Every Next Gen ATP Finals Champion (2017-2025): Where Are They Now?

The Next Gen ATP Finals Champion Roll Call

Since 2017, the Next Gen ATP Finals has crowned 8 champions across 8 editions (the event was not held in 2020 due to COVID-19). What makes this tournament extraordinary is how accurately it has predicted future tennis stardom. Two champions became World No. 1. Several have won Grand Slam titles. Here's where every champion stands today.

2017: Hyeon Chung 🇰🇷

Age at win: 21 | Ranking at win: #51 | Defeated: Andrey Rublev

Chung burst onto the scene by winning the inaugural edition, then followed up with a stunning run to the Australian Open semifinals in January 2018, beating Novak Djokovic along the way. Tragically, chronic knee and back injuries derailed what looked like a breakthrough career. After multiple surgeries and attempted comebacks, Chung has spent years outside the top 300. Currently ranked around #363, he remains a cautionary tale of how injuries can rob tennis of its brightest talents.

2018: Stefanos Tsitsipas 🇬🇷

Age at win: 20 | Ranking at win: #15 | Defeated: Alex de Minaur

Tsitsipas used the Next Gen title as a springboard to superstardom. Just 11 months later, he won the ATP Finals in London — the senior version of the event — beating Roger Federer in the semifinals. He reached a career-high of World No. 3, won the Monte-Carlo Masters multiple times, and reached the 2021 French Open final (leading Djokovic 2 sets to 0 before falling in 5). Now a consistent top-10 presence, Tsitsipas remains one of the most talented players of his generation.

2019: Jannik Sinner 🇮🇹

Age at win: 18 | Ranking at win: #95 | Defeated: Alex de Minaur

The greatest success story in Next Gen history. Sinner was just 18 years old and ranked #95 when he won the 2019 title. Five years later, he is the World No. 1, has won 4 Grand Slam titles (2024 Australian Open, 2024 US Open, 2025 Australian Open, and 2025 Roland Garros), and has accumulated 16+ ATP titles. Sinner's rise from Next Gen champion to the top of the sport is the tournament's ultimate validation.

2021: Carlos Alcaraz 🇪🇸

Age at win: 18 | Ranking at win: #32 | Defeated: Sebastian Korda

If Sinner is the tournament's greatest success, Alcaraz isn't far behind. At 18, he dominated the 2021 field. By September 2022, he became the youngest World No. 1 in ATP history at age 19. He has since won 6 Grand Slam titles — including the 2022 US Open, 2023 Wimbledon, 2024 French Open, and 2024 Wimbledon back-to-back. Alcaraz and Sinner have formed the defining rivalry of modern tennis, and both are Next Gen champions.

2022: Brandon Nakashima 🇺🇸

Age at win: 21 | Ranking at win: #49 | Defeated: Jiri Lehecka

The American went undefeated through the tournament and peaked at #33 in the rankings. While he hasn't broken through to the very top tier, Nakashima remains a solid top-50 player and a regular on the ATP Tour. His consistent baseline game and mental toughness continue to serve him well.

2023: Hamad Medjedovic 🇷🇸

Age at win: 20 | Ranking at win: #110 | Defeated: Arthur Fils

The Serbian surprised many by claiming the 2023 title in Jeddah. He peaked at #69 but has since struggled with injuries and consistency. Medjedovic has shown flashes of the talent that won him the title but has yet to establish himself as a consistent top-50 player.

2024: Joao Fonseca 🇧🇷

Age at win: 18 | Ranking at win: #145 | Defeated: Learner Tien

The Brazilian teenager was the lowest-ranked champion in tournament history at #145. Fonseca has since exploded onto the scene in 2025, winning 2 ATP titles and climbing into the top 25. His powerful game and fearless mentality suggest he could follow the Sinner/Alcaraz trajectory.

2025: Learner Tien 🇺🇸

Age at win: 20 | Ranking at win: #28 | Defeated: Alexander Blockx

After reaching the 2024 final (losing to Fonseca), Tien returned to claim the 2025 crown. The American has been remarkable in 2025, recording 5 top-10 wins, winning an ATP title in Metz, and establishing himself in the top 30. He's the only player to reach two consecutive Next Gen finals and the only one to lose a final and come back to win the title.

The Verdict

The Next Gen ATP Finals' track record is extraordinary. Two champions became World No. 1. Two have combined for 10 Grand Slam titles. The tournament has proven itself as the most reliable predictor of future tennis greatness in the sport. Explore the full champions page for trajectory charts and head-to-head comparisons.

What the Champions Have in Common

Nine editions in, the eight Next Gen ATP Finals champions share less than you might expect. Two of them — Jannik Sinner and Carlos Alcaraz — reached World No. 1 within three years of their title. Two others, Hyeon Chung and Hamad Medjedovic, have yet to win an ATP Tour title. The tournament is a reliable talent filter, not a guarantee, and the difference between the two groups is where the real story sits.

The strongest common thread is age. Sinner (18), Alcaraz (18) and Joao Fonseca (18) all won the title at 18, and all three were ranked outside the top 30 when they did it. The champions who won at 20 or 21 — Chung, Stefanos Tsitsipas, Brandon Nakashima, Medjedovic and Learner Tien — were closer to the ceiling of the age bracket, which meant beating a field of younger players rather than older ones. Winning young, against opposition that was already ahead of you, has been the single best predictor of what came next.

The second thread is ranking momentum rather than ranking position. Fonseca arrived in Jeddah at No. 145 and left as champion; Alcaraz arrived at No. 32. What both had was a season of continuous climbing behind them. Tsitsipas, the highest-ranked champion in tournament history at No. 15, was already the most established player in his field and went on to a career-high of No. 3 — an excellent career, but the smallest relative jump of any winner.

Champions vs Runners-Up: The Trophy Matters Less Than You Think

The finalists list is arguably stronger than the champions list. Andrey Rublev lost the inaugural final to Chung and has spent years inside the top 10 with a Masters 1000 title. Alex de Minaur lost two finals, in 2018 and 2019, and became a top-10 fixture and Australia's Davis Cup leader. Jiri Lehecka, Sebastian Korda and Arthur Fils all lost finals and all reached the top 40 or better.

Then there is the group-stage list, which contains the most instructive name of all: Casper Ruud went 1-2 in Milan in 2019 and did not survive his group. Three years later he reached two Grand Slam finals in a single season, made the ATP Finals final in Turin, and climbed to World No. 2. Daniil Medvedev also exited in the group stage in 2017, then won the US Open and reached No. 1. If you were drafting careers from the 2017 and 2019 fields, the round-robin results would have actively misled you.

The lesson is that the event measures a specific skill set — first-strike tennis in short sets, with no let rule, no line judges, and a shot clock — under conditions no other tournament replicates. It rewards players who are already comfortable playing on their own terms at 18 or 19. Players who need a longer match to grind their way into control, which describes most clay-court specialists, are systematically underrated by the format.

Where Each Champion's Career Actually Turned

For Chung, the turn came within months. His run to the 2018 Australian Open semifinal, including a win over Novak Djokovic, was the peak of a career that chronic foot and back injuries steadily dismantled. He retired in 2023 having never won an ATP title — the only champion whose Milan trophy remains his biggest.

For Tsitsipas, the turn was 2019: the ATP Finals title in London and a first Grand Slam semifinal, converting Next Gen promise into elite status within twelve months.

For Sinner, the turn was the 2023-24 off-season. He had been a top-10 player for two years without a Grand Slam breakthrough; the serve rebuild and physical work that followed produced the Australian Open title and the No. 1 ranking.

For Alcaraz, the turn was the 2022 spring clay swing, when back-to-back Masters titles in Miami and Madrid — the latter including wins over Rafael Nadal and Djokovic in consecutive matches — announced that the ceiling was the very top.

For Nakashima, the turn was a plateau rather than a leap. He has been a solid, consistently ranked tour professional for several seasons, with a title and a Wimbledon fourth round, without pushing into the top 30.

For Medjedovic, the 2023 title in Jeddah remains his high point, with injuries and inconsistency keeping him in the 50-100 band.

For Fonseca and Tien, the turns are still in progress and are the reason to keep watching in 2026: both are inside the top 60, both have won ATP titles, and both are now beyond the age cut-off, competing with the players they used to watch.

What This Means for the 2026 Race to Italy

The 2026 edition returns the tournament to Italy after three years in Jeddah, and the race is being led by players whose profile fits the champion template closely: teenagers with a season of continuous ranking climb behind them. On the history above, the name to watch is not necessarily the highest-ranked qualifier but the youngest one arriving with momentum.
