Walk-Back & MLB-Readable Rates

Walk-Back Stop% measures how often this pitcher strands the post-HR rule-placed runner on 3B. The bonus run, when it scores, is unearned (Manfred-runner precedent) and is excluded from ERA but charged to runs allowed (and thus to wERA).

20-80 scout grades. Primary pitch comes first; usage weight (% of typed pitches in neutral counts) drives ordering. Release angle, count, and platoon further bias which pitch fires each PA — see o27/config.py:PITCH_CATALOG.

Plays are attributed to a fielder by position-weighted probability per BIP type (grounders cluster at SS/2B; flies at CF; etc.). Errors get charged to the responsible position. Assists and double plays aren't yet tracked separately — only PO and E.

Crossover (XO) Stats

O27 rate stats translated to MLB-readable values via mean-and-spread z-anchoring (formula: xo = MLB_mean + ((value − O27_mean) / O27_sd) · MLB_sd). The map preserves rank order exactly — XO leaderboards are the same player order as native — and preserves spread, so an elite O27 player shows up as an elite MLB-equivalent number rather than bunched at the league anchor. Read these the way you would read MLB stats; if a pitcher's XO ERA is 3.10, that's the MLB-equivalent of a 3.10 ERA.
