Royals Killers

The Baseball Reference Play Index, one of the seven wonders of the modern world, has a new batting splits function (currently in beta) that I've of course fallen into a wormhole playing with. Below are a bunch of lists of the hitters who have faced the Royals the most or done the most damage against them. First up are the top 20 players by plate appearances against the Royals and their stats in those PAs:
