Billy Butler is back in Kansas City for a three-game series at his old baseball home this weekend. Through some combination of happenstance and serendipity, the schedule gives him the perfect reunion. Including the 2014 playoffs, in which the Royals beat Butler’s new team, the A’s, and the 2012 All-Star game, Butler has played 595 games at Kauffman Stadium. But, always in a blue and white uniform. Always from the first-base dugout.
