Jannik Sinner and Carlos Alcaraz were the only two players to hold the world No. 1 Spot in 2025.

The 2025 ATP season ended with statistical clarity rarely seen in today’s era: 24, and Carlos Alcaraz, 22, and Carlos Alcaraz, 22, took the place of No. 1 edge of PIF atp at any time.
With both players under the age of 25 and sharing four majors between them, the season stands as a clear sign of a new phase in the ATP No. 1 Club. Their year-round control of the top 2025 spots is among the 1st 2 seasons in ATP history.
That difference becomes clear in the context of the past decades. Since the beginning of the PIF ATP rankings in 1973, a small number of seasons have given all the No. 1, under the age of 25, with 2025 entering alongside some of the sports that make up sports handovers.
ATP Tour Seasons in which all No. 1 players were under the age of 25 (since 1973)
| A year | Players (age) |
| 1975 | Connectors (23) |
| In 1976 | Connectors (24) |
| 1980 | Borg (24), Mcenroe (21) |
| In 1984 | Lendl (21), Mcenroe (24) |
| 1993 | Courier (23), Sampras (22) |
| 1994 | SAMPRAS (23) |
| 1995 | Agassi (25), SAMPRAS (24) |
| 2002 | Hewitt (21) |
| 2004 | Federer (23), Roddick (21) |
| 2005 | Federer (24) |
| 2025 | Sinner (24), Alcaraz (22) |
* The ages listed represent the oldest age each player reached when they held the No. 1 place at that time
What links these seasons together is that they highlight transitional periods – periods in which emerging champions take command of the sport earlier than expected. The 2025 season is very much on that bullet list, echo
A comparison with the three major periods adds an important perspective. Roger Federer, Rafael Nadal, and Novak Djokovic have produced one of the Lexus Atp Head2head Trilogies in tennis history, but their opponents are rarely at No. 1 when they are very young.
Federer holds the record for most consecutive weeks at No. 1 (237 between 2004-08), Nadal finally started out in 22, and Djolovic took 22 fights, and Djolovic took 2019 fights, but last, two fights of No. 1 among them did not arrive until the age of 25.
That’s what sets 2025 apart. Having two big hitters competing for No. 1 universe in 22 and 24 years is statistically and historically rare. The last time the couple shared this little control at the conference was more than two decades ago in 2004, when Federer at the age of 23 and Andy Roddick were controlled.
Rivals like soni-alcaraz have historically signed Pivotal shifts in games. Borg and McEnroe described the early 1980s as the most difficult battles that had decided the No.
