The Red Sox could move forward with Arenado at third, Devers as their DH and Casas at first base for the three years remaining on Arenado’s contract without disrupting anything related to the development of Campbell, Marcelo Mayer or Roman Anthony. That’s no small thing in the attempt to get more functional.

The Boston Red Sox still need another right-handed bat in the lineup, and could potentially fill that void with a trade for St. Louis Cardinals third baseman Nolan Arenado.
