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© ".

This index considers, for its calculation, a number of aspects such as the number of played matches and won, the serves, the points won with the serves, the returns, the break points (saved and won) and the tiebreaks. Once the indexes are calculated for a given period of time, i.e. the 2020 season in this case, these indexes (not shown here) are sorted from the highest to the lowest and a performance ranking is established. This ranking is the General Performance Ranking© or GPI Ranking©, which is used to order players by performance in the analyzed season. As it already mentioned in other articles, the WTA Ranking must not necessarily coincide with the General Performance Ranking©, in fact, this rarely happens. This General Performance Ranking© is very useful because it allows analyzing and quantifying the performance of an athlete in relation to the other players over a period of time.

The best performance of the season has been achieved by the Belgian Elise Mertens (BEL), making her the No. 1 in the General Performance Ranking© or GPI Ranking© of the 2020 season. The GPI Ranking© podium is completed by Elena Rybakina (KAZ) and Aryna Sabalenka (BLR) (Table 2, p.9).

Other players highlighted in the GPI Ranking© have been Anett Kontaveit (EST), Sofia Kenin (USA), Garbiñe Muguruza (ESP), Maria Sakkari (GRE), Elina Svito-lina (UKR), Ons Jabeur (TUN) and Ekate-rina Alexandrova (RUS) whom complete the Top 10 of the GPI Ranking©.

The following categories of tournament, which correspond to the 2020 season, have been included for the determination of the Top 150 of the General Performance Ranking© or GPI Ranking©: The tourna-ments have been developed this year only on hard and clay surfaces.

•    Grand Slams: Australian Open, Ro-land Garros, US Open.
•    Fed Cup.
•    WTA International.
•    WTA Premier.
•    WTA Premier 5
•    WTA 125K Series.

The WTA Ranking of the players, which has been considered for this report, is on Nov 23rd, 2020.

Table 1 shows the variations in the WTA Ranking and GPI Ranking© of the 150 best performing players in the 2020 season. In the Top 10 of the GPI Ranking© we observe that Elena Rybakina, Anett Kontaveit, Garbiñe Muguruza y Ons Jabeur have been the players who more have advanced (54, 39, 51 and 65 positions, respectively) with respect to the 2019 sea-son. Other players who have had a great performance and who have advanced in the GPI Ranking© over the previous season are:

•    Jennifer Brady (USA): 39 places ↑
•    Victoria Azarenka (BLR): 35 places ↑
•    Serena Williams (USA): 47 places ↑
•    Jessica Pegula (RUS): 60 places ↑
•    Jil TEichmann (SUI): 57 places ↑
•    Camila Giorgi (ITA): 56 places ↑

For the rest of players, see table 1, p. 5.

This season we have only 4 players from the Top 10 of the WTA Ranking in the Top 20 of the GPI Ranking©. It is evident, that this result is due to the worldwide pandemic known for all of us. We hope so in the 2021 season, these results could be reversed, since it is assumed that the players whom afford the highest WTA Rank-ings should be the ones with the most prominent presence in our General Performance Ranking© or GPI Ranking©.
