Every career total and season line is computed from the SABR / Sean Lahman baseball database (2025 edition, CC BY-SA 3.0), the same source behind our historical position leaderboards. Rate stats use league-season normalization only (OPS+ and ERA+ as marked, never park-adjusted); unrecorded early-era values stay absent rather than being invented. Career totals sum only what the source records.
Award winners and MVP / Cy Young / Rookie of the Year voting history come from the same database; the year pages live under MLB award voting history. Official transactions (2011 to the current season) come from the MLB StatsAPI feed on our transactions archive.
