Some of those players are already in Boston however.
Catcher is a position where offense is often treated as a bonus, since good all-around catchers are tough to come by and defense is really the priority. Ive thrown out Sean Murphy as a target, since he had some pop and is a very good catcher relegated to backup duty. He’s currently on the IL right now. Atlanta needs help at SP and SS. While Story would at least represent a cost-savings, he doesn’t necessarily represent a solution at SS due to his own inability to stay healthy. Plus he is a RHH either way some pop, which is what Boston does need. (No way in hell do you trade Mayer for Murphy.)
The infield overall hasn’t produced. Story has been out after finally realizing he cannot play with a hernia. Mayer could be sent down once he returns, but Story isn’t much of a SS right now. Durbin isn’t going anywhere and has been hitting better after a dreadful start. But an INF with some pop would make sense if they demote Mayer.
LF/DH they have some internal options. Certainly Anthony fills one spot. Duran is still in Boston for the time being, and has shown over the last two seasons he is much better than what we’ve seen this year. But he is also a candidate to be moved. Triston Casas isn’t dead yet, and poses a dilemma. On one hand, he’s been very fragile and missed the bulk of the last 2.5 seasons. On the other, he has shown he can hit. Ultimately he will be a tough decision come non-tender time.
Barring an upgrade at catcher - maybe a Mayer-Dalton Rushing trade - maybe we only see a new DH and one INF? I don’t see the Sox adding so many new starting bats. Thats a massive turnover…
