I'd settle for Simmons at 1yr/$5M, only because I agree with the response above about the value of continuity up the defensive middle. I would hope that all stones are unearthed before doing this though. Obviously, the gold stones have already been taken, don't appear to be of interest or may just be pyrite.
Iglesias seems to be a popular fallback, but his dramatic fall in UZR is a concern. Is that an outlier at age 31 or just good old fashioned decline? He was much worse than Simmons in that regard in '21. His bat was quite a bit better, so maybe it's a wash.
I'm definitely in the camp that Polanco is the second baseman going forward. I see that position as locked up through 2025, and I hope his ankle holds up enough that he can end up being a Twin for life.
