If lefty power is what they are looking for, probably the closest in oWAR would be Cano. There are a lot of obstacles to acquiring him. One being a NTC. He may not wave it if he wants to play defense which his defense when compared to the incumbent second baseman isn't as good. Then there is the matter of his $24 million/yr owed through age 40 (2023 season) and the acquisition cost. Never mind how interested Seattle would be in moving him.There are some assumptions in a few posts that puzzle me. One is that Moncada will learn how to hit breaking balls. (Wasn't that an expectation with Castillo?). The other is that pitchers have found the way to get Leon out and that he will not be able to adjust. (In my opinion, Leon was exhausted by the end of the year. I think he may be able to adjust, and his work throwing guys out has a lot of value.) Also, I know that late-season Travis Shaw was a hyuuuuge disappointment, but some of the posts underrate his value to the team after the Panda incapacity. Another suggestion I disagree with is trading BROCKHOLT. I think Farrell loves him, and unless they get something very shiny, he will stay with the Sox.
p.s. Is there no interest in making up for the loss of a left-handed power hitter? Encarnacion is good, but he doesn't replace Ortiz, for that reason.
I'm not supporting this idea, simply bringing it to the table for discussion for the greater minds of SoSH.
