The unofficial
ELO ranking system places
Novak Djokovic as the best player on hard surfaces
for the year, ahead of
Carlos Alcaraz, and shows variations in the top-10.
The
ATP
Ranking has often been criticized for not being truly accurate in assessing the
top players. Despite efforts to improve it, the system considers results in
tournaments over the past 52 weeks and is often subject to criticism.
The ELO
ranking system appears as an alternative that uses new variables to determine
the list of the strongest players in the last year, and it often results in
several changes compared to the top-10 in the ATP Ranking. However, in many
cases, the titles and victories still align with the ranking.
If we look
at the titles, Djokovic and Medvedev both have 4 titles on hard courts this
year, but Djokovic can celebrate winning both the Australian Open and the US
Open on this surface. Then, Sinner and Fritz also have two titles on hard
courts this year.
The rest of
the players on the list have all won at least one title on hard courts this
year, with the exception of Andrey Rublev, who has not achieved this feat but
still holds the 6th place in the rankings.
However,
it's important to note that the ELO ranking system does not solely consider
titles or the quantity of wins but also factors in the quality of opponents
faced to generate a score.
“The
principle behind any Elo system is that each player’s rating is an estimate of
their strength, and each match (or tournament) allows us to update that
estimate. If a player wins, her rating goes up; if she loses, it goes down.”
The Elo ranking system, for example, removes Holger Rune, who is the world No. 4, from the top 10 for hard courts and includes Hubert Hurkacz, currently ranked 17th in the world.
Player | ELO Ranking | ATP Ranking |
Novak Djokovic | 1 | 1 |
Carlos Alcaraz | 2 | 2 |
Daniil Medvedev | 3 | 3 |
Jannik Sinner | 4 | 7 |
Taylor Fritz | 5 | 8 |
Andrey Rublev | 6 | 6 |
Alexander Zverev | 7 | 10 |
Alex De Minaur | 8 | 12 |
Stefanos Tsitsipas | 9 | 4 |
Hubert Hurckacz | 10 | 17 |
One of the
qualities of the Elo system is that the rating increases or decreases based on
the opponent against whom the match is played. For example, the system
considers that defeating Carlos Alcaraz (2nd) will have a greater impact on the
player's position than defeating Zverev (7th), and an even greater impact than
defeating Hurkacz (10th).
Conversely,
losing to Djokovic will have a relatively minor effect on the player's rating,
as Djokovic is considered the strongest player according to the system. The
impact on the rating increases progressively as the opponent's rating
decreases.
This applies
to the ATP Tour and especially Grand Slam tournaments, where some players
manage to advance to later rounds by facing lower-ranked opponents than their
peers.
For
instance, in this year's Wimbledon, Sinner reached the semifinals without
facing any player in the top 75, whereas in the same tournament, he defeated
two top-20 players. This situation is similar to Alcaraz, who also defeated two
players ranked within the top 25.
“There were
50 singles matches at the Davis Cup finals, and Elo picked the winner in 36 of
them, for an accuracy rating of 72%. The ATP rankings picked the winner (in the
sense that the higher-ranked player won the match) in 30 of them, for an
accuracy rating of 60%,” (about 2019 Davis Cup).
