3+ years of Brad Hand, who was valued at 3.3 fWAR total in the two previous season was traded with Adam Cimber gor a two time top 3” prospect Francisco Mejia.
Two years of Kirby Yates, valued at 2.3 fWAR over the two previous seasons, won’t get you anywhere near a top 30 prospect, unless they drastically up the additional piece over Adam Cimber.
The Padres could use a 3b, but the Sox are a tough match. Devers is worth far more than Yates, Dalbec isn’t a major leaguer and might not be as good as a few Padre infield prospects. And Chavis is a butcher at third.
San Diego also isn’t looking for prospects as far as anyone can tell. They have those by the bushel. They would probably prefer a third team involved who might have interest in Chavis’bat and a 3b they can move. Matt Duffy of Tampa might be a good fit if 1) Tampa had some interest in Chavis, which they might since he can hit and doesn’t make much money, and 2) Tampa was willing to be involved in a trade with Boston. One thing we have learned about Tampa is, they do seem to like 3 team trades...
