Jannik Sinner’s mother, Siglinde, captured the attention of tennis enthusiasts on August 13 when a photo of her playing tennis went viral online. The image showed the Italian player’s mother dressed in black athletic wear with white shoes, holding a racquet ready for action on a clay court, prompting many Coco Gauff tennis fan comparisons among followers.

Unexpected Tennis Talent Emerges from Sinner’s Mother

Although Jannik Sinner was born in 2001 to Hanspeter and Siglinde and initially gravitated toward skiing, he ultimately chose tennis, supported wholeheartedly by his parents. His family has always emphasized hard work and strong values, which Sinner credits for his development as an athlete. While his father still works as a chef, and his mother assists at their family-run hotel, Haus Sinner, their involvement in tennis had been minimal—until now.

Fans were surprised and delighted to see Siglinde engaging in the sport herself, praising her skills and enthusiasm. The excitement sparked playful comparisons, with some likening her to top players such as Aryna Sabalenka and Coco Gauff. Social media responses included witty and supportive remarks celebrating her unexpected prowess and potential future roles as Sinner’s doubles partner or coach.

“Jannik Sinner couldn’t close the match, so she took matters into her own hands… let’s go… WTA is shaking…cocolenka who?” asked a fan.

“Streets are saying she is jack draper’s new official doubles partner for the us open,” said another fan jokingly.

“She will be Sinner’s coach in Roland-Garros 2026,” wrote another.

“HIDE YOUR FAV, MAMA SINNER IS GOING WIN ROLAND GARROS,” a fan stated.

“No she’s learning to play because she fears this is the only way her diva of a son will willingly play mixed doubles,” wrote one.

Jannik Sinner Expresses Gratitude for Mother’s Support at Wimbledon

Last month, Siglinde made a special trip to London to watch Jannik Sinner compete in the Wimbledon final against Carlos Alcaraz. Her presence provided emotional support for the young Italian, who won his first Wimbledon trophy. Despite her nervousness, flying in the morning of the final to be there for her son meant a great deal to both.

Following Sinner’s victory, the pair shared a touching embrace, reflecting their close bond. In a post-match interview, Jannik highlighted the significance of having his mother in the stands, sharing how it motivated him throughout the match.

“My mom arrived in London the same morning just to see the final, this already meant a lot to me. She was excited to see her son play on Wimbledon’s Centre Court, I was delighted to see them in the box. Of course there was a lot of tension, my mother suffers a little, but it’s normal, she is a mother and parents care a lot about their children.”

Looking Ahead: Sinner’s Upcoming Tournaments and Future Prospects
