Meadows because of his elite defense is going to get all the chances he needs until Clark is ready. You can use Vierling, Perez, Baez and others there if need be but I’d be very surprised if that was a position they’d make a move at.
Position player wise you can make an argument for a 3rd baseman although with Torres returning room is tight so it has to be a high level player and then it comes down to will they pay for that. Maybe a right handed corner outfielder as I think that could be cheaper and help balance out the lineup.
