Jannik Sinner made a very complicated start at Wimbledon. The world number one advances past the first round, completing a three-hour and 32-minute marathon against an excellent Miomir Kecmanovic. The final score at the Championships is 4-6, 6-3, 6-7(6), 6-2, 6-3 in favor of the Italian, forced to execute a double comeback on Centre Court. The match begins uphill for the South Tyrolean, who, returning from an injury at Roland Garros, experiences an unexpected blackout at 4-4 in the first set, handing over the set to the Serbian. Sinner responds quickly in the second set (6-3), but the third set became a sports drama. At 2-2, Jannik slips and hits his hip and thigh, leading the crowd to panic. Despite the pain and an obvious blood stain on his right shoe, the champion declined a medical timeout and fought on, but lost the set to a strong Kecmanovic in the tiebreak, 8–6. With his back against the wall, the Italian showed the mentality of a true champion. In the fourth set, he controlled the service games, breaking the Serbian twice and quickly tied the match at 6-2. Sinner demonstrated his agility and serve precision in the fifth and decisive set, recording 31 aces in total. The key break came at 4-2, breaking Kecmanovic's final struggle before the final 6-3. After overcoming the fear of the falls and his opponent's incredible resilience, the Italian champion was already looking ahead to the second round, where he would face Portugal's Nuno Borges.
