Overall conclusion: Talk to Soto and see if he'll commit to Boston, then see what the terms will be
It's no secret that Soto is most likely going to be moved this off-season, it's just a matter of the Padres finding the best trade partner. Some outlets are saying the New York Yankees, some are saying the Los Angeles Dodgers, but I'm saying the Red Sox.
The best course of action from here is to try talking to Soto and his agent and seeing if he just wants a change of scenery or a place to call home.
If it's the latter, it's time call up San Diego's front office and see what they want for him. If it's the former, Boston should be inclined to give them what they want considering he will likley be a rental for the 2024 season.
