Fielding Run Value is Statcast’s metric for capturing a player’s measurable defensive performance by converting all of Statcast’s
individual defensive metrics from different scales onto the same run-based scale, which can then be read as a player being worth X runs above or Y
runs below average. Currently, the conversions for those metrics are as follows. (Unless otherwise noted, all metrics are available since 2016.)
How to read it: In 2024, Andrés Giménez had a Fielding Run Value of +17 runs, which came from 14 runs on range and 3 runs via his involvement in double plays, making him the most valuable defender in baseball among non-catchers that season.
