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, the 2019 season in this case, these indexes (not shown here) are sorted from the highest to the lowest and a 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 already mentioned in other articles, the ATP 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 young Russian Daniil Med-vedev (RUS), making him the No. 1 in the General Performance Ranking© or GPI Ranking© of the 2019 season. The GPI Ranking© podium is completed by Stefanos Tsitsipas (GRE) and Novak Djokovic (SRB) (Table 2, p.10). Other players highlighted in the GPI Ranking© have been Rafael Nadal (ESP), Roger Federer (SUI), Dominic Thiem (AUT), Alexander Zverev (GER), Matteo Berrettini (ITA), Diego Schwartzman (ARG) and the young Canadian Denis Shapovalov (CAN) whom complete the Top 10 of the GPI Ranking©.

The following categories of tournament, which correspond to the 2019 season, have been included for the determination of the Top 150 of the General Performance Ranking© or GPI Ranking©: The tournaments have been devel-oped on all surfaces, hard, clay and grass (In the section of Annexes the 150 players with better performance in each surface can be observed).

• Grand Slams: Australian Open, Roland Garros, Wimbledon, US Open.
• Davis Cup.
• ATP 250, 500.
• ATP Masters 1000.
• Next Gen ATP Finals.
• Nitto ATP Finals.
• Laver Cup (Unofficial and no points competition tournament for the ATP Ranking).

The ATP Ranking of the players, which has been considered for this report, is on Nov 25th, 2019.
Table 1 shows the variations in the ATP Ranking and GPI Ranking© of the 150 best performing players in the 2019 season. In the Top 10 of the GPI Ranking© we observe that Matteo Berrettini has been the player that most has advanced (58 places) compared to the 2018 season. Other players who have had a great performance and who have advanced in the GPI Ranking© regard the previous season are:

• Juan I. Londero (ARG): 316 places ↑
• Miomir Kecmanovic (SRB): 231 places ↑
• Christian Garin (CHI): 223 places ↑
• Reilly Opelka (USA): 163 places ↑
• Jo-Wilfried Tsonga (FRA): 107 places ↑
• Jordan Thompson (AUS): 101 places ↑

For the rest of players, see table 1, p 6.

Returning to the main protagonists of this 2019 season, Daniil Medvedev has been the most outstanding player in terms of performance, seconded by Stefanos Tsitsipas who has had a fantastic year crowned with his recent triumph over Dominic Thiem in the Nitto ATP Finals at London. In the Top 10 of the GPI Ranking© we observe that there are 5 young players (Medvedev, Tsitsipas, Zverev, Berrettini and Shapovalov), 2 mid-career (Thiem and Schwartzman) and three veter-ans (Big 3). 8 players of this Top 10 of the GPI Ranking© were in the Top 20 of the ATP Ranking of the 2018 season, this denotes a regularity in the most outstanding players. We are facing a generational transition where young tennis players are already gradually imposing. Another young player who is approaching the doors, both of the Top 10 of the ATP Ranking and the GPI Ranking©, is the Aussie Alex De Minaur, who will surely be one of the leading players in the coming seasons. Felix Auger-Aliassime from Canada is an-other player who seems to have a bright future, at least that is what he reflects, we will see in the coming seasons if we are right.

In table 4, it can be seen that the Big 3 comfortably surpasses the rest in the relation of won matches/played matches. Rafael Nadal, Roger Federer and Novak Djokovic. The Big 3 is always present in the big statistics. These three players deserve a separate article because of the exceptional performance and regularity throughout the seasons. This article is complemented by another one that we will publish later to have a big picture of the performance of players during the 2019 season.

We invite the specialized readers in tennis to analyze the tables of this report because they are really interesting and express the truth performance of the players in this 2019 season.
