Twins catcher-turned-first baseman Joe Mauer has some advice for Giants All-Star Buster Posey: Play catcher as long as you can, and enjoy doing it. 

"There will be a day when he can't catch anymore and a day where we can't put the uniform on anymore," Mauer said before the Twins played at San Francisco on Friday night. "He's a special player and he'll be able to make that transition if he wants to. I'd like to see him catch as long as he can."
