Looked at from a certain angle, the 2013 Royals team was a dead ringer for the slightly more lauded 1985 squad. The above graphic charts every Royals team by run prevention and run scoring as compared to that season's AL average. (The actual formula is (RunsPerGame / ALavgRunsPerGame)*100.) Lower is better for run prevention, higher for run scoring. As you can see, 2013 and 1985 are right on top of each other, and are the two most run-preventingest teams in Royals history. A closer look at the similarities:
