When the Hiroshima Carp lost Game 1 of the Central League Climax Series Final Stage, they found themselves trailing 2-0 in the six-game series. Ditto for the Chiba Lotte Marines in the Pacific League.
The math doesn't quite add up there, and it becomes even more absurd when you consider that this is what NPB officials came up with as a way to decide a champion.
In the final stage of each Climax Series, NPB gives each league's champion a one-game advantage in addition to home-field advantage throughout.
