Stewart's game log
He's faced the Twins 3 times, got manhandled once and did very well twice. He's pitched well against DET, KC and BAL. Maybe that was his best game, but hell that's some HOF pitcher's best games too. And no, I'm NOT saying Zach Stewart is going the the HOF. Just stating that the post woy cited leaves a lot of room for performance variation. If that is his peak and he pitches say 85% as well as that over the course of his career, then that's a pretty good career.
To keep it somewhat in the Reds family, I think Stewart has more upside than Dustin Mosely
