I read somewhere that Sano has not taken much infield practice this year, and I doubt that Mauer has taken any outfield practice. Maybe they should have taken such practice and maybe they should start taking such practice, but in the meantime I would be reluctant to ask them to play a position that they have not played for a long time. I would have put Park at 1B and given Mauer some rest against a lefty. Or maybe Park could have played in LF?
