Jannik Sinner is officially back on top.

The Italian tennis star reclaimed the No. 1 ATP ranking with a 7-6 (7-5), 6-3win over Carlos Alcaraz in the Monte-Carlo Masters final on Sunday. It is the fourth time the top ranking has exchanged hands between Sinner and Alcaraz over the past two years, with no other player coming close to breaking up the duopoly.

Sinner now sits at 13,350 points in the rankings, while Alcaraz is close behind him at 13,240. The next-closest is No. 3 Alexander Zverev with 5,595.

Sinner re-taking No. 1 also means he will take the lead in career weeks there in his rivalry with Alcaraz. The pair entered this week with 66 career weeks each at No. 1, but Sinner is now set to take a healthy lead there.

Jannik Sinner becoming No. 1 again was inevitable after the Sunshine Double

When Jannik Sinner was suspended three months last year over a positive doping test — which WADA accepted as being caused by a bizarre contamination involving a massage and over-the-counter spray — it didn’t stop him from competing in any Grand Slams. However, it did prevent him from playing four different ATP 1000 tournaments, and that has loomed over the rankings ever since.

In 2025, Sinner got zero rankings points from the Indian Wells Open, the Miami Open, the Monte-Carlo Masters and the Madrid Open. This year, he has 3,000 from those tournaments, with Madrid still to play.

He’s also made history in the process, becoming the first man in history to win the Sunshine Double of Indian Wells and Miami without dropping a set.

Alcaraz, meanwhile, had 1,410 points to defend from those tournaments, though he also skipped Madrid last year. So as soon as Sinner got 2,000 points from the Sunshine Double, it was hard to see him not doing well enough to take No. 1.

Alcaraz was well aware of that, admitting “I’m going to lose No. 1 of the world. I don’t know if it’s going to be in this tournament or the next one” earlier in the Monte Carlo tournament. The road doesn’t get much better for him for the rest of clay season, as he has another 3,330 points to defend at Barcelona, Rome and the French Open while Sinner has only 1,950.

It will get interesting again once the rankings reach the points from Wimbledon, which Sinner won last year and therefore has to defend, but for now it’s advantage Sinner.
