Joe Williams
The most dominant pitcher you've never heard of posted a microscopic 1.14 ERA in 1918 — a performance 148% better than league average that ranks among the greatest single seasons in baseball history. Joe Williams spent his prime years barred from the majors due to segregation, carving up Negro League lineups with a devastating fastball that earned him induction into Cooperstown six decades after his retirement.
Williams compiled a 2.57 ERA across 23 seasons while striking out nearly seven batters per nine innings — elite numbers for his era when strikeouts were far less common. His 143 career ERA+ demonstrates sustained excellence that would have made him a household name in any integrated league.
The dual-threat nature of his game adds another layer of intrigue. Williams hit .297 over 728 at-bats, contributing 15 home runs and 121 RBIs when called upon. Few pitchers in any era have matched his combination of mound dominance and offensive competence.
