Table 1 summarizes the performance of the Top 30 in the Grand Slams of the 2018 season. The players have been sorted based on the performance ranking or GPI ranking, starting with the best performance, in this case Angelique Kerber. The podium in the performance ranking of the 2018 season is formed of Angelique Kerber (1), Madison Keys (2) and Serena Williams (3).

In the calculation of the performance ranking the number of matches played has an important weighting. Anyway, as you can see in some particular cases, those who play more matches will not necessarily get a better performance ranking. In this article I have exposed only the "performance ranking" and not the "general performance index or GPI". As I have explained in previous articles, the Performance Index or General Performance Index serves to order them from highest to lowest and determine a "ranking". I thought that it is not necessary to expose the indexes. What really matters is to determine the performance ranking (independent of the WTA ranking) to know objectively where each player is positioned with respect to the others. Obviously, the ranking is calculated for all the players of the season, but for reasons of space I only expose the Top 30 and the Top 10.

Another aspect, already mentioned in previous articles, but it is relevant to mention it again, is the relationship that exists between the WTA ranking and the performance ranking or GPI ranking. These two rankings do not necessarily have to coincide, but in general there is a positive correlation (Depending on the degree of regularity of the players taken in the sample, the more regular, the more correlated). In Table 1 note that within the TOP 10 of the performance ranking are included 5 of the Top 10 of the WTA.

The real performance ranking or GPI ranking we can be calculated it at the end of the current season and at that time we will know which the best performances of 2018 will be taking as reference the totality of the players in the tournaments, WTA, Grand Slams and Fed Cup.
