Abstract

This study extends previous analyses of winning percentage since 2014 for the 30 MLB teams and whether these performance data could have been predicted by the teams’ analytics adoption. The study also includes stadium attendance as a secondary indicator of performance. Based on MLB teams’ 2014 analytics adoption as reported by ESPN, there are statistically significant differences in teams’ winning percentage, attendance percentage, and cumulative (multiple seasons combined) winning percentage when looking at performance data in the three subsequent years (2015-2017). The differences in winning percentage remain significant for multiple seasons, though with decreasing statistical strength. MLB teams should be aware that an immediate benefit from analytics adoption may not occur, but subsequent years may see stronger results. This aspect of analytics adoption is a critical aspect to analytics usage, and this potential lag effect should be considered when adopting new methods and techniques in any part of the organization.
