In the timeframe of your following MLB, which 1st baseman has been the most dazzling defensively?

I have been following baseball for a long time and I've seen a lot of great defensive first basemen. They're usually a minority because teams like to reserve that spot for a slugger. The three best I've ever seen were Wes Parker of the Dodgers in the 60's. Keith Hernandez with the Cardinals and the Mets and the Yankees Don Mattingly. I have heard that a guy from the late 50's and early to mid 60's was pretty good too. His name was Vic Power and he won 8 straight Gold Gloves at 1B
