Best Fielding First Basemen

You don't really notice a great fielding first baseman as much as you notice crappy ones.
Maybe the worst fielding first baseman I've ever seen is Jason Giambi. He has no flexibility and he throws like my grandma. And she's dead.
In the previous post, I wrote about Todd Helton and how his fielding has never suffered, despite injuries limiting him offensively.
Of all the first basemen I've seen in my lifetime, the best defensively was Keith Hernandez followed closely by Don Mattingly. Then I would throw Todd Helton in right behind them. There are a lot of good fielding first basemen but I'd take those guys in a heartbeat over anybody.
Am I missing anybody?
