Percentile snapshot
1978 season — qualified batters
of 140 qualified 1978 batters (min 502 PA)
Career, era-adjusted
sWAR measured against every career in history, 24,011 of them. Only era-adjusted career stats carry a percentile — a raw career total gets a rank instead, because pooling the 1890s with the 2020s is a choice, not a measurement.

Career totals
A total is called out only where it ranks in the all-time top 500; hover a figure for its rank and the size of the field it was ranked in. Ranks are absolute facts and carry no percentile — the population for "career home runs" would be an editorial choice, and the rank is not.

Ranked from our own play-by-play game log, which begins in 1901 — not from the record book, so a career played outside it shows nothing here rather than a short list.
