      abstract = {This study estimates the effect of manager challenge in  Major League Baseball to test whether momentum exists in  sports. Despite much research over the last 30 years, the  existence of momentum in sports remains controversial.  Productivity of teams, measured by the number of runs in  the inning, is analyzed by using 1,193 replay reviews  during 2015-2019 regular season American League home games.  Using a difference-in-differences methodology, this study  fails to find statistically significant causal effect of  winning a manager challenge on the team’s productivity on  subsequent innings. However, there could still be a  shorter- or longer-term momentum as this study analyzes the  existence of a medium-term momentum that lasts for  subsequent two innings. The finding could be generalized to  other zero-sum settings where agents have option to  challenge.},
