The career totals are staggering — 428 wins, 5,295 strikeouts, 14 no-hitters, and two perfect games over a span of 33 years — and they’ve all been documented by a network of researchers unearthing primary sources. But only a fraction of those are on Seamheads, and an even smaller fraction on Baseball Reference, covering his time in the major Negro Leagues. John Donaldson is an enigma.

He barnstormed before the major Negro Leagues were in place, dominating the competition, spent five seasons (1920-24) with the Kansas City Monarchs (whom he’s said to have named) of the first Negro National League, primarily as an outfielder rather than a pitcher, and then spent over a decade and a half continuing his barnstorming odyssey on integrated and Black semiprofessional teams.
