They have a very high chance of being in the playoffs. Even if they are an underdog against any other first-round opponent, I do not want to field a crippled roster for that series. So I am not trading expiring-contract assets like Gray. I am not trading Polanco, either - that would have been a defensible off-season move six months ago.
Players who do not fit the roster, I am fine with discarding in favor of a prospect already on hand - Gallo stands out, possibly Pagan. But depth in case of injury remains a concern so I don't want to weed out the roster very much.
Sure, get a reliever, preferably on an expiring contract so we don't spend much to get him.
This isn't our year, apparently. But a playoff invitation still is likely. So, small moves in either direction.
