I knew Hunter Dozier was having a nice year but looking closer at his statistics it seems he could have one of the best offensive second years in Kansas City Royals history. While researching I did limit this to players who played their rookie and sophomore years as a major league player with the Royals.
Players that had intriguing statistics but not enough to make the list include Steve Balboni drilling 36 home runs in 1985 (a Kansas City single-season record until Mike Moustakas surpassed that in 2017), Bo Jackson hitting 27 home runs and stealing 25 bases in 1988, Mark Teahen knocking 18 balls out of the park in only 109 games in 2006 and Adalberto Mondesi swiping 32 bags and slugging 14 home runs in only 291 plate appearances just last year.
