ROGER FEDERER (Reloaded) - SUMMARY

Once again, we are analyzing this so particular tennis player, that season after season beats historical records. This report is the third delivery of Tennis Top 10 about Roger Federer. We inform to the interested and fans that we have data for statistical analysis and perfor-mance not only from Federer, but of all the players of the circuit that play of ATP World Tour 250 at least. For those who have not read my previous reports (2) about Roger Federer, here are the links:


• “Roger Federer in Statistics” - Report of 28/03/2012

• “Roger Federer in Statistics (Updated)” – Report of 24/09/2015


I have divided the report in three parts, in the first part I comment briefly about the performance that Roger has had in recent seasons, more precisely from the 2011 season to February 2018 and explained a little that what the General Performance Index is. In the second part (Annex I) and the third (Annex II), I present statistical tables and graphs respectively. The information in Annexes I and II is presented for all surfaces, hard, clay and grass.


GENERAL PERFORMANCE INDEX (GPI)

In recent years I have collected tournaments information from the professional tour by tons and I noted that it is not enough to evaluate a particular tennis player only just for his/her ATP ranking or the statistics such as they are published, this is very limited, as I will demonstrate as soon as possible, not always those who are at the top of the ranking, in the Top 10 for example, have the best performance. A player ranked 20th could have, and indeed has had, better performance than Roger Federer (ranking 2, at the end of 2017) for a given period, the 2017 season for example.

To evaluate the performance of a player I have made an index that I have called it General Performance Index (GPI). I explain the calculation methodology of this index in the report: "General Performance Index (GPI) of the 2017 Season - ATP Top 100" (December 11th, 2017). "The basic purpose of this index is to measure the performance of the players by evaluating certain statistical parameters and depending on the output, order it from highest to lowest to establish a performance ranking."

This performance ranking or GPI ranking does not necessarily have to coincide with the ranking published by the ATP.

The ATP orders the ranking of the players according to the number of points and the GPI ranking orders them according to the performance in aspects such as services, points won with the services, returns, break points, tiebreak, matches won, etc.

We are going to begin by briefly commenting on figure 1 and then move forward with the explanation of table 1.

The analysis covers the entire seasons from 2011 to 2017 and partially the 2018 season (Until the Rotterdam Open, February 2018).

The tournaments included are the ATP World Tour 250, 500, 1000, the Barclays ATP World Tour Finals, Nitto ATP Finals 2017. On the side of the ITF are included the Australian Open, Roland Garros, Wimbledon, US Open and the Davis Cup. Also, are included the statistics of the 2012 and 2016 Olympic Games and the Laver Cup 2017 (exhibition tournament).

Figure 1 shows the evolution in the ranking that Roger has had. Since 2002 he has always remained within the TOP 10 and only three years of this period he has ended outside the Top 3 in the seasons 2002 (6), 2013 (6) and as No. 16 in the 2016 season where he had to retire because of a knee injury in the middle of the season3. Federer has remained among the three (3) best players on the planet 13 of the last 16 seasons. In the current 2018 season he is as No. 1 of the Emirates ATP ranking. Five (5) years ended No. 1, six (6) years No. 2 and two (2) years (2011, 2015) as No. 3.

Regarding the performance of Federer in the period that we are analyzing his work tool, his racket, it had some modifications that have obviously contributed in some way to the rebirth of this athlete. We could simplify that between 2011 and 2018, this period is divided into five parts:

3 The last match of the 2016 season dates from July 8th, 2016 in the Wimbledon semifinals situation where he was defeated by Milos Raonic (CAN) in five sets 3-6,7-6 (3), 6-4, 5-7 and 3-6 in 3 hours and 24 minutes. 6

1) Wilson Six.One Tour BLX Racket (2010 - 2011). It was a hard racquet with a 90-inch head. Federer had begun to be overtaken in speed by his rivals, in the context of an increasingly aggressive tennis. He was attacked a lot on his backhand and in-hooked the balls quite often.

2) Wilson BLX Pro Staff Six.One 90 Racket (2012 - 2013). It was not exactly the Federer´s best time in his professional career with Paul Annacone as coach. That 2013 season Roger finished 6th in the ATP ranking. By Roger Federer´s standards it was a setback, maybe for another player it would be the glory to finish No.6 worldwide.

3) Wilson Prototype Racquet (January - June 2014). In this period Federer was experimenting with a prototype with a 97-inch head. He was needing a racquet that had more output power for the ball and more stability in the hits.

4) Wilson Pro Staff RF97 Racket (July 2014 - July 2016). Wilson Pro Staff RF97 Racket (July 2014 - July 2016). It was already ap-proaching to the goal to reach a racquet that get the standards that Roger was demanding.

5) Finally, the last black version of the Wilson Pro Staff RF97 arrived (July 2016 - present). Racket with 97-inch head. We have already seen what that Federer "Reloaded" has achieved since he returned at the beginning of the 2017 season.


Federer + Wilson Pro Staff RF97 + Ljubicic + Luthi = FEDERER RELOADED


Obviously, that everything achieved by Roger in recent months is not due exclusively to the racket, there were changes with respect to the duration of the points (they are shorter), always talking about percentages he improved the points won with service especially with the second, the return has remained stable in the last seasons analyzed, with respect to his backhand he has experienced a considerable improvement, especially with his running parallel shots that are already became a legend. Federer has that ability to reinvent and recharge himself with energy and achieve goals that are for very few people. Federer is an intelligent person and has known how to choose his coaches in a timely manner. This aspect, his intelligence, almost nobody has mentioned it, but Roger is very smart. Note that with Edberg he began to frequent more the area of the net and with Ljubicic he has improved his serve and the backhand. Roger had good serve, now it´s better. He plays near the bottom line and hits the ball practically when it is upping printing more speed to his game and suffocating his rivals. He moves like a dancer through the court with a wonderful synchronicity. The addition of improvements to his already excellent tennis of the past has made Federer a unique sporting phenomenon.

Roger has been very clever in handling his physique leaving more than one sports journalist with the stone between his teeth when they mention his age whenever they have occasion. Something similar happens with Serena and Venus Williams. Never mind about Roger´s age! We must enjoy him without restrictions about this stuff! Roger Federer has been commented by such journalists on the issue of age since he was 34/35 years old and since then he has already won 4 Grand Slams, 2 ATP World Tour Masters 1000, etc.
