Assuming Soria is going to be a rental, which I'd say at least 75% chance he will be, in this case no, trading Medeiros does indeed free up a 40 spot in the offseason. I think this trade might the ticket onto next year's roster for Quintin Torres-Costa, whereas otherwise he likely would not have made it. So if it helps, it may essentially be adding Soria now and Torres-Costa later for Medeiros + Perez might be the way they are looking at it. Not saying it's right or wrong, I really have a hard time seeing Medeiros go. Just spitballing on what their thought process might be.
