Paul & all on net54,
Thanks for posting that today.
The second seller David Maus also reached out to me with the same explanation last night and this morning.
Following his logic and checking the original Nats schedule for 1918, I must say that I concur with his belief that game 11, did in fact, coincide with the Ruth- Walter Johnson game that he referenced in his auction. The two rainout or inclement weather cancellations that occurred in Wash early in their schedule in 1918 created the disparity in the result.
I must say that I'm always amazed at how much there still to learn in this hobby even when you've been at it for so long. I continue to learn every day...

Thanks to all that contribute to the journey.
