The Nervous Nineties: Fact or Fiction?
Are the final ten runs to a century really the hardest?
The CricBubble verdict
Bubble Burst — Debunked
The data contradict the idea that Test batters generally slow down in the nineties.
01 — The claim
Batters consistently slow down as they approach a century.
02 — Why it matters
Are the final ten runs to a century really the hardest? This is the question our investigation will evaluate.
03 — How we'll test it
Compare ball-by-ball strike rates in the 80s, 90s and immediately after 100; control for match situation.
04 — Evidence & sources
- Researchers analysed ball-by-ball data from 712 Tests played between 2004 and 2022.
- Runs per ball and boundary probability increased as batters approached 100.
- After reaching 100, runs per ball fell by an estimated 0.18.
- Boundary probability also fell by about 3 percentage points after the milestone.
- This describes an average pattern in the studied Tests, not every batter or format.
