Digging into these players more, I think they are nice pieces but probably all guys who will live on the tail end of the 25 man roster.
Bloss in MLB has been mostly fastball (44%) and slider (34%). By Stuff+ those pitches are a 99 and 115. That is decent, but neither is an obvious plus pitch or a difference maker pitch. The fastball velo is not plus. Yes he was rushed to the big leagues and could use more development but he's also a physically mature 23 year old. This is an SP5, SP6 type without more development and the ceiling is probably only an SP4 and that is if he can improve (add quality third pitch, bump up the velo, add other fastballs, etc.)
Loperfido is a bit old at 25 and his K rate ballooned in AAA starting in 2023, which continued into 2024. The hit tool issues are real. His probable outcome is a platoon LF/RF/1B. He may be able to add some value on the bases and on defense which helps but offensively this might just be a Jake Bauers archetype.
Wagner has no power or speed and the defense is below average per scouts. So unless the hit tool is nearly Luis Arraez level, it's not an MLB profile.
