According to Kenny Ken Ken.
Rumor is its JP Arencabia.
Can't say I'd be thrilled about dealing JPA so soon, but it doesn't look like he's going to hit enough to be a star player, and with aquiring Buck, Castro, and D'Arnard, the writing might be on the wall.
We don't know if its going to work, but hey at least its going to be interesting. Acquire as many high talent players as you can and see what happens.
