Hardest Grand Slam Title Runs in Tennis History

Which champions faced the toughest road to glory? Our Draw Difficulty Index (DDI) ranks title runs based on opponent seeding and match load, revealing the most grueling paths to Grand Slam victory.

How is DDI Calculated?

The Draw Difficulty Index combines three weighted components:

Seed Difficulty (45%)

Higher-seeded opponents beaten = higher score

Seed Density (20%)

Percentage of matches against seeded players

Fatigue Score (35%)

Total sets and games played throughout the tournament

Walkovers and retirements reduce the score via the Draw Integrity Modifier (DIM). Learn more about our methodology
