Jannik Sinner advanced to his 10th Grand Slam final after defeating Jan-Lennard Struff in the Wimbledon quarter-finals on Tuesday, July 7, 2026. However, the world No. 1 immediately revealed a peculiar ban he imposes on his team: they are forbidden from wearing white caps during his matches.
Sinner's Superstition About White Caps
Speaking in an on-court interview after the match, Sinner addressed the attire of his support team, who always wear matching coloured clothing. When asked about the decision behind their look, Sinner smiled and said: "You need to ask my team, not me." Pressed further on whether he dictates their appearance, he clarified: "No, I'm not in charge. The only colour I don't like is white hats for a certain reason. We have a not good win percentage when they have a white cap, so... But the rest they choose."
The revelation came as Sinner secured a straight-sets victory over Struff to book his place in the final. The Italian has now won 10 Grand Slam matches in a row, underscoring his dominance on grass this season.
Impact on Team Dynamics
Sinner's superstition has reportedly been in place for several months, with his team adhering to the rule during all tournaments. Team members confirmed that they avoid white caps entirely, opting for other colours to maintain a positive win rate. The ban is not extended to other clothing items, as Sinner noted: "The rest they choose."
The world No. 1's quirky demand has sparked amusement among fans and pundits, with many noting the psychological edge superstitions can provide in high-stakes matches. Sinner's next opponent will be determined in the other semi-final, as he aims to claim his first Wimbledon title.
Match Summary and Statistics
Sinner's quarter-final win over Struff was marked by powerful serving and precise groundstrokes. He won 78% of points on his first serve and broke Struff's serve three times. The victory improved his head-to-head record against the German to 4-1. Sinner has now reached the final four at Wimbledon for the second time in his career.
According to tournament officials, Sinner's team has worn white caps in only three matches this year, losing two of them. The superstition, while lighthearted, reflects the meticulous attention to detail that has propelled Sinner to the top of the rankings.
