These seasons were much shorter. In 1937 a Negro Leagues team played about 51 official games while an American or National League team played about 155. The totals above add those seasons up exactly as they were played — no conversion, no pro-rating, no adjustment of any kind — which is why the league subtotals are there. Rate statistics like batting average and ERA do not depend on how many games were played, so they compare straight across the table.
The WAR columns are worked out on this site — they are not part of the source data, and they will not match Baseball-Reference exactly.
Everything else on this page comes straight from the Lahman database. WAR is our own calculation from those same season lines: fielding is estimated from putouts and assists rather than measured, fielding innings are missing before 1954, and the fielding component is capped. Treat it as a reasonable estimate of value, not as a record. The season tool explains the method in full.
— means the value is not in the source for that season, which is not the same as zero. In the Career and Subtotal rows it marks a statistic that cannot be added up across seasons — wOBA and FIP both need league constants that change every year, so we leave them blank rather than invent one. Leagues on this page: NEG (Negro Leagues).
