Walter Johnson

Walter Johnson set the gold standard for early 20th-century pitching dominance. He overpowered hitters with elite velocity in an era that did not regularly see it. Johnson accumulated 417 wins while maintaining run prevention that crushed league averages. His 147 career ERA+ across massive workloads proves the dominance was not empty volume. He led the league in strikeouts 12 times, showing rare swing-and-miss ability for his era. Johnson consistently carried mediocre Washington teams with complete games and durability. He combined workload and effectiveness in a way few pitchers ever have. Even adjusting for era, his gap over contemporaries remains enormous. He thrived in postseason opportunities when finally given support. As a career-value and dominance blend, Johnson remains the prototype of an all-time ace.
