Phil Niekro
The only knuckleballer to win 300 games: a Hall of Fame career built on the one pitch nobody, himself included, could fully explain.
Signature pitchKnuckleball
They called him Knucksie. On a floating knuckleball his father taught him, Phil Niekro pitched more innings than any pitcher who started in the live-ball era and threw deep into his late 40s, long after a fastball would have left him. The knuckleball is usually a last resort; for Niekro it was a 300-win, Hall of Fame career.
The signature pitch
A true no-spin knuckleball: he arched the first two fingers of his right hand so only their tips and nails touched the ball, removing almost all imparted spin and letting the seams and the air do the rest. The pitch fluttered late and unpredictably.
The fingertip-and-nail grip description is from the FanGraphs remembrance; he learned the pitch from his father and from minor-leaguer Nick McKay (SABR).
The mental edge
Trust as a weapon. Teammate Dale Murphy called him the ultimate gamer and competitor, and the record bears it out: the most innings of any live-ball-era starter, and the oldest pitcher ever to throw a shutout, at 46 years and 188 days, a mark that stood nearly 25 years until Jamie Moyer passed it.
The "ultimate gamer" characterization is Murphy's, via FanGraphs; the longevity records are from Wikipedia and the Hall of Fame.
“I figured if there's any way I'm going to win my 300th game by striking the guy out, I was going to do it with the pitch that won the first game for me.”

The record
Three hundred wins and three thousand strikeouts on a pitch most pitchers will not trust for an inning, and a Hall of Fame induction in 1997 — he is still the only knuckleballer ever to clear three hundred.
Nobody who started in the live-ball era pitched more innings. At forty-six he became the oldest man ever to throw a shutout, a record that stood for nearly a quarter century until Jamie Moyer finally passed it.
The numbers live with the record-keepers.
The record is told here the way the rest of the atlas is told: in prose, each claim confidence-labeled and one click from its source. Where reputation and record disagree, the gap is shown, not smoothed over.
