I don't understand the talk of resigning Maybin. The Astros have Marwin, Marisnick, and Fisher. Please don't bury Fisher to bring Maybin back.
As I see it, the Astros need to make a decision about whether they get another hitter for DH (to replaced Beltran) or whether they go in-house with White, Davis, Moran, or Reed.
Astros probably need some more relievers, although I'm not ready to throw Giles out (as some people are).
Is Fiers a non-tender? If not, what do you do with him. The 5-man rotation is pretty much set at Verlander, Keuchel, McCullers, Morton, McHugh. And there are plenty of other options if/when the injuries happen: Peacock, Musgrove, Martes, Paulino, Rogers.
