2018 will be Tanaka’s fifth MLB season. Tanaka has been the Opening Day starter for the Yankees for the past three seasons. This season he will be slotted behind Severino as the teams number two, or in my opinion, 1a. 2017 was Tanaka’s worst season statistically, posing a bloated ERA of 4.74. Tanaka never really seemed to find his groove in 2017, but the Yankees believe he’ll bounce back this year.
