Model: 3-season decay-weighted blend of xwOBA / xERA (Savant), with wOBA / FIP fallbacks from MLB Stats API if xStats aren't available. Batter tiers are calibrated per position; pitcher tiers per role. Small-sample players are regressed toward the position/role league mean and flagged with a shrinkage indicator.
