Sources & coverage
Each season link opens that original year and period club. Historical club names, leagues and relocations follow the verified source records. W–L% is the reported winning percentage; ties remain separate. Division and league ranks retain their source scope; postseason figures appear only when supplied. No playoff qualification, championship or missing value is inferred. An em dash means the field is unavailable in this table.
Completed season records through 2025. The separate 2026 link opens current season coverage.
