Abstract

Background: One year after the Major League Baseball (MLB) pitch clock was implemented, position players saw decreased injury rates. The aim of this study was to see if injury rates in position players decreased two years after the implementation of the MLB pitch clock.

Methods: Injury data was collected for the 2021, 2022, 2023, and 2024 MLB seasons for position players using the fangraphs.com injury database. The incidence rate ratio was calculated to compare the injury rate for the 2024 season to each of the 2021, 2022, and 2023 seasons. A z-test for proportions was used to determine significance levels.

Results: Comparison of the 2024 season to both the 2022 and 2021 seasons found a statistically significant (P<0.05) decrease in the overall total incidence of injuries, upper extremity injuries, head and neck injuries, and lower extremity injuries. Comparison of the 2024 to the 2023 season also found a decrease in the incidence of injuries for the overall number of injuries (P=0.020) and head and neck injuries (P=0.424).

Conclusions: This study found a continued decrease in the overall incidence of injuries and a decrease in the incidence of injuries in multiple sub-categories at two-year follow-up since the implementation of the pitch clock. This continued decrease in injuries in position players may stem from a decrease in players' overall workloads over a season.

美国职业棒球大联盟投球钟：两年位置球员回顾性队列损伤分析。

背景：在美国职业棒球大联盟（MLB）投球时钟实施一年后，位置球员的受伤率下降了。本研究的目的是观察在MLB投球时钟实施两年后，位置球员的受伤率是否下降。方法：使用fangraphs.com伤病数据库收集2021、2022、2023和2024赛季MLB位置球员的伤病数据。发病率比的计算是为了比较2024赛季与2021、2022和2023赛季的伤病率。采用比例的z检验来确定显著性水平。结果：将2024赛季与2022赛季和2021赛季进行比较，发现具有统计学意义(p结论：本研究发现，自球场时钟实施以来，在两年的随访中，受伤的总体发生率持续下降，多个子类别的受伤发生率下降。位置球员伤病的持续减少可能源于球员在一个赛季中整体工作量的减少。
