The singles semifinals concluded Friday night at the 2025 US Open. Now that we’re down to two men and women in each singles draw, let’s take a look at the numbers that are currently moving the needle in Flushing Meadows.
1: Jannik Sinner and Carlos Alcaraz will battle for more than the 2025 US Open title on Sunday. The ATP’s No.1 ranking goes to the winner as well.
2: Semifinal comebacks. Thursday’s US Open women’s singles semifinals saw both players come from a set down to win for the first time since 1993.
2:56: The length of Amanda Anisimova's semifinal victory over Naomi Osaka, which is the second-longest US Open semifinal since 2000.
3: Number of consecutive Grand Slam finals played between Alcaraz and Sinner. After finals at Roland-Garros and Wimbledon earlier this year, world No. 1 Sinner and No. 2 Alcaraz are the first men’s duo to face each other in 3 Grand Slam finals in one season in the Open Era (first since Emerson vs Stolle in 1964).
4: Aryna Sabalenka will bid for her fourth major title on Saturday. The world No.1 has won three of the last five hard court Slams.
5: Sinner has become the fourth man to reach five consecutive Grand Slam finals in Open Era after Federer (10 in 2005-07, 8 in 2008- 10), Djokovic (6 in 2015-16, 5 in 2020-21) and Nadal (5 in 2011-12).
6: Sabalenka has reached the final at each of her last six hard court majors, compiling a record of 38-2 in that span.
7: Alcaraz reaches his seventh career Grand Slam final with his win over Novak Djokovic on Saturday. He has won five of his previous six.
8: Alcaraz and Sinner have combined to win the last eight majors. It’s the first time that two players have combined to win eight or more majors in succession since Federer and Nadal won eleven straight majors from 2005 Roland-Garros to the 2007 US Open.
9: Number of times that Anisimova and Sabalenka have met before, with Anisimova winning six of nine encounters.
Anisimova leads Sabalenka 3-2 at the majors, and the pair have split their two Grand Slam matches this year, with Sabalenka taking out the American at the French Open, and Anisimova returning the favor in the Wimbledon semifinals.
10: Djokovic, who fell to Alcaraz, 6-4, 7-6(4), 6-2, lost all ten sets he played in major semifinals this year.
15: Alcaraz and Sinner will square off for the 15th time in Sunday’s men’s singles final. The Spaniard holds the head-to-head edge of 9-5 in their previous 14 meetings.
18: Sets won by Alcaraz. He’s into a Grand Slam final without dropping a set for the first time.
23: Anisimova (23 years 358 days) is the youngest player to reach the Women’s Singles finals at Wimbledon and the US Open in a single season since Serena and Venus Williams in 2002.
26: Sabalenka (2023-25) is the first player to reach the Women’s Singles final at both the Australian and US Open in three consecutive years since Martina Hingis (1997-99).
27: Sinner’s hard court Grand Slam winning streak hits 27. His last loss at a hard court major came in the fourth round of the 2023 US Open to Alexander Zverev.
47: Years since a women’s semifinal had its first two sets decided by tiebreak at the US Open. Before Anisimova’s classic with Osaka on Thursday it had not happened since Pam Shriver defeated Martina Navratilova in the 1978 semis.
98: Percentage of service games held by Alcaraz, which leads all players. The Spaniard has dropped serve just twice in 84 service games.
100: If Sabalenka wins on Saturday, she will claim her 100th Grand Slam main draw win.
300: 24-year-old Sinner recorded his 300th career win on Friday against Felix Auger-Aliassime and became the youngest man in the Open Era to reach all 4 Grand Slam finals in one season.
