Back when the late Harmon Killebrew was broadcasting Twins games, he mentioned a couple of times he thought the outfield was the better place for long term player health, because players don't have to do all the bending and twisting, etc., that infielders have to do. We can speculate all we want about Sano's attitude and ability, but, in the end, we won't know anything until we actually see Sano play.
