text: if the kansas city royals and the pittsburgh pirates were to switch leagues, would the team improve? this mean that the kansas city royals become a part of the national league central division and the pittsburgh pirates become a part of the american league central division.  i think that pittsburgh would improve but kansas city would not. first of all, kansas city is in missouri a misnomer in its self. the pirates would be in with white sox indians, tigers and twins.kc would be in with cubs, brewers,cardnials,stros,and reds.kc would be switching to a six team division.natural rivalry all the way around.so, kc would be way worse off. but, it doesnt really matter since both teams are mathimatcally eliminated by the end of april.
