MLB Research Tables and Stats

PayDirt is built on statistics and models that everyone can use, and these research sheets are no different! The MLB Research tables are built to give you insight into unique metrics and stats to help your decision making process. For the most part, the stats that you find here will be different than places like Fangraphs or Baseballsavant. These tables contain the same baseline sets of data used in the powerful MLB Range of Outcomes models. It's important to note that these stats are based on a recent rolling sample from the year, not the full season! If you have any questions, feel free to join the discord or reach out on twitter!
