In this paper we analyse tiebreak results from some tennis players in order to investigate whether we are able to identify a non-aleatory distribution of the points in this crucial moment of the game. We compared the observed results with a binomial distribution considering that the probabilities of winning or losing a point are equal. Using a χ 2 test we found that, excepting some players, the greatest part of the results agrees with our hypothesis that the points in tiebreaks are merely aleatory. Keywords: Sports, χ 2 Test, Binomial Distribution.Neste artigo, analisamos os resultados de "tiebreak" de alguns tenistas com o objetivo de investigar sé e possível identificarmos uma distribuição não aleatória dos pontos nesse momento crucial do jogo. Nós comparamos os resultados observados com uma distribuição binomial considerando que as probabilidades de ganhar ou perder um ponto são iguais. Usando um teste χ 2 percebemos que, com exceção de alguns tenistas, a maior parte dos resultados está de acordo com nossa hipótese de que os pontos em "tiebreaks" são apenas aleatórios.
