We'll need to clear 2 spots when we activate Pineda and Peralta. 2 more to trim down to the 26 man roster. Another one for Chafin. And then another when Greene comes back. That's 6 guys off the current roster? Depending on available options, I think Vest, Foley, Barnes will all be gone. Position players? Reyes? Maybe not carry 3 catchers? Hopefully Grossman isn't hurt too bad. Groins can be hard to heal in chilly weather. Better off being safe and wait until it's totally healed before playing him.
