Exactly, there will be about 20+ games left in the season when they call players up in September. Be cool if they still have a shot at catching the Braves then but I doubt it.
They have kids that are ready or near ready to play, so whether it Triantos Shaw or even Vazquez it more about getting them AB over the final weeks then position they play.
If Paredes is hurting and he's still not hitting then there's zero reasons to keep him in the lineup everyday.
