Carlos Alcaraz and Jannik Sinner have dominated the ATP Tour for the past two seasons, splitting the last eight Grand Slams between them.
The two men have not lost a tournament that they have both entered since Andrey Rublev won the Madrid Open in 2024.
On the women’s draw, Coco Gauff and Iga Swiatek have been less dominant but they have enjoyed a similar rivalry.
The pair, who are set to clash at the United Cup, are set to emulate Sinner and Alcaraz ahead of the Australian Open.

Coco Gauff and Iga Swiatek set for 16th meeting at the United Cup
Gauff and Swiatek have been leading their respective nations at the United Cup and the United States and Poland are set for a semi-final match at the event.
In a re-match of the 2024 United Cup final, Gauff and Swiatek’s meeting will be their 16th on the WTA Tour.
How long will it take for Coco Gauff to complete the career Grand Slam?
That will equal the amount of times that Sinner and Alcaraz have met, with their 16th meeting coming during the final of the ATP Finals.
Gauff and Swiatek are, without a doubt, the most prolific rivalry at the top end of the WTA Tour, which is even more remarkable considering their age.
Swiatek is just 24 years old and Gauff is only 21, which makes it even more impressive the amount of times they have met on the WTA Tour.
Coco Gauff’s record against Iga Swiatek
Gauff has struggled against Swiatek in their previous meetings, having only won four of their 15 meetings on tour.
However, recent history dictates that Gauff is beginning to understand exactly how to beat the Polish world number two.
What is your bold prediction for the 2026 tennis season?
Gauff has won the pair’s last three meetings, all of which came in 2024, at the Madrid Open, the United Cup, and the WTA Finals.
The American’s only other win against Swiatek came at the 2023 Cincinnati Open, when Gauff beat the Pole in three sets.
Their only two meetings at a Grand Slam have both come at Roland Garros, which went the way of Swiatek.
Swiatek has also picked up wins against Gauff in Rome, Miami, San Diego, Dubai, Beijing, and the WTA Finals.
