A quick update. We are working on the 2021 Season Library. An early release will be ready this week. This release will have everything that the other season libraries have (e.g., real-life transactions, L/R splits, etc.) except for the as-played lineups. We are waiting for Retrosheet to publish their Game Logs for 2021, which typically happens around Thanksgiving. As soon as the Game Logs are released, we will update the 2021 library accordingly.
We are also trying something different this year. We will be creating a 2021 playoff library that contains playoff rosters and actual lineups for the entire 2021 postseason. This should be available about a week after the 2021 World Series.
