We focused on this period because it's right during the alleged year(2017) that Houston was concluded (by the report) to have been taking part in the sign stealing scandal. It's also alleged that the 2018 Boston Red Sox used a sign stealing mechanism BUT that's currently under investigation.
Now it's important to note that they have not been concluded to have actually been participating in the in 2018-2019 in which no report has been filed as the commissioner's report only called out the 2017 season for the Houston Astros. Not the 2018-2019 seasons of the Red Sox or Astros. If you want to see the significance again of the ZScore and what it can be telling you, please
see:https://baseballfan999.wixsite.com/baseballdat/post/what-does-the-zscore-tell-you The total comeback wins/blown leads split out between 1st and 2nd half of season:
