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 xRA).

Repertoire

Cutter 44 Changeup 66 Knuckleball 58 Screwball 37 Gyroball 41

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.

Arsenal — in-game usage

FB%	BR%	OFF%	1B	2B	3B	HR
40%	30%	66%	5	4	0	1

FB/BR/OFF are the pitcher's per-game pitch-mix averaged across appearances. 1B/2B/3B/HR are the actual hit shape allowed — driving the per-pitcher xRA v3 split.

Defensive Profile (rated)

Defense (overall)	46 Average	Position-aware blend of general defense, arm, and position-specific glove
General defense	46 Average	Glove / surehandedness — applied at any position
Arm	43 Below Avg	Throwing strength — matters most at C / OF / SS
Infield (1B/2B/3B/SS)	50 Above Avg	Position-group sub-rating
Outfield (LF/CF/RF)	50 Above Avg	Position-group sub-rating
Catcher	50 Above Avg	Position-group sub-rating

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.
