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 Rank-ing© or GPI Ranking© ".

The following tournaments of Grand Slams, which correspond to the 2019 sea-son, have
been included for the determination of the Top 50 of the General Performance Ranking©:

•    Australian Open – Grand Slam (hard).
•    Roland Garrós – Grand Slam (red clay).
•    Wimbledon – Grand Slam (grass).
•    US Open – Grand Slam (hard).

The WTA Ranking of the players, which has been considered for this report, is on September 16th, 2019.

Regard the 179 players, whom participated in these four Grand Slams and who com-pound the statistic sample that has been considered for the statistical calculations, only the 50 that have achieved the best performance in the mentioned tournaments are exposed (table 1).

We highlight, as usual, the podium of the 2019 season of the Grand Slams formed by, Serena Williams (USA), Ashley Barty (AUS) and Karolina Pliskova (CZE), in positions 1, 2 and 3 of the GPI Ranking©, respectively.

Other players highlighted in the TOP 10 of the GPI Ranking© are: Johanna Konta (GBR), Simona Halep (ROU), Elina Svito-lina (UKR), Naomi Osaka (JPN), Elise Mertens (BEL), Petra Martic (CRO) and Qiang Wang (CHN). See table 1.

The undisputed star regarding the perfor-mance in the Grand Slams of the 2019 season has been Serena Williams. Alt-hough Serena did not win any Grand Slam titles this season, she has obtained the best performance and regularity of the women´s circuit in the Grand Slams. Serena won the quarterfinals at the Australian Open, 3rd round at Roland Garros, runner-up at Wimbledon and the US Open, not bad. Serena Williams, like Federer, Nadal and Djokovic, belong to that extinction species, they are a super gifted with mindset that solve problems while they are competing.

Serena Williams has led all the GPI Rank-ing© in the different aspects analyzed. Serena, as usual, has stood out in the 1st and 2nd serves and has also stood out in the returns of the 1st and 2nd service of the rivals.
On the other hand, there is a group of players who are really excellent and who are struggling to belong to that select group called Top 10, Top 20, Top 100, the cusp of women´s world tennis excellence. Those players are the ones in table 1.

As an additional comment, I wish to mention the increasing improvement in the perfor-mance of China´s women´s tennis. In table 1 appears in the Top 10 of the GPI Rank-ing© the tennis player Qiang Wang and in position 15 of the same table 1 figure Shu-ai Zhang too. It seems to me that, in the coming seasons, it will be very common to see in the leading places of the WTA Ranking and in the GPI Ranking© the Chinese tennis players. Congratulations to those low-profile players that, little by little, they are moving inexorably towards the top of world women´s tennis.

Also, I have made an annex with tiebreaks, aces and double faults.
