He certainly doesn't seem to be healthy. He can't play the field. And he's stiff. Like those mid 50s guys that play softball. I guess if this is him healthy, then that's a bigger problem.
I feel like Polanco is a guy who's shown us what he is. When healthy, he's a guy that will give you a mid to upper 700s OPS, and will play multiple positions, but none of them well. When he's not healthy, he's not productive. And he's usually not healthy. Even in 2025, his "healthy" season, he only played 138 games.
I don't think anything he does these last 40 games should change how we view him for 2027. And I agree it's foolish to count on him as a starter. I think the focus should be to get him as healthy as possible, and hope he manages to stay on the field for 100 games or so.
