2, 67, 1.5), Chad Green (73.0, 67, 1.6), and David Robertson (59.2, 62, 1.7) are all forecast to record ERAs at least 30% better than league average.
