As Jason put it a few days ago, the Yankees need starting pitching. Other than CC Sabathia, Masahiro Tanaka, and Michael Pineda, there is not a single starting pitcher you could comfortably slot into the starting rotation. There are a litany of maybes: Luis Severino, Luis Cessa, Adam Warren, Chad Green, and Bryan Mitchell will likely get a shot at the final two spots, but there’s a good chance all of them will be better in the bullpen.
This is a 2017 issue, and there may be some short-term solutions.
