In a vacuum, bringing back J.D. Martinez is a no-brainer for the Dodgers. Los Angeles signed Martinez to a one-year deal last winter to essentially replace Justin Turner and the results were fantastic.
Martinez had a better season at the plate than Turner ever really had with the Dodgers. In only 113 games, Martinez hit .271 with 33 home runs and 103 RBI. If Martinez had stayed healthy and played 150 games, he would have finished with 43 home runs and 136 RBI, based on his projections.
It may seem like a no-brainer but the situation is complex and could cause Martinez to leave the Dodgers in free agency. First, after a season like this, there are undoubtedly going to be more teams interested in Martinez in free agency. That alone will raise his price and could cause the Dodgers to back off.
There's also the Max Muncy element of this. Muncy is one of the worst fielders in the league at third base but he has to play there with Martinez as the DH. Are the Dodgers going to commit to an entire season of Muncy at third again? Or will the team transition Muncy into being a full-time DH and play someone else at third?
And then there's the whole Shohei Ohtani pursuit that would automatically boot Martinez off the roster. Complicated stuff.
