[Phillips] I recently spoke to Yankees starter Cam Schlittler about his offseason plans, which include expanding his arsenal. We also chatted about returning home to Boston a bit of a villain, limiting his trash talk on social media and more:

He has been living with two of his Northeastern teammates, Yankees farmhand Thomas Balboni Jr. and Padres prospect Eric Yost, and training at their alma mater. Throwing began a few weeks ago, and Schlittler, who primarily relied on his 98-mph four-seam fastball (55% usage), cutter (21%) and curveball (15%) last season, plans to incorporate a changeup or a splitter this winter.

Schlittler, who also has a sinker and slider, said he was still deciding on which pitch to develop. However, Yankees pitching coach Matt Blake told The News that the changeup is more likely after Schlittler struggled with the pronation of his wrist while tinkering with a splitter last spring.

“We’re trying to get him something that he can get below the barrel but can command,” Blake said, adding that he wants Schlittler to refine what he already has, though a changeup would help him against lefties. “How do you avoid the foul ball war? How do you get some weak contact at times?”
