Astros: 3 ways for Zack Greinke to rejoin the 40-man roster

For Zack Greinke’s return, the Astros could move a pitcher to the 60-day IL.

Rafael Montero or Pedro Baez to the 60-day

As discussed before, the ball club has a few possible 60-day IL patients in their pitching room. A few of them will remain on the 40-man roster due to service time limitations, like Forrest Whitley, who just started throwing again, and Jairo Solis.

Now, Montero and Baez are in throwing programs, but how impactful would they be to a postseason roster? Montero proved a lot of us wrong, as he looked to be more than a throw in, but Baez can’t touch anywhere near what his velocity once was. Either pitcher’s transfer would have them out for the remainder of the season and possibly postseason, while they would both require rehab assignments to return.
