There are several tactical variants that can be used by the serving and receiving teams before the serve is struck in tennis doubles. The goal is to analyse the frequency and efficiency of the tactical variants of the serving and receiving teams in doubles at the elite level. We analysed 1067 points in 18 doubles matches in professional men's top-level tennis tournaments. Next to the Classical formation, the I-formation was used in 46 % of points when players hit the first serve and in 41 % of cases when the point started with the second serve. Both formations had very equal efficiency, both after the first and second serve. The receiving team preferred a formation where both players were positioned at the baseline (53 %) when returning the first serve, but only in 18 % of points when they faced the second serve. The results summarize strategies and specific tactical variants in current game performance of male doubles at the top tennis level and the results can help to set a default set-up of training volumes of these game situations. The coaches can use the information and adjust the practice sessions according to the tactical demands of professional tennis.
