Carlos Alcaraz ties Jannik Sinner with 66th career week at No. 1 on the ATP rankings

There’s a lot of movement on the rankings today after three ATP events and two WTA events last week, but the most significant storyline might involve no movement at all, as Carlos Alcaraz hits 66 career weeks at No. 1, tying main rival Jannik Sinner’s tally.

The two are now tied for 12th-most career weeks at the top spot in ATP rankings history, which dates back to August of 1973.

MOST CAREER WEEKS AS ATP NO. 1 (since 1973):

• 428: Novak Djokovic
• 310: Roger Federer
• 286: Pete Sampras
• 270: Ivan Lendl
• 268: Jimmy Connors
• 209: Rafael Nadal
• 170: John McEnroe
• 109: Bjorn Borg
• 101: Andre Agassi
• 80: Lleyton Hewitt
• 72: Stefan Edberg
• 66: Jannik Sinner, Carlos Alcaraz

And it gets even more interesting—Sinner has a chance at taking No. 1 back from Alcaraz in Monte Carlo this week. So which one of them will get their 67th career week at the top spot next week?

Alcaraz currently has 1,190 more ranking points than Sinner, 13,590 to 12,400, but with Alcaraz defending 1,000 points for winning Monte Carlo last year and Sinner defending nothing, they begin this week virtually separated by just 190 points, 12,590 to 12,400.

So how can Sinner pass Alcaraz?

First of all, Sinner needs to at least reach the semifinals in Monte Carlo just to have a chance—if he loses before the semifinals he’ll have no shot at No. 1, no matter how Alcaraz ends up doing.

And the deeper Alcaraz goes, the more Sinner will have to do.

If Alcaraz reaches the quarterfinals, Sinner will need to at least reach the final. And if the Spaniard reaches the final, the Italian will need to beat him in the final to take No. 1 back.

Meanwhile, further down the ATP rankings, last week’s three ATP champions all make moves: Tommy Paul rises from No. 21 to No. 18, his highest ranking since last October, after winning his first ATP clay-court title in Houston; Mariano Navone rises from No. 60 to No. 42, his first time in the Top 50 in over a year, after winning his first ATP title in Bucharest; and Rafael Jodar rises from No. 89 to a new high of No. 57 after his first ATP title in Marrakech.

The 19-year-old Jodar only just made his Top 100 debut a week ago, and now—after becoming just the sixth Spanish teenager in the Open Era to capture an ATP title—he’s nearly Top 50.

The runners-up from last week’s ATP events all make major moves, too: Roman Andres Burruchaga, who just made his Top 100 debut six weeks ago, jumps from No. 77 to a new career-high of No. 62 after reaching his first ATP final in Houston; Marco Trungelliti soars from No. 117 to No. 76, his Top 100 debut, after reaching his first ATP final in Marrakech; and 21-year-old Spaniard Daniel Merida almost cracks the Top 100 after reaching his first ATP final in Bucharest, jumping from No. 136 to No. 101.

Trungelliti, 36, has had a doubly historic few days with his run in Marrakech, not only becoming the oldest first-time ATP finalist in the Open Era, but now becoming the oldest player to make their Top 100 debut on the ATP rankings in over 50 years, since a 45-year-old Torben Ulrich cracked the elite in October of 1973.

Over on the WTA rankings, the most noteworthy move comes from Ukraine’s Yuliia Starodubtseva, who jumps from No. 89 to No. 53—surpassing her previous career-high of No. 63 and nearly cracking the Top 50—after her run to the final of Charleston, where she ultimately fell to the world No. 5, Jessica Pegula.

Starodubtseva had never even been to a WTA semifinal before, let alone a WTA final—let alone a WTA 500-level final.

And shout-out to Marie Bouzkova, who returns to her career-high of No. 24, which she originally reached in 2022 and 2023, after capturing her third WTA title in Bogota. Without much to defend until the summer hardcourt season, the Czech has a good shot at checking herself into the Top 20 over the next few months.
