Al Jackson has a distinguished accomplishment in New York Mets history. He pitched for both the 1962 team and later appeared in nine games for the 1969 ball club. In those earlier years from 1962 through 1965, Jackson was one of the mainstays in the rotation, often suffering from a lack of support around him both on offense and in the bullpen.
The word “unlucky” isn’t quite accurate for Jackson. However, when comparing his 4.26 ERA to the 3.51 FIP he had as a member of the Mets, we can raise an eyebrow at the results.
