How this works:
The susceptibility score is a composite ranking using
real season stats from FanGraphs: HR/FB% (30%), official HR/IP (25%), total HRs allowed (20%),
and FIP-xFIP gap (15%), plus a 10% boost for pitchers who give up HRs to batters in our scored pool.
FanGraphs season columns come from the loaded season cache or a validated snapshot; the THR scored-pool component is filtered through the selected date.
Historical reconstructed views are directional only unless a validated pre-game snapshot is available.
Pitchers qualify with at least 2 starts or 10 IP (546 qualify in this view).
The top 10 are flagged with a 🎯 icon
directly on the main slate table — so you never miss a soft matchup.
