ERA+ measured against qualified careers (1,000+ IP), 1,334 of them; 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.

sWAR is the season TOTAL for a player who both hit and pitched: the record book carries one figure per season, not a split, so the same number appears on both lines rather than being counted twice.

239th-highest career K/9

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.
