But this time, we are going to analyze those tennis players on the circuit ATP who have experienced a real boost compared to how they started 2025. Some names are unexpected, others are great promises, while some are veterans who have not yet said their last word in tennis.

These have been the biggest increases in the ATP 2025 ranking

Eliot Spizzirri

We start with an unusual and expected name that, however, has had a real boost this year. Still not making enough noise for the mainstream media spotlight, but with an increasingly frequent presence in important tournaments.

Eliot Spizzirri The 2025 season began number 228 in the ATP rankingfresh out of university, he made the jump to the ATP and little by little the feats began to arrive. It began with his first victory in a Masters 1000 in the Miami Open. And although he did not achieve another victory until the first round of the US Openhe was very regular on the circuit Challenger, which allowed him to gradually climb positions.

Thanks to his title at the Jingshan Challenger, he entered the top-100 of the ATP ranking and two good performances at the ATP in Brussels and Athens allowed him to close the year in the position. number 90. That is, an increase of 120 positions

Valentin Vacherot

Another unexpected tennis player, but one that the tennis world is already beginning to know very well. Valentin Vacherot was, without a doubt, the revelation of the year with its title in the Shanghai Masters 1000 after arriving from the previous phase. A milestone that took him from number 204 in the ATP ranking to number 40 in the world.

A rise of 164 positions that did not stop in China, but later, with its first round in the Basel ATP and the quarterfinals in the Paris Masters 1000served to close the year as 32nd ranked and with many options to be seeded in the Open the Australia when just four months ago he was competing in the Challenger circuit.

Joao Fonseca

The Brazilian promise did not disappoint. Although he had a moment of the season, from the beginning of the clay court tour to the US Open, where his game and the results did not match, with the exception of some sixteenths in Wimbledon y  Roland Garros. Even so, he was scratching more and more positions in the classification. But the beginning of the year was brilliant with the Canberra Challengerwinning his first match at the Australian Open and taking his first title ATP in Buenos Aires.

Then came the aforementioned journey, but with the start of the European indoor tour the best Fonseca was seen again, who won his second title of the season. While his round of 16 at the Paris Masters 1000 was his last match of a 2025 that began as the 145 in the world and it ends up being the 24th best racket.

Marin Cilic

The time has come for the old guard and whom no one had much hope of seeing again, especially due to their ages or injuries. It is the case of Marin Cilic. The 37-year-old Croatian did not have to prove anything to anyone after winning the US Open in 2014 and being number three in the world in 2018.

However, the passion for this sport was what continued to move him, something that not even injuries could stop. He started the year in 179th place and finished it within the top 100, specifically 75th place thanks to his two titles. Challenger (Girona y Nottingham)but above all because of the rush that it gave him to reach the sixteenths of Wimbledon.

Pablo Carreno

The Asturian tennis player was hampered by a serious shoulder injury that prevented him from recovering his high level shown for so many years. And this 2025 seemed decisive to see if he could compete again with the best tennis players. His ranking at the start of the season ranked him 196th in the world.

His season focused on the Challenger circuit, where he won the two tournaments in Tenerife, the one in Villena and reached the final in Olbia, while his best results on the ATP circuit were two Grand Slam second rounds at Roland Garros and the US Open. But enough to return to the top 100, as number 89, and face 2026 with the aim of entering the noble zone of the ranking.

Reilly Opelka

Although Opelka does not yet have veteran status, his recovery in the ranking is more than commendable. He stopped having a ranking when some discomfort in his hip in 2022 led to a tumor and the obligation to undergo surgery. And once his health was restored, he began his return.

Its ascension began in 2024, but in 2025 it has not slowed down, in fact, it has risen a total of 243 positions. It started as number 293 and ends up being 50th ranked. Thanks to its ending in Brisbane and their semi-finals in s’Hertogenbosch and its constant presence in the first rounds of major tournaments.

These have been the greatest progressions in the ATP in 2025, but let no one doubt that in 2026 we will experience more cases of this type. The unpredictability of tennis, one of its greatest strengths, helps to see all kinds of surprises.
