What team does Greinke retire under?

So we can all agree that Zach Greinke is a future Hall of Famer, right? But what team does he retire under (if any)? He's a rare case because I don't think many HoF'ers have played for as many teams as him. He spent the most time on the Royals but won the Cy Young with them but he was arguably at his peak with the Dodgers and could've probably won a second Cy Young. He made the world series with the Astros in 19 so they're possibly a possibility too. Does the the individual player get to decide what team they retire with? If you ask me I'd say 90% he's going in as a Royal but you never know
