We have no idea of where at or what this roster will look like in July of next season to say today he is blocked.
If this kid at 21/22 ends up putting up solid numbers in AA and AAA, and looks like he ready for mlb action, you find a spot for him.
I mean, outside of Amaya, Hoerner, Swanson, and Bellinger if he resign , no position player on this current roster is untouchable.
