I actually expect Cincy to for Andrelton Simmons at shortstop this offseason, which not only kills their need for a SS, but also takes away the guy I would sign if the Sox dealt X.
Vazquez is a decent trade chip, and the Sox reportedly had talks with Tampa about him, although they might not have progressed as far as news interpretations suggest
Neander: "What do you want for Christian Vazquez?"
Bloom: "Your mother."
Technically, those are talks about Vazquez, but not really a strong indicator that he is available.
But let's say he is, because, well, what else have we got to talk about on here?
Per B-R, Vazquez hs one year $6.5mill remaining on his deal, with a very exercisable team option that turns it into a 2 year $13.25mill deal. There's a bonus for him exceeding 502 PA in 2020 and 2021, but I don't know how to view that since it did not have any known Pandemic Safety Clause.
His contract, coupled with his projected fWAR, has made BTV value Vazquez with a surplus trade value of $14.4 mill. Some starting pitchers falling within about $1mill of that on either side include: Framber Valdez (Astros), Domingo German (Yankees), Anthony Senzatela (Rockies), David Peterson (Mets), Kyle Freeland (Rockies), Kris Bubic (Royals), Logan Webb (Giants), and Sean Manaea (A's). The site lists Bubic's availablity as "Low", but everyone else as "Medium". so scratch Bubic. And German, because he is a Yankee.
The Astros do control their starting catcher (Martin Maldonado) for one more year, and I am going to assume would be happier with Maldonado and Valdez that they would be with Vazquez and without Valdez. The A's have Sean "Exit Velocity" Murphy, and will not want Vazquez. And the Giants have already started the service time clock for top prospect Joey Bart.
From the remaining teams, the Rockies finished dead last in catcher fWAR last season, and have two pitchers viewed as roughly equal to Vazquez. The Mets are losing staring catcher Wilson Ramos to free agency. So that leaves Anthony Senzatela, Kyle Freeland and David Peterson as the best options. Any preference? (Personally, I go Senzatela here. But there is no wrong choice yet IMO.)
If you're expecting Bloom to add some budding star like Tony Gonsolin or Ian Anderson or Aaron Civale for Vazquez, it's not going to happen. In fact, even one of thee three named above might be unlikely, especially if their respective GMs don't see Vazquez as being an immediate solution...
