General Performance Index©
(GPI: General Performance Index): "It is an index that measures the performance that a tennis player has had in a given period of time." This index, not shown here, is used to make the "General Performance Ranking© or GPI Ranking© ".
In this report, we have the data for the sec-ond quarterly of the 2019 season corre-sponding to the performance of the 50 best players according to the GPI Ranking©. Dur-ing this period, the podium is made up of Jo-hanna Konta (GBR), Belinda Bencic (SUI) and Maria Sakkari (GRE), in positions 1, 2 and 3 respectively of the General Perfor-mance Ranking© (table 1).
The following tournaments, which corre-spond to the second quarterly (April, May and June), have been included for the deter-mination of the Top 50 of the General Per-formance Ranking©. The tournaments have been developed on all surfaces, hard, clay and grass (Wimbledon not included).

The rest of the players are shown in table 1, standing out in the Top 10 of the GPI Rank-ing©, Kiki Bertens (NED), Petra Martic (CRO), Marketa Vondrousova (CZE), Tamara Zidansek (SLO), Caroline Garcia (FRA), Ashleigh Barty (AUS) and Yulia Putintseva (KAZ), among others.
There are only 7 Top 10 of the WTA Rank-ing in the Top 50 of the GPI Ranking©. Ash-ley Barty (AUS), the current No. 1 in world tennis, despite having been crowned cham-pion in Roland Garros and in the Premier of Nature Valley Classic in Birmingham, get quarterfinals at the Mutua Madrid Open, has failed to be at the top of performance this second quarterly. Of course, we are talking about the No. 1 and her 9th place in the GPI Ranking© of this quarterly, for another player it could be the maximum. Anyway, Barty is among the Top 10 of the
GPI Ranking© this quarterly. What I have just said about Ashley Barty is not a critic, it is a simple observation, her performance has been good, although not as we expected. On the other hand, with respect to the performance of No. 2 of the tennis planet, the young Japanese Naomi Osaka, has surprised us a little, because this second quarterly she has been ranked 36th in the GPI Ranking©, this situation is notori-ous due to the few matches she has played in this period of time (3 months), she only played 13 matches, although she won 10/13 (Table 3).
The WTA Ranking that has been taken for this report is on July 1st, 2019.
