Jannik Sinner’s mom Siglinde Sinner has become a fan-favorite at his top matches due to her emotional reactions in the stands.
The mom doesn’t hide her feelings when her son is on the court, an emotional response deemed “relatable” in a Reddit thread.Her reactions on camera have gone viral several times.
The Tennis Letter called Jannik’s mother the “queen of reactions,” sharing photos of her at the French Open. The French Open match that Carlos Alcaraz won is considered one of the greatest tennis matches in the history of the sport, and one of the closest, so who can blame her for some nerves? Alcaraz won that match, but it was 4–6, 6–7, 6–4, 7–6, 7–6.

An Italian-language publication, Gazzetta, even reported how, at one match in May 2025, Sinner’s frazzled mom went for a walk outside. Siglinde is a former waitress, according to People, which noted that Sinner’s dad Johann (also called Hanspeter) Sinner is a chef. They met at a ski lodge.

“On the sidewalk, walking briskly, Jannik Sinner’s mother, Mrs. Siglinde, is spotted,” a translation of that article says, quoting the journalist as asking, “Ma’am, what are you doing here? Just a few minutes ago, you were shown several times on TV.”

“I left at the end of the first set. I’m taking a walk around here and waiting for the match to finish. I never watch Jannik’s matches live from start to finish—it rarely happens,” she added. “I prefer watching on TV. Only in Turin was I able to see the final live and a bit of the earlier rounds. My husband stayed; he has no problem with it.”

Sinner left the family home at age 13 to pursue tennis, according to People, but he has remained close to his mom and dad.
“I wish that everyone could have my parents because they always let me choose whatever I wanted to,” he said after winning the Australian Open, according to People.
He praised his parents for not putting pressure on him, thanking them and saying, “I wish that this freedom is possible for as many young kids as possible.”
