This Weekend Was Wild. I Did the Math To Prove It.
Hang it in the Louvre:
Oh, and this one too:
The playoffs were absolutely wild this weekend. Out of the six games played Saturday and Sunday, two were all-time classics. First, the Yankees and Royals traded blows before Alex Verdugo produced a game-winning single after a controversial stolen base call. Then the Phillies and Mets traded home runs and blown leads right up until the last play of the game, Nick Castellanos’s walk-off hit.
If you wanted to, you could read our game stories for these games, or any number of other fine pieces about them across the internet. You could watch highlights or condensed recaps. But this is FanGraphs, so I thought I’d cover another angle: where these games fit in the history of wild playoff games.
We have win probability charts going back to 2002, which means we have data on total win probability changes going back to that year as well. If you take the absolute value of these and sum them up, you can see exactly how much each team’s fortunes changed throughout the contest. The more total win probability changes, the wilder things are. For example, the least exciting game by this measure occurred on October 9, 2019. The Cardinals beat the Braves 13-1 in the NLDS, and they opened things up by scoring 10 in the first inning. No drama, and thus very few changes in win probability. A 2023 contest between the Diamondbacks and Dodgers (11-2 Arizona, 9-0 after two innings) is the runner up.
