+## PR #51: fix: compute CSV after appending data row in get_one_player
+
+**Verdict:** APPROVED (posted as COMMENT — Gitea blocks self-approval)
+
+**File reviewed:** `app/routers_v2/players.py`
+
+**Root cause:** `return_val = DataFrame(data_list).to_csv(...)` was called before `data_list.append(player_data_row)`, so the CSV only ever contained the header row.
+
+**Fix:** Moved `to_csv()` call to after the `data_list.append(...)` block. Minimal, correct, single-line reorder.
+
+**Notes:**
+- No security issues
+- No test suite in this repo
+- Pre-existing style note: using header as first list element + `header=False` is non-idiomatic pandas, but out of scope
+- Branch: `ai/paper-dynasty-database-12` → `next-release`
