Roger Clemens

Roger Clemens blended longevity, power pitching, and peak dominance into one of the strongest resumes ever. He won seven Cy Young Awards across different eras of offense. Clemens sustained elite strikeout rates while limiting walks during his best seasons. His career 143 ERA+ across 24 seasons demonstrates sustained superiority. He adapted from power phenom to crafty veteran without losing effectiveness. Clemens thrived during the high-offense 1990s and early 2000s, which strengthens his case. He delivered multiple 20-win seasons with ace-level workloads. His postseason record includes strong championship contributions. Few pitchers matched his ability to dominate across decades. As a combination of peak and longevity, Clemens sits near the very top.
