The end of the roster math is starting to get interesting, as much as that can be true even for roster sickos. With the 40 man, it's currently full so Hosmer needs to replace someone. The recently signed Kay is an obvious target, but after that you have to at least squint. Other candidates could be Rucker, one of Mastrobuoni/McKinstry, after that you're having to part with upside(Estrada/Rodriguez) or recent MLB form(Sampson/Assad). Plus this isn't likely to be the last addition of the offseason, I'd expect there to be at least one more reliever brought in, and in optimizing the 26 man roster you could probably stand to add an OF to the mix too. Several 40 man guys could be trade options for one of those(Madrigal, Sampson, maybe Velazquez), and strictly speaking you don't have to have another bat(the bench is already a roster spot heavy unless you're optioning Madrigal, Velazquez can be the reserve OF), but the path gets a little hazy from here.
