One area of the SF Giants roster that will be tough to make additions
The Giants have outlined a long-term plan with Rafael Devers and Bryce Eldridge. The plan is for them to split time at first base and DH.
Devers is signed through the 2033 season. He originally came up as a third baseman, but moved off of that position this year.
