As of this moment, five teams in the NL Central have given up between 177 and 179 runs inclusive, from the 26-16 Brewers to the 19-23 Pirates. (The last place Astros have given up 191.) Atop the AL Central, the Tigers and Royals have also given up exactly 179. If the Cardinals had given up two more runs to this point, then the four best NL Central teams would have given up exactly 179, making the six best teams in the heartland at the same runs allowed figure.
Whoever asked for competitive balance may have gotten it. Harrison Bergeron, eat your heart out.
