42 45 59 60 91 305 | Jack Roosevelt Robinson and Game 7 of the 2017 113th World Series, the "race" code

*The part about the 59th loss is incorrect, disregard that.

91 is the 13th triangular number.
LA could get their 13th World Series loss.  LA = 13

Dodger Stadium = 59; Jack Robinson = 59; Negro = 59; Slave = 59; Blues = 59
Rodney King = 59; beat March 3, 1991

Notice November 1 leaves 60-days left in the year.

Nigger = 42 / 60
Jackie = 42

The World Series began on the 45-year-anniversary of his death.

Major League = 45

It's amazing how it all lines up.
