Sinner set to pass Stefan Edberg’s weeks‑at‑No.1 mark with Alcaraz sidelined

Jannik Sinner is set to move past Stefan Edberg’s 72 weeks at world No. 1 after Carlos Alcaraz shut down the rest of his 2026 clay season. (atptour.com 1) (atptour.com 2) Alcaraz announced on April 24 that he will miss both the Internazionali BNL d’Italia in Rome and Roland Garros after tests on a wrist injury. ATP Tour said the Spaniard had already withdrawn from the Mutua Madrid Open on April 17. (atptour.com 1) (atptour.com 2) That matters in the rankings because Alcaraz is defending 1,000 points in Rome and 2,000 at Roland Garros, while ATP Tour listed him 390 points behind Sinner when he announced the shutdown. (atptour.com) Sinner returned to No. 1 on April 13 after beating Alcaraz in the Monte-Carlo final, a match ATP Tour said was also for the top ranking. He started that week on 67 career weeks at No. 1. (atptour.com 1) (atptour.com 2) Edberg’s benchmark is 72 total weeks at No. 1, which ATP Tour lists as 11th on the all-time men’s standings. Passing that mark would move Sinner ahead of one of the sport’s classic ranking milestones. (atptour.com) (atptour.com) The timing is straightforward. If Sinner keeps the top spot through the weekly rankings released on May 25, he would reach 73 total weeks and move beyond Edberg’s 72. (atptour.com) (atptour.com) Madrid is already underway, with the tournament scheduled from April 20 to May 3 at La Caja Mágica, so Alcaraz’s absence removes the home favorite from the biggest ATP event before Rome. (mutuamadridopen.com) (atptour.com) Alcaraz said on social media that doctors advised caution after the test results, and ATP Tour reported he wants to avoid an injury that could affect him long term. He owns a 22-3 record this season, including the Australian Open title and a trophy in Doha. (atptour.com) (atptour.com) For now, the clay swing’s ranking race has narrowed to Sinner holding No. 1 while his closest rival sits out Madrid, Rome and Roland Garros. If that holds for four more Mondays, Edberg’s 72-week total is next. (atptour.com) (atptour.com) (atptour.com)
