Tennis fans have a big reason to cheer!
Jannik Sinner from Italy is now the number one tennis player in the world. He took the top spot from Carlos Alcaraz after winning the Paris Masters. But wait — this fight for the top spot is not over yet!
A Close Fight Between Sinner and Alcaraz
Sinner and Alcaraz have been taking turns being number one all year.
A few weeks ago, Alcaraz was at the top for almost two months. Then, Sinner took it back again.
Right now, it’s super close!
- Jannik Sinner: 11,500 points
- Carlos Alcaraz: 11,250 points
That’s only a 250-point difference — almost like a photo finish in a race!

A Change Coming Next Week
Here’s where things get interesting.
Next Monday, Alcaraz will become number one again! Why? Because the ATP rankings remove points from last year.
Sinner will lose 1,500 points from his 2024 ATP Finals win.
Alcaraz will lose only 200 points from last year’s record.
So next week, the points will look like this:
- Alcaraz: 11,050 points
- Sinner: 10,000 points
This means the fight for the top spot is still wide open!
The Final Battle in Turin
The next big event is the ATP Finals in Turin, Italy.
This special tournament will decide who ends the year as the world number one. It starts this Sunday, and both Sinner and Alcaraz are ready for action.
Both of them have been amazing in 2025:
- Sinner won the Australian Open and Wimbledon.
- Alcaraz won the French Open and the US Open.
They even played against each other in three finals this year!
No one else is close to their level right now. Alexander Zverev, who is third, is more than 5,000 points behind.

What’s Next for Sinner and Alcaraz?
Now, everything depends on the ATP Finals:
- If Sinner wins the tournament and Alcaraz doesn’t reach the final, Sinner can be number one again.
- But if Alcaraz wins three matches, he’ll finish the year as number one!
Tennis fans around the world are waiting to see who wins this exciting battle — Sinner or Alcaraz. One thing is sure: it’s going to be a thrilling end to the tennis season!
Summary:
- Jannik Sinner is currently world number one.
- Carlos Alcaraz is very close behind.
- The ATP Finals in Turin will decide who stays on top.
- Both stars have won two Grand Slams each this year.
- The world is watching to see who ends 2025 as the true champion!
