Pennant Run Research

Baseball intelligence

Fielding Run Value (FRV) explained

Baseball Savant’s retained accumulated defensive run value, with source coverage kept separate from position-specific rates and comparisons.

Definition and interpretation

The provider’s retained season Fielding Run Value total; do not add its constituent run components again.

Positive values represent defensive runs above average. Source season totals are separate from exact-position FRV rates and from OAA-derived range runs.

Coverage and limits

Capture time is not a verified game cutoff. DRS is a separate provider metric. Pitcher FRV is not measured, and source totals are not automatically simulation inputs.

Source-defined coverage; no new percentile cohort.

Explore available values and percentiles in Leaderboards or in the exact-season Scouting Report. Missing evidence remains unavailable; small samples retain provisional ranks.
