A month ago, Jannik Sinner became just the fifth man in ATP rankings history to reach 50 straight weeks in their first career stint at No. 1.
Now, he hits another milestone.
Today, Sinner kicks off his 54th consecutive week at No. 1, surpassing Novak Djokovic for fourth-longest first stint at the top spot.
Djokovic first rose to No. 1 on July 4th, 2011 after winning his first Wimbledon title and spent 53 straight weeks at the top spot before getting displaced by Roger Federer on July 9th, 2012.
Sinner first rose to the top spot on June 10th of last year.
Sinner isn’t in danger of losing his No. 1 status anytime soon, either. Not only is he currently 2,030 ranking points clear of No. 2-ranked Carlos Alcaraz, 10,880 to 8,850, but he could potentially build on that lead in the coming weeks—he’s defending 500 points this week in Halle, where he won the title last year, but he’s only defending 400 points at Wimbledon, where he fell in the quarterfinals last year (and where Alcaraz earned 2,000 points for winning the title last year).
In terms of longest stints at No. 1 in ATP rankings history, whether it’s their first stint or not, Sinner’s current run of 54 consecutive weeks ranks 13th, and it’ll move up a few spots following Wimbledon.
