What is this: Each throw from 2B/SS/3B is given an out probability based on inputs including throw location (high/low, wide/on-target, bounce/in-air), runner speed on play, and runner location from first base at the point the 1B catches the ball. Only throws within an 8 foot perimeter of the 1B bag are considered in the model. Click here for a more detailed explanation of how this metric works.
