One Red Sox catcher, Connor Wong, slashed .190/.262/.238 for a .500 OPS (42 OPS+) and -0.6 bWAR last season. His counterpart, Carlos Narváez, started the year hot but regressed for a season slash of .241/.306/.419, a .726 OPS (100 OPS+), and a 2.6 bWAR.

So, if the Sox want a fresh first baseman who can also catch, if they are not willing to risk it with Casas, and if St. Louis thinks Casas can regain his 2023 form, this trade could appeal to both sides. It would be a massive help for the Red Sox. 

Another option for Boston is to sign a free agent first baseman. Pete Alonso and Josh Naylor are off the board, but Ryan O’Hearn is still available. Cody Bellinger can also play first base.

If the Red Sox choose to go this route, they could option Casas to the minors, look for a trade partner, or, if it came to it, they could designate him for assignment. Another team would almost surely claim him off waivers.

If Breslow and Co. Think He Can

Casas could surprise Red Sox nation. He could pull a Trevor Story.

Story had not played a full season with Boston until 2025 due to injuries, but he managed to put up a 3.8 bWAR and slashed .263/.308/.433 for a .741 OPS (104 OPS+) this past year.
