The 2025 ATP season finally came to an end on Sunday at the year-end ATP Finals in Turin.

Jannik Sinner’s triumph over Carlos Alcaraz in front of a home crowd marked the last chapter in what has been an enthralling year of men’s tennis.

While Sinner and Alcaraz have dominated at the majority of tour-level events, other stars have come on leaps and bounds throughout their campaigns.

Felix Auger-Aliassime had his best season since his breakthrough in 2022 and reached a career high of fifth in the world, while Ben Shelton and Jack Draper added maiden ATP Masters titles to their names.

Meanwhile, the likes of Joao Fonseca and Learner Tien put together impressive first full years on the tour.

For three ATP stars, however, 2025 has certainly been a year to forget in their tennis careers.

1. Stefanos Tsitsipas

Though Stefanos Tsitsipas has had to deal with injury at times this season, the Greek star will not look back on the year as fondly as others.

Statistically, Tsitsipas endured his worst season on tour in eight years, with an overall win-loss record of 22-18, which totals a win percentage of 55%, his lowest since 2017.

Though he did manage to pick up a title at the Dubai Tennis Championships in February, the 27-year-old has recorded an incredibly disappointing run.

Tsitsipas did not make it past the second round at Grand Slams, and only reached the quarterfinals at one Masters event, which he achieved in Monte-Carlo.

Amid the poor results, the former world number three has made two coaching changes, having appointed Goran Ivanisevic for a brief spell, before parting ways with the Croatian after just two months of working together and rehiring his father.

Two years ago, Tsitsipas was contending for Grand Slam titles, and he will hope to return to the level he once reached in 2026.

2. Frances Tiafoe

While his American compatriots Taylor Fritz and Shelton continued to improve this year, Frances Tiafoe appears to have gone backwards.

Finishing the season with a record of 26 wins and 23 losses, Tiafoe saw his ATP ranking tumble to 30 in 2025, after starting the season 17th.

The US star, who reached the semifinals at Flushing Meadows in 2024, had his worst Grand Slam results since 2021.

Tiafoe managed to advance to the quarterfinals at Roland Garros, but suffered second-round exits at the Australian Open and Wimbledon, and bowed out in round three at the US Open.

• Australian Open – Lost to Fabian Marozsan in the second round
• Roland Garros – Lost to Lorenzo Musetti in the quarterfinals
• Wimbledon – Lost to Cameron Norrie in the second round
• US Open – Lost to Jan-Lennard Struff in the third round

He made just one final throughout the season, reaching the title bout at the Clay Court Championships in Houston, where he ultimately fell to countryman Jenson Brooksby.

Now that he has parted ways with his coach, David Witt, Tiafoe can start afresh in January and try to get back to the top ten once again.

3. Andrey Rublev

Andrey Rublev exited the world’s top ten this year for the first time since the 2022 ATP season.

After five straight years of making it to the quarterfinals of at least once major, the former world number five failed to reach the last eight at the biggest stages in 2025.

Rublev picked up a sole tour-level title during February in Doha, but since then, he has been a shell of his former self.

The Russian finished with a record of 34 wins and 25 losses, ending the year ranked 16th in the world.

For most players in the world, Rublev’s season would be a dream, but with the standards the 28-year-old has set for himself in the past, it has to go down as a disappointing 10 months.

The good news for Rublev is that he will have a chance to pick up plenty of points at the Australian Open in January, having lost in the first round this year to Fonseca.
