In this paper, we propose a mathematical approach to select line-ups of a baseball team using DEA(data envelopment analysis). We apply DEA to evaluate baseball players from the view point of uniqueness,and show the evaluation of players by means of DEA efficiency together with SI (scoring index),a measure of batting ability. Further, we evaluate line-ups by the number of the DEA effective players and the expected runs scored in a game by the line-up. We illustrate this method using the candidates of Japan national baseball team for the Beijing 2008 Olympic Games, and demonstrate how this approach may help to select the line-ups, by showing the concrete line-ups with the expected runs scored and the number of effective players.
