Of course, the reason for that is completely explained by the bottom.
The bottom team in the Central is the Reds with a record of 53-58 with a run differential of +28.
The anchors in the other divisions are the Marlins (42-70, -140), Rockies (41-71, -172), and Nats (51-61, -56).
Unless something changes no Central team will get one of the 3 wild card spots for the second year in a row
