What is Run Value (RV)?
Run Value measures how much a pitch outcome changes the expected runs in a game.
Positive RV for a batter = good (they're generating offense). Positive RV against a pitcher = bad (they're giving up offense).
RV/100 normalizes per 100 pitches seen/thrown for fair comparison.
How Arsenal Edges work: When a batter with a high RV against fastballs faces a pitcher whose fastball has a high RV allowed, and that pitcher throws their fastball 40%+ of the time — that's a concrete, pitch-level HR edge that goes beyond general HR/FB rates.
Pitch families: Hard (Fastball, Sinker, Cutter) · Breaking (Slider, Curveball, Sweeper) · Offspeed (Changeup, Splitter)
