This FO knows how to get rid of Morales if they really want to, but some team (AL only given his lack of every baseball skill needed to play elsewhere) would have to be desperate. I doubt we see either Morales or Martin gone before the end of 2019. Maybe Morales has somewhat of a bounceback second half 2018/1st half 2019 and maybe some AL club will get desperate, but I doubt it. Hell, they may even bite the bullet and DFA him if he hovers around replacement/sub-replacement level..... but again, I doubt it.
Martin is moveable next year at the deadline if he's even half competent with the bat next season simply due to his defensive reputation and vetrin presents.
