As Jannik Sinner seeks redemption at Wimbledon following a tough loss at the French Open, he will look to his player’s box for support. The composition of that support team, however, has seen dramatic shifts over the past year.
Most recently, Sinner dismissed fitness coach Marco Panichi and physiotherapist Ulises Badio just before the start of the tournament. “Nothing seriously bad happened,” Sinner explained to reporters. “The timing obviously isn’t the best, but having done a lot of work before, it won’t affect this Grand Slam a lot. I feel well physically and mentally and ready to compete.”
This follows an earlier shake-up in March, when Sinner parted ways with fitness coach Umberto Ferrara and physiotherapist Giacomo Naldi. Their departures came after Sinner tested positive for the banned steroid clostebol, though the International Tennis Integrity Agency (ITIA) later cleared him of any fault, ruling the contamination was inadvertent.
Despite the recent turnover, Sinner maintains confidence in his core circle. “I would describe my team as nice people, happy people,” he told the ATP Tour. “Everyone knows very well what he has to do. I feel good with them and lucky to have them.”
Here are the key figures who may be in Sinner’s player’s box at Wimbledon.
Coaches Simone Vagnozzi and Darren Cahill
Vagnozzi and Cahill are the cornerstones of Sinner’s coaching staff. Cahill, who joined the team in 2022, is set to retire at the end of this year, making Wimbledon one of their final Grand Slams together. Both coaches have praised Sinner’s composure. “I know he’s just 23 years of age, but sometimes it feels like he’s much older and wiser than what we are,” Cahill said at the Australian Open. Vagnozzi noted Sinner’s ability to thrive under duress, stating, “I think Jannik likes this situation, the pressure point, to be in a storm… in this moment, he [plays] the best tennis.”
His Mother, Siglinde Sinner
Sinner’s mother, Siglinde, is often a reluctant spectator due to nerves. During the Italian Open, she told Gazzetta that she rarely watches his full matches live, preferring to walk around until they are over. “My husband stayed; he never has any qualms,” she said. Her visibly tense reactions at the French Open subsequently went viral.
His Brother, Marc Sinner
Sinner’s older brother, Marc, may also be in attendance. Adopted by the Sinner family two years before Jannik was born, Marc works as a fire brigade instructor in South Tyrol, Italy. In an interview with Rome’s Il Messaggero, he described their bond as “like that of most brothers” and said they speak almost daily. “I am used to not seeing him at home, but when he returns it’s wonderful,” he shared.
His Father, Johann Sinner
Sinner’s father, Johann, runs a guest house with his wife, and his work commitments sometimes conflict with the tour. He notably missed the French Open final, where his son lost a close match to Carlos Alcaraz. “My dad was not here because he was working today,” Sinner said at Roland Garros. “Nothing of our success changes in the family.”
