I don't see Malloy or Jung making the Tigers' roster unless there are a bunch of injuries.
Malloy's value is pretty low because of his poor defense. He's a DH unless you want to try him at 1B, but he hasn't hit well enough yet in the majors to show he can be a regular 1B or DH.
Jung's only position is 3B (he can play 2B but he's not good there) and he's another Tigers' lefty hitter and he can't hit lefties. We have enough of those.
Malloy and Jung could be throw-ins in a multi-player deal with someone, but they really don't have much value anymore.
The time to trade them would have been 2 years ago.
(By the way, I still think Malloy could turn out to be a decent hitter for someone, especially in a hitter-friendly ballpark, but he has little future with the Tigers given how Hinch constructs his roster and that Torkelson and Carpenter are in front of him).
