World No. 1 Jannik Sinner Extends 25-Match Streak, Powers into Madrid Open 2026 Quarter-Finals

Italian ace Jannik Sinner has rolled his red-hot form straight into the Madrid Open, stretching his unbeaten run to 19 matches and moving three wins away from an unprecedented sweep of the season’s first four ATP Masters 1000 events. The 24-year-old arrived in the Spanish capital already owning the Indian Wells–Miami “Sunshine Double” and a maiden Monte-Carlo Masters crown, a trio of clay-and-hard-court triumphs that propelled him past Carlos Alcaraz to world No. 1 and made him only the second man after Novak Djokovic in 2015 to capture those three titles in the same campaign. Many pundits wondered whether the heavy schedule would force Sinner to rest this week, but the Italian dismissed the idea. “I woke up quite good body-wise. I was like, why not? So we go here, we try,” he told Tennis Channel after routine wins over Benjamin Bonzi and Danish teenager Elmer Moller in his opening rounds. Victory in Madrid would hand Sinner a fourth straight Masters trophy—something no player, not even Djokovic, Rafael Nadal or Roger Federer, has achieved. It would also extend his lead atop the Pepperstone ATP Rankings heading into Rome and, crucially, Roland Garros, where the fast-improving clay game he displayed in Monaco has installed him as an early favourite. Sinner’s surge has coincided with injury trouble for chief rival Alcaraz, who withdrew from both Roland Garros and the Italian Open with a right-wrist injury, leaving the tour temporarily without its marquee rivalry and clearing the path for the Italian to tighten his grip on the No. 1 spot. Yet the South Tyrolean insists he is guarding against burnout: “When I feel like it’s getting too much for the body, I’m not scared to say no… but at the moment, I feel quite good,” he said. Statistically, Sinner has already banked 4,000 ranking points since March and is striking at a tour-leading 93 per cent win rate in 2026. His serve—once a vulnerability—has produced 77 aces against just 13 double faults during the streak, while his trademark inside-out forehand is averaging a blistering 135 km/h according to Hawk-Eye data released by the ATP. Next up in Madrid, Sinner faces explosive Frenchman Arthur Fils, who joked “don’t even mention” the winning streak when asked how to stop the Italian juggernaut. Should Sinner keep marching, a potential semi-final meeting with big-serving Daniil Medvedev beckons before Sunday’s championship match under the Caja Mágica roof. With history on the line and Paris looming, the message from the game’s newest superstar is clear: the tank is still full, and the records are there for the taking.
