Test cricketers score quickly during the 'nervous nineties': Evidence from a regression discontinuity design

Area of Science:

• Sports Science
• Performance Analysis
• Psychology in Sports

Background:

• The 'nervous nineties' is a widely accepted concept in cricket, suggesting mental challenges for batters nearing 100 runs.
• Empirical research examining batting behavior changes around the 100-run mark in Test cricket is lacking.

Purpose of the Study:

• To investigate how batting performance and behavior change as players approach and surpass 100 runs in Test cricket.
• To statistically analyze the 'nervous nineties' phenomenon using historical data.

Main Methods:

• Utilized opensource ball-by-ball data from 712 Test matches (2004-2022).
• Employed multi-level regression modeling to analyze batting performance metrics (runs per ball, boundary probability, dismissal probability) around the 100-run threshold.
• Adjusted models for data clustering (balls within players, matches within players, innings within players).

Main Results:

• Runs per ball and boundary scoring probability significantly increased as batters approached 100 runs.
• Post-100 runs, there was a notable decrease of -0.18 runs per ball and a 3% drop in boundary probability.
• No significant change in the probability of dismissal was observed before and after reaching 100 runs.

Conclusions:

• Test cricketers demonstrate effective coping mechanisms for the psychological pressure of the 'nervous nineties'.
• Batters tend to adopt more aggressive or opportunistic strategies to swiftly achieve the 100-run milestone.
• The data suggests psychological demands around 100 runs are managed effectively through strategic batting adjustments.
