Example prompt: Can you pull up the 2023 NPB fielding stats for 源田壮亮 — I want to see his defensive numbers across all positions he qualified for this season.

## When to prefer this

Use this endpoint when you need fielding statistics for a specific named NPB player (rather than the full positional leaderboard). Ideal for scouting individual defenders, evaluating utility infielders who appear at multiple positions, or building fantasy baseball defensive profiles. Prefer the full fielding rankings endpoint when you want all qualified players at a given position, and use this endpoint when you already have a player name and want their stats quickly.

## Known failure modes

- Player name not found — returns empty position arrays and match_count of 0
- Invalid season year format — API error or empty response
- Player did not meet 規定試合数 (minimum qualifying games) — not included in results
- URL-encoding issues with Japanese character names — no match returned
- Network timeout or Railway.app hosting downtime — connection error

## How this service works

Japanese baseball (NPB) individual fielder stats lookup by season + name (case-insensitive partial match). Returns single-player subset across all positions (1B / 2B / 3B / SS / OF / C / P) from the official BIS fielding ranking (規定試合数 met only). Use cases: NPB defensive matchup analysis, multi-position player evaluation (e.g. utility infielders), agent-driven scouting, fantasy baseball defensive contribution lookup. Cheap subset price ($0.003). Input: :season (YYYY) path param + ?name=<query string> (URL-encoded, JP or EN). Output: JSON {season, league, category:"fielders", subleagues:{central:{positions:{matched_pos:[player]}}, pacific:{...}}, match_count, query_name}. Pay-per-call $0.003 USDC on Solana mainnet.

## Output

A JSON object containing the season, league, category (fielders), and a subleagues object with Central and Pacific league breakdowns, each listing matched player fielding stats by position. Also includes match_count and the original query_name.
