This study tests the uncertainty of outcome hypothesis for single games and playoff appearances in the Korean Professional Baseball League from 2007 to 2015. Our panel data analysis shows that the difference in winning percentages between two teams and playoff uncertainty based on games behind are important factors for increasing game attendance. This study supports the potential importance of analyzing daily game attendance of the literature on diverse sport leagues. It also presents implications for policymakers and league owners—which typically leverage teams as promotional instruments—on improving the self-sustainability of sport teams.
