Phil Niekro competed at the highest level until age 48, not by overpowering hitters but by throwing a knuckleball that seemed to move in slow motion. This episode explores how a backyard trick pitch, learned by his coal-miner father from a fellow miner, turned into 318 major league wins and a plaque in the Baseball Hall of Fame.

We break down the fluid dynamics that made the spinless pitch a nightmare for hitters and catchers alike, the low-impact mechanics that preserved his arm, and the paradoxes of his career, including a 1979 season where he led the league in both wins and losses. His 300th win came in a shutout where he withheld his signature pitch until the final batter.
