Last night, while I wasn't sleeping after that game, I went back and looked at it. Based on Fangraphs ZiPS and WE%:

-They had a 13% chance of beating the Brewers in the bottom of the 8th with 2 outs

-Then they had a 26.3% of winning the series against the Dodgers after losing Game 3 of the NLDS. Then during Game 5, the Nationals had a win expectancy of 11% in the middle of the 7th.

-So now, down 3-2, they sit with a 21.2% after losing Game 5 to the Astros. I think for ZiPS projections they were penciling in Scherzer as the Game 7 starter, so it's probably much less than that.

It's been a pretty wild run to get down in the 10% range twice in an elimination game and advance from that. This was after their playoff odds dropped to 22.2% at their low point during the season. Not sure how much gas is left in the tank at this point though but it's been damn memorable.
