Hard to know what the team has in Alvarez Jr. The bat seems like it could be useful with swing changes that get him to elevate more, especially since he has solid plate disciple and bat control; but there’s still probably not enough offense there to be a regular at 3B, even with the very good defense he’s shown at the hot corner. Certainly not enough offense to start over a healthy Riley. And it’s hard to carry a bench bat that only backs up 3B (and, I suppose, 2B).
Maybe some other team with a dearth of 3B options would value the glove as starter-worthy if the bat is at least viable? Again, difficult to see what to do with him going forward.
