Except all the evidence suggests the guy is simply done as a major league-caliber pitcher. Velocity is gone and all of his pitches are getting hit hard. Only thing he had to really fall-back on was his control, but even that has totally left him to start the season. Like Jake Arrieta and Dallas Keuchel before him, it happens.
Main thing is he really wouldn't be an improvement over the options we currently have, with Houser set to return from the IL.
