Now we are hoping for injuries in order to have a trade partner. But that is what happened when Gary Sanchez went down. I have heard NYY is looking for catching depth. Heck, even Hicks would/should considered.
And then back to the first premise. They have to think Hicks, Liriano and/or Fiers is better than what they release/give up enough to make a difference. Not just slightly better. For teams already guaranteed a playoff spot (i.e. BOS, HOU), that player isn't for the rest of the season, it is for the playoffs. So it isn't guarding against current injuries, but for the post season. Additionally, will that player make a huge difference in the playoffs. Back end starter (Fiers) become bullpen arms. LOOGYs could never have to pitch in the playoffs. So the teams that would be interested in them are those struggling to make the playoffs in the first place.
