Sinner needs to defend 3200 points before and during the US Open, while Alcaraz only has 60 points to protect.
At present, Sinner is ranked first in the ATP standings, with Alcaraz in second place, trailing Sinner by 3430 points. However, the numbers do not capture everything. During the North American hard court series, the battle for the world number one could become fierce, with a chance for the top spot to change.
Sinner's pressure to defend points is as high as 3200, while Alcaraz only needs to safeguard 60 points in comparison. From a net points perspective, this means that the day after the US Open, Sinner and Alcaraz will be almost evenly matched in their pursuit of the world number one. The player who performs better in the next two months is likely to take the top spot after this year's final Grand Slam event.
Last year, Alcaraz did not participate in the Canadian Masters and subsequently lost to Gael Monfils in the first round of the Cincinnati Masters. After that, he had a surprising second-round exit at the US Open, losing to Dutch player Van de Zandschulp, earning only 50 points in New York. Meanwhile, Sinner reached the quarterfinals in Canada and successfully won titles at both the Cincinnati Masters and the US Open.
It was during this period that Alcaraz's ranking points began to widen the gap between him and Sinner.
Sinner defeated Alcaraz in the Wimbledon final on Sunday, improving his ATP head-to-head record to 5 wins and 8 losses against him, having previously lost four consecutive matches. Now, Alcaraz can narrow the gap at the Toronto event (Canadian Open) and the Cincinnati event before heading to the US Open, where the honor of world number one may become the focal point for the first time this summer.
As the first Italian to reach world number one, Sinner has held the top spot for 58 consecutive weeks, marking the fourth-longest duration at number one in the history of the PIF ATP rankings. Alcaraz became the youngest world number one after winning the US Open in 2022, having held the top position for a total of 36 weeks in his career.
Record for the longest duration at world number one
After Wimbledon, Sinner's record this season stands at 26 wins and 3 losses, while Alcaraz's record is 48 wins and 6 losses.
