The aim of this study is to identify differences in relation to performance indicators between winning and losing teams of Group A of Spanish Basketball Amateur League, in function of the type of game. The sample of the study is formed by 231 games (N = 462 cases) that were played during 2005/2006 season by teams of Group A along EBA League Regular Phase (Spanish Amateur Basketball). Variables of the study were performance indicators and secondary variables, such as ball possessions and offensive and defensive efficacy coefficients. Inferential analysis between winners and losers showed that there were significant differences in many performance indicators as well as efficacy coefficients of three type of game, increasing number of indicators that differentiate according as games become unbalanced. Relative to balanced games, 2 points failed shots, scored free shots, defensive rebounds, assists and personal fouls, as well as efficacy coefficients, are the ones that differentiate between winning and losing teams. In relation to unbalanced games, scored field shots, turnovers and blocked made must be added. For very unbalanced games almost all performance indicators, except steals, offensive rebounds and 3 points shot failed, differentiate winner from loser. It shows that there are a greater number of performance indicators on average that differentiate winners from losers teams compared to other professional leagues, because of that we can say that exists a higher heterogeneity between teams that participate in this kind of amateur leagues.
