Carlos Alcaraz clinches 2025 year-end No. 1 ranking after victory over Musetti at ATP Finals

Carlos Alcaraz has clinched the ATP's 2025 year-end No. 1 ranking after defeating Lorenzo Musetti at the ATP Finals on Thursday, 6-4, 6-1.

The Spaniard improved to 3-0 in his round-robin group with the win, and having started the week with 11,050 points—and with each round-robin win worth 200 points—he'll now have at least 11,650 ranking points after the tournament. That's now out of reach for Jannik Sinner, who would finish with 11,500 even with an undefeated title run in Turin.

Having also done it in 2022, Alcaraz is now the 11th player to finish two or more years at No. 1 in ATP rankings history, since they began in 1973.

He's also the first player born since 2000, or even since 1990, to do it.

• 8: Novak Djokovic [2011, 2012, 2014, 2015, 2018, 2020, 2021, 2023]
• 6: Pete Sampras [1993, 1994, 1995, 1996, 1997, 1998]

• 2: Stefan Edberg [1990, 1991]
• 2: Lleyton Hewitt [2001, 2002]
• 2: Carlos Alcaraz [2022, 2025]

And there's more.

At 22, Alcaraz is also the second-youngest man ever to finish two or more years at No. 1, after Lleyton Hewitt, who did it at 21.

YOUNGEST PLAYERS TO FINISH TWO OR MORE YEARS AS ATP NO. 1:

• 21 years & 8 months: Lleyton Hewitt [2002]
• 22 years & 6 months: Carlos Alcaraz [2025]
• 23 years & 3 months: Pete Sampras [1994]
• 23 years & 3 months: Jimmy Connors [1975]
• 23 years & 10 months: John McEnroe [1982]

As for the Big 3, Federer, Nadal and Djokovic were 24, 24 and 25, respectively, when they recorded their second year-end No. 1 finishes.

With the year-end No. 1 ranking on the line, Alcaraz played exceptionally on Thursday night, hitting 26 winners to 21 unforced errors, converting three of his five break point opportunities, and fighting off both of Musetti's break points during the match.

"This match was really important for me—playing for No. 1 wasn't easy for me at the beginning with the nerves," he said in his on-court interview. "I tried to handle that pressure and those nerves the best that I could, so I'm just really happy with the match, with the level that I played today, and obviously to end the year at No. 1."

Alcaraz finishes in first place in the Jimmy Connors round-robin group, and Alex de Minaur will finish in second place in the group after his victory over Taylor Fritz earlier in the day, advancing to the semifinals along with Alcaraz. Fritz and Musetti have been eliminated.

Sinner has already clinched first place in the Bjorn Borg round-robin group, meaning he'll play De Minaur in the semifinals. Meanwhile, in his semifinal, Alcaraz will face either Alexander Zverev or Felix Auger-Aliassime, who play for second place in their group on Friday night.
