Evolution of team performance in One Day International cricket: an in-depth study of changing trends and effect sizes
研究了1987至2023年一日国际板球关键绩效指标的演变及其对比赛结果的影响，发现第一局得分稳定但高分增多，第二局投球效率和击球伙伴关系对胜负起关键作用。
This study presents a detailed statistical analysis of key performance indicators (PIs) in One Day International (ODI) cricket from 1987 to 2023, focusing on how these indicators have evolved and influenced match outcomes. This research is first of its kind employing statistical methods to understand how ODI cricket has evolved in a span of 37 years. We employed multivariate time series analysis using Mann-Kendall tests to detect trends in PIs and Cohen’s effect size analysis to examine their effect on winning the game. Our findings reveal that while first innings scores have remained relatively stable, exceptionally high scores have increased, reflecting a shift toward more aggressive batting strategies. The analysis highlights the critical role of first innings run rates and overs batted, with teams prioritizing quick scoring and maximizing resources. In the second innings, improvements in bowling efficiency and wicket-taking were found to play a decisive role in determining match outcomes. The study also reveals the crucial role of partnerships in successful run chases. By applying statistical methods, we offer insights into how teams can optimize their strategies to improve performance. Our research contributes to the broader understanding of how ODI cricket has evolved and provides practical guidance for teams and coaches.
