Jannik Sinner: A Beginner-Friendly Guide to the Tennis Superstar

The Big Wimbledon Showdown

One year after going head-to-head with famous tennis player Novak Djokovic at Wimbledon 2025, Jannik Sinner is getting ready to play on Centre Court again! This time, it’s a semi-final match against Djokovic, who has won Wimbledon seven times.

Last year, Sinner won their big semi-final match easily (winning every part of the match without letting Djokovic win one). In 2026, he’s looking super strong again — he has won his last four tournament rounds without losing a single round! Cheering him on from the sidelines will be his girlfriend, Laila Hasanovic.

Let’s learn everything about this power couple and Sinner’s amazing journey!

Who is Jannik Sinner?

Imagine a boy from Italy who loved hitting a ball over a net and grew up to be the absolute best in the world at it!

• Born: August 16, 2001
• Job: Professional tennis player from Italy
• Ranking: He is currently ranked as the world’s number one by the ATP (think of the ATP as the official scoreboard that decides who is the best tennis player on the planet).
• History Maker: He is the very first Italian player ever to reach that top spot!

Important Point: Being the world’s number one means out of everyone who plays tennis for a living, Jannik is currently the best!

What Big Trophies Has Sinner Won?

Sinner has a shelf full of shiny trophies! Here’s what he’s achieved:

• 19 singles titles on the ATP Tour (these are 19 different tournaments where he was the lone winner).
• 4 Major Championships (these are the four biggest, most important tennis tournaments in the world):
  1. 2024 Australian Open
  2. 2025 Australian Open
  3. 2024 US Open
  4. Wimbledon 2025
• 2024 ATP Finals (a special end-of-year tournament where only the top players compete).
• 4 Masters 1000 titles (these are almost as big as the Majors).
• He also helped his country win the 2023 and 2024 Davis Cup (a team competition where countries play against each other).

When Did Sinner Start Playing Tennis?

Jannik was a tennis prodigy (a fancy word for a super talented young person)! Here are the steps he took to become a star:

1. He started playing in professional men’s tennis events when he was just 16 years old.
2. By age 17, he was already winning multiple "Challenger" titles (these are like the minor leagues of pro tennis where players warm up for the big show).
3. In 2019, he won the "Newcomer of the Year" award (given to the best new player).
4. In 2021, he became the youngest-ever champion at the Washington Open (an "ATP 500" event, which is a medium-sized big deal!).

Has Sinner Beaten Djokovic Before?

Novak Djokovic is a legend, but Jannik has definitely beaten him!

• At the 2024 Australian Open, Sinner beat Djokovic (who was the world’s number one at the time) in the semi-final round. He then went on to win the whole tournament by beating Daniil Medvedev in a super long five-part final.
• At the 2025 Wimbledon semi-final, Sinner played a perfect game against Djokovic and won in three straight sets (meaning he won every single part of the match without letting Djokovic win one).

Important Point: Winning in "straight sets" is like winning every round of a board game without letting the other player score once!

Who is Sinner Dating?

Love is also a part of Jannik’s life! Here’s a simple timeline of his relationships:

• 2020 to 2024: He dated Italian model Maria Braccini.
• 2024 to May 2025: He dated Russian tennis player Anna Kalinskaya. He once said that dating while traveling the world is hard, but finding the right love is a beautiful thing. They broke up in May 2025.
• Now (2025/2026): He is dating Laila Hasanovic, a Danish model and fashion influencer. She created her own self-tanning brand called NRD55. Fun fact: she used to date F1 race car driver Mick Schumacher (they split in early 2025)!

How did we find out about Laila and Jannik?

1. Fans noticed her photo on his phone lock screen during the 2025 US Open.
2. He officially confirmed they were a couple during his winning speech at the Vienna Open in October 2025, thanking his "girlfriend" for supporting him.

Sinner’s Scandals: What Happened?

Even stars face tricky situations. Here’s what happened with Jannik:

• In August 2024, an independent group announced that Sinner had accidentally tested positive for a banned substance (a drug players aren’t allowed to use because it might give unfair help) called clostebol back in March 2024 (in two separate tests).
• Jannik explained that the drug got onto his skin because his physiotherapist (the person who gives him muscle rubs) used a cream with it. The tribunal (a group of judges) said Jannik did nothing wrong on purpose.
• However, he had to give back the prize money and ranking points he earned at the Indian Wells tournament.
• In early 2025, the World Anti-Doping Agency (the global group that stops cheating in sports) disagreed with the first decision. They made a deal with Jannik that led to him sitting out of tennis for three months.

Callout: Even though he didn’t mean to, rules are rules! Jannik had to serve a 3-month "time-out" from professional tennis.

How Much Money Has Sinner Won?

Playing tennis at this level pays very well!

• In 2024 (his best year), he took home $19,735,703 in prize money.
• In 2025, he won $19,120,641.

That’s a lot of ice cream money!
