Casas is a pretty valuable trade chip. I can’t think of too many players we have that would interest Boston for him. They are a large market team that will either want to improve the 2025 roster or add absolutely premium prospects.
Garrett Mitchell, Jesus Made, Jacob Misiorowski these are some names that come to mind.
Freddy Peralta is a good guess too but I don’t see how it works for them because they don’t need a SP that much. Contreras, Ortiz, Turang would interest them but there is no trade there that works for us.
