The 2027 infield outlook is definitely a bit murkier than I see the 2028 infield.
First: If you asked me at the start of the off season I would have guessed Vaughn would be playing elsewhere in 2027. He still might be, but i'm finding hard to believe we would trade Vaughn and Contreras in the same off season. I do expect us to trade contreras, so if Vaughn is worth tendering a contract to, he could be our primary first baseman in 2027. Maybe Black gets a crack at the Bauers role, he'll be out of options after all.
Second: Turang. not much discussion needed for 2027.
SS: with the Pratt extension, I expect he'll be the primary SS in 2027. Not sure what to make of the Ortiz situation, if he rebounds to a league average bat it's a tougher decision.
Third: I think at some point, even if it isn't opening day, Made will be the primary third baseman in 2027. I hope we're able to sign him to an extension and the Emerson deal is a pretty reasonable comp.
2028 I think the picture is much clearer. I expect Turang, Pratt and Made to entrenched as starters and I think Fischer winds up slotting in at first base.
