Top 100 Best Pitchers of All-Time in MLB History

When you think of baseball immortality, pitchers often steal the show.

They command the game from 60 feet, 6 inches away, dictating tempo and dismantling lineups with nothing but precision and guts.

But who are the greatest pitchers of all-time? It’s a question that sparks endless debate among fans, analysts, and historians.

Some argue for career-dominating pitchers who sustained excellence across decades.

Others champion peak brilliance, those who reached heights few could match, even if just for a few seasons.

This ranking considers both. We’ve evaluated the best pitchers of all time using career WAR (Wins Above Replacement), seven-year peaks, three-year peaks, five-year prime windows, and postseason success.

The result? A definitive list of the 100 greatest arms in baseball history, from deadball-era legends to today’s active aces.

Frequently Asked Questions About the Greatest Pitchers of All-Time

• How are the greatest pitchers of all-time ranked?

Pitcher rankings combine multiple factors: career WAR (total value), seven-year peak WAR (sustained excellence), three-year peak WAR (absolute dominance), five-year prime WAR (consecutive peak years), and championship WAR (postseason success). These metrics are synthesized into a Player Score that adjusts for era, ensuring fair comparisons between pitchers from the 1900s and today’s game.

• Who is the greatest pitcher in MLB history?

Walter Johnson ranks as the greatest pitcher of all-time based on this comprehensive methodology. The “Big Train” accumulated 167.8 career WAR from 1907-1927, combining extraordinary longevity with peak dominance that remains unmatched. His 507.4 Player Score reflects both sustained excellence and era-adjusted performance across 21 seasons.

• Which modern pitchers rank among the all-time greats?

Greg Maddux (2nd), Randy Johnson (3rd), Tom Seaver (4th), and Pedro Martinez (6th) lead modern-era pitchers who played primarily in the 1980s-2000s. Among currently active players, Justin Verlander ranks 18th all-time, Clayton Kershaw 19th, and Max Scherzer 23rd. All three have legitimate Hall of Fame credentials and could move higher depending on how they finish their careers.

• Why are there so few relief pitchers in the top 100?

The ranking methodology emphasizes career and peak WAR, which naturally favors pitchers who accumulate more innings. Starting pitchers throw significantly more innings than relievers, giving them more opportunities to accumulate value. Mariano Rivera (95th) is the only pure reliever in the top 100, though his postseason dominance (29.4 championship WAR) and unmatched closing ability earned him that distinction despite fewer innings.

• What makes a pitcher’s peak performance as important as career totals?

Peak performance shows how dominant a pitcher was at their absolute best, which matters when evaluating true greatness. Sandy Koufax’s relatively short career (49.0 WAR) placed him 34th overall, but his seven-year peak WAR of 48.7 demonstrates brilliance that rivals anyone. The ranking balances peak with longevity because both matter—sustained excellence proves consistency, while peak performance proves ceiling.

• How do Negro League pitchers factor into these all-time rankings?

Negro League legends like Satchel Paige (27th), Joe Williams (45th), Bullet Rogan (74th), and Martin Dihigo (79th) appear throughout the list based on available data and historical accounts. Their statistical records are incomplete due to the segregation era they played in, which means these rankings likely undervalue their true greatness. Historical testimony from those who saw them pitch consistently describes dominance matching or exceeding their major league contemporaries.

Conclusion:

The greatest pitchers of all-time share a common thread: they made hitting look impossible when they had it working.

From Walter Johnson’s blazing fastball to Greg Maddux’s surgical precision, from Pedro Martinez’s devastating changeup to Mariano Rivera’s unhittable cutter, these 100 pitchers represent the pinnacle of baseball mastery.

This ranking balances career value with peak dominance, rewarding both the workhorses who gave you 200 innings every season and the flamethrowers who reached heights most can only dream of.

Whether you favor longevity or brilliance, championship pedigree or pure stuff, this list captures the full spectrum of pitching greatness.

The beauty of baseball is that excellence transcends eras. Walter Johnson would be elite in 2024, just as Clayton Kershaw would have dominated in 1924.

The best pitchers find ways to beat the best hitters, regardless of when they played.

As active stars like Verlander, Kershaw, and Scherzer continue building their legacies, they’re chasing immortality alongside names like Seaver, Martinez, and Johnson.

The conversation never ends—it just makes room for new legends while honoring those who came before.
