I think its reasonable to operate under the assumption that Santander and Garcia are done for the season, at least with the trade deadline in mind.
That would push my priorities to
1) Shutdown RP ( Clase, Duran, Bednar, Halsey, Jax,)
2) Everyday bat ( Ward, Duran, Mullens, Suarez, Kwan)
3) Legit SP upgrade ( Degrom, Cabrera, Gray, Eovaldi, Alcantara)
4) Middle RP
5) Rental SP ( Gallen, Lugo, Morton,Kelly)
6) Platoon RHH ( Bader, Laureano, Grichuk, Refsnyder)
What im not interested in is a SP with term that is just kinda samey to our SP, the cost will be huge and i'd rather just trade for a rental, and sign a FA than pay the trade cost of a mediocre arm like Keller or Severino, just because they have term. If it's a legit upgrade, sure, great, and i would have any prospect in play, but these injuries should concern them.
