MLB playoff odds are based on 25000 simulations of the rest of the season and playoffs. The team's estimated quality is determined by their performance over their last 100 regular season games (even if it spans seasons) and includes a regression to the mean factor. These results are based on standings through 1910-10-15. This page does not update during the postseason.
