The Red Sox acquired veteran first baseman Eric Hosmer on Tuesday in a deal with the Padres.
Boston sent prospect Jay Groome to San Diego for Hosmer, infielder Max Ferguson (SD's #11 prospect), outfielder Corey Rosier (#26) and cash.
Hosmer, 32, is owed $39 million from 2023-25. It's not yet known what portion of that amount will be paid by the Red Sox. MLB.com's Ian Browne offers a "reasonable" scenario in which Hosmer and Triston Casas, both left-handed hitting first basemen, share the 1B/DH slots since J.D. Martinez is a free agent at the end of this season.
