The Yankees starting pitching rotation, much like the team itself, is in a state of flux for the 2017 season. With the exception of Masahiro Tanaka and (hopefully) Sabathia, no one knows what the team is going to get from guys like Michael Pineda, Luis Cessa, and Luis Severino.
Brian Cashman has said over and over again that he does not anticipate signing any of the remaining and watered down free agent pitchers who are still looking for a job. Cashman left open only a sliver of a chance that another starter would join the team via a trade.
