What are the odds:
An umpire will call more balls than strikes in a MLB game.
Balls/strikes rate, or walks/strike outs rate, will identify facets of color discrimination bias.
This color bias will filter through pitch selection, filter through pitcher's ability or arm strength, filter through umpire's strike zone consistency, and deliver an absolutely clear causal-effect relationship.
Another econometric swing and a miss.
