Why does the model favor STL?

KC key absences: Carlos Estévez (RP, Out, 5.0pt impact); Cole Ragans (SP, Out, 5.0pt impact); Kris Bubic (SP, Out, 5.0pt impact) — total ~20.0pt swing. Louis Cardinals is 40-32 (0.556). Kansas City Royals is 30-45 (0.400).

What could go wrong with the STL pick?

Carlos Estévez's absence hurts Kansas City's bullpen, but if the Royals' bats stay hot at 5.1 RPG, they could overcome the injury deficit.
