None of those are on the MLB roster which I thought was clear, but I guess not.
And, Larnach and Wallner are sitting in AAA while Gallo produces the 26th worst fWAR among LFers.....so, they must not love them much. Not to mention 3 bad years from Kepler.
Celestino might or might not be ready next year, but again, we have no idea if he can hit MLB pitching.
Gordon is, at best, a backup.
