If you look at Jose A Ferrer’s season numbers, you will not be impressed. He has a 5.59 ERA in 28 appearances. However, when you look under the hood and examine his recent performances, it is easy to see that there is more than what meets the eye.
Despite Ferrer’s sky high ERA, the underlying metrics suggest he has been very unlucky. His FIP sits at 3.04 and his xERA is 3.16. A lot of this comes down to bad batted ball luck. As a sinker baller who relies heavily on ground balls, Ferrer will always be at the mercy of the BABIP gods.
