Although Adam Warren’s 2016 numbers are pretty ugly– 4.68 ERA and 5.12 FIP in 68.1 IP– he seemed to return to his old self after coming back to the Yankees in the Aroldis Chapman trade. One of the first people who Warren sought out upon returning to the Bronx was his long-time pitching coach Larry Rothschild, who already had a pretty good idea what had gone wrong with his former player in Chicago.
When asked what he was working on with Rothschild, Warren told beat reporter Chad Jennings, formerly of the Journal News:
Just working on a couple of mechanical things, getting the slider back — the depth back to the slider.
