Signing Bregman was a huge win for the Red Sox, as the star third baseman agreed to a three-year, $120 million deal in February. But that deal included an opt-out after each of the first two seasons, and after making his third American League All-Star team this year, Bregman seems likely to re-enter free agency.

This acquisition would give the Sox an amazing hitting upgrade, and could replace Bregman if he walks in free agency.
