I'd rather wait one more year when the MLB free agent class at shortstop has potential to be absolutely stacked. Francisco Lindor, Javier Báez, Carlos Correa, Corey Seager and Trevor Story are all scheduled to become free agents next offseason. Of course there's no guarantee all guys make it there without signing extensions with their existing teams, but this is why I don't see a need to rush into a risky trade this offseason.
A little patience with our prospects has potential to pay off very nicely. And if you let a guy like Groshans mature a bit more in the minor leagues, his trade value is only going to increase as he gets closer to MLB ready, provided of course he continues to improve as expected. I don't think Austin Martin is very far away, I suspect he'll be up by early 2022. This is a guy with a 65 hit tool and athleticism to match. Here's what Keith Law has to say about his potential as a third baseman:
