Performing in front of a crowd increases motivation.However, it also creates a psychological pressure, which may hinder performance, especially in precision tasks in decisive situations, such as assessment tests, job-related talks, or sports competitions. In this paper, I shed light on the effects of pressure on performance. Using the task of batting in baseball competitions involving Major League Baseball regular season games from 2015 to 2018, I find evidence of a negative causal effect of audience size on the probability of a successful bat for all players. The results are in line with the hypothesis of choking under pressure when performing skill-based tasks. However, contrary to what would be expected given the evidence in favor of a choking phenomenon, star batters do not choke but instead tend to excel when facing large audience. They also behave differently from nonstar batters when facing different audience compositions.
