The Yankees went 13-16 during the month of May partly because their pitching staff had a 4.38 ERA (4.07 FIP) overall, which was quite a bit worse than the AL average (3.80 ERA and 3.97 FIP). The rotation had a 4.36 ERA (4.22 FIP) in May while the bullpen had a 4.43 ERA (3.78 FIP). I’m not even going to calculate the non-Dellin Betances/Andrew Miller portion of the bullpen because yeesh.
Anyway, the Yankees are getting some pitching help this week when Masahiro Tanaka returns from his wrist/forearm injury on Wednesday.
