Jannik Sinner’s brother Mark was adopted by the Sinner family when he was 9 months old.
World No. 1 Jannik Sinner won his first Wimbledon title in a hard-fought battle with two-time reigning champion Carlos Alcaraz.
It was a close contest throughout, but Sinner gained the edge late to secure a 4-6, 6-4, 6-4, 6-4 win.
After the match, Sinner climbed into the stands to embrace loved ones and his team, whom he later credited for helping propel him to the victory.
In on-court remarks, a smiling Alcaraz congratulated Sinner and said he’ll “absolutely” be back on Centre Court for another Wimbledon final in the future.
The matchup between two of the game’s brightest young stars once again lived up to the hype.
It was a rematch of last month’s French Open final, which many consider among the greatest matches in the sport’s history.
Jannik Sinner Poked Fun At His Brother, Mark, During His Acceptance Speech After Becoming The Wimbledon Champion
Jannik Sinner grew up with his brother Mark Sinner, who was born in Russia in 1998 and was adopted by Jannik’s parents when he was 9 months old.
Mark is a massive fan of Formula One racing.
As per the source, Mark is currently working as a trainer for the fire brigade in South Tyrol, near Austria.
During one of the interviews in 2023, Mark said that his relationship with Jannik is normal, like that of most brothers. He added,
“We played tennis – we tried at least. For a few years, I managed to keep up with him. Then he took off and it was impossible to exchange shots.”

In 2025, after Jannik’s glorious triumph at the Australian Open, where he retained his crown, he was open in his admissions. He said that having Mark was the best part of his victory.
He added,
“Nobody knows me better than him. For me, he is an important person. I call him, I confide in him, I know that I can tell him everything and he understands me.”

Recently, Jannik poked fun at his brother during his acceptance speech after winning the Wimbledon championship.
Jannik remained on Centre Court afterwards to partake in the traditional trophy ceremony, with Alcaraz the first to speak.
Then the 2025 men’s singles champion took to the microphone for a speech where he praised his opponent for a fantastic tournament.
Sinner then humorously aimed at his brother Mark for attending the final on a weekend when he wasn’t preoccupied elsewhere.
He explained,
“It’s so special. Seeing my parents here, my brother, my whole team, it’s amazing,” “Actually, a special thanks to my brother because there is no Formula 1 race this weekend, that’s why he’s here!”
