Hmm. I think I've figured out the Red Sox:

( Early December, 1916: )

( Late December, 1916: )

( July 16, 1918 )

( September, 1918 )

Conclusion:

Rasputin's curse on the Romanovs may not have completely worked, because of the possible survival of Anastasia. This means that there was some unused curse vibes floating around in the second half of 1918. Those curse vibes hit the Sox and stuck.

So, therefore, in order to have the Sox win a Series, we clearly have to reinstate the Tsars.

Hey, they can't be significantly worse than any of the other governments Russia has gone through. . .
