Jannik Sinner’s parents are a constant, reassuring presence in his player’s box. Throughout the 2026 Rome Masters 1000, his mother Siglinde and father Hanspeter have watched every single match side-by-side—from his opening round against Sebastian Ofner through demanding encounters with Alexei Popyrin, Andrea Pellegrino, and Andrey Rublev.
However, during a crucial phase in the second set of his latest match, spectators noticed Siglinde suddenly vacate her seat. While his father, his brother Mark, and his girlfriend Laila Hasanovic remained in the stands, her abrupt departure sparked immediate curiosity online.
The Reason Behind the Disappearance: “Too Much Stress”
The reason for her departure is a well-documented family tradition that Sinner himself opened up about just a day prior. During a special event at the tournament featuring Italian football icon Paolo Maldini, Sinner lightheartedly explained his mother’s courtside boundaries.
According to Sinner, Siglinde simply cannot cope with the heavy emotional toll of watching her son play when the stakes get too high or when things go wrong on the clay.
“If she sees that the match is calm, then she stays,” Sinner told Maldini. “Otherwise, she leaves; if the match gets complicated, she can’t make it to the end because she gets agitated and overwhelmed by stress.”
Physical Tensions Boil Over on the Clay
That exact threshold was crossed during the second set of today’s match. The departure coincided precisely with a dramatic shift in momentum on the Centrale court:

Siglinde Departs the Stands Due to Stress
As Sinner began displaying visible signs of physical discomfort and his opponent capitalized on the opening to mount a comeback, the atmospheric tension became too much for Siglinde to bear. Rather than letting the anxiety overwhelm her, she followed her usual routine and stepped away from the court, leaving the rest of the family to weather the storm.
