Assuming Crochet opens the year in the minors, who is in the pen as of now? For 8 spots, you have Hendriks, Bummer (L), Marshall, Heuer, Foster, Fry (L) as the likely locks, probably a long-reliever/spot starter (not sure who would serve this role as of now as I also think Lopez opens the year in the minor as a middle-reliever), and then one more spot that as of now I guess could go to Ruiz or Cordero. I assume they will upgrade that spot or add a long-reliever.
Edit: just saw the new tweet, Not really news here as every team signs guys to minor league deals for bullpen depth.
