Cruz is unlikely to return to the Rangers next year, so Rios would be a decent long-term replacement. They will part with either Odor, Sardinas, or Jackson I'm sure.
1) Get Garcia in the lineup and let him make adjustments at the major league level. He has nothing to prove at AAA.

He can't play anymore. He's a DH who can't hit. All of the scouts around MLB are aware of this. If someone would have wanted him around as even a bat off the bench, we would have given him away at the deadline. Obviously he's still here.
