Personally I think it would have been interesting to see how Nieves handled Bergmann... I feel like his demonstrative and animated approach to calling games would help Bergmann keep his head in it, but I guess it makes more sense to have Berg pitch to someone who has more experience handling him.
Now that I think of it... does anyone know who he pitched to in Columbus and what his numbers with diff catchers were? I suppose I should know but I honestly don't follow the minors at all except for major headlines and what I read on this board
