Jannik Sinner has advanced to the quarterfinals of the Monte Carlo Masters, securing a hard-fought victory over Tomas Machac. While the result—6-1, 6-7 (3), 6-3—keeps the world No. 2 on track for a title in the principality, the match revealed a rare flicker of vulnerability in a season that has otherwise been defined by near-total dominance.
The win ensures Sinner remains a primary contender in the ATP Tour clay-court swing, but it too signaled the end of a historic run. With the loss of the second set, Sinner’s streak of 37 consecutive sets won in Masters 1000 events came to a halt. Though the record is formidable, the interruption provides a glimpse into the physical and mental toll of a grueling calendar that has seen the Italian star surge to the top of the game.
Coming into the match, Sinner carried the momentum of the “Sunshine Double,” having conquered both Indian Wells and Miami in March. After a clinical opening round where he dismantled Ugo Humbert 6-3, 6-0, expectations were high for a routine victory over the Czech Machac, currently ranked No. 53 in the world. However, the contest proved to be more of a physical battle than a tactical masterclass.
A dominant start and a sudden dip
The match began as a showcase of Sinner’s current form. Despite a few early errors, the Italian quickly seized control, applying relentless pressure on Machac’s service games. A precise inside-out forehand secured an early break, sparking a collapse in the Czech’s game. Machac struggled to find any rhythm, committing 18 unforced errors in the opening frame, including a series of double faults that left him defenseless.
Sinner closed out the first set 6-1 in just 26 minutes, appearing completely untouchable. But as the match progressed into the second set, the momentum shifted violently. At 2-2, Sinner—who had been nearly perfect with his first serve—suffered a sudden and inexplicable lapse. A double fault followed by a string of errors in both the forehand and backhand departments allowed Machac to break through.
The dip appeared to be more than just a mental lapse; it looked like a physical crash. Sinner struggled with his movement and timing, falling behind 5-2. In a moment that highlighted the razor-thin margins of elite athletics, Sinner was seen taking an energy tablet during a changeover, suggesting a sudden drop in glucose or stamina that hampered his performance.
The struggle for recovery
Despite Sinner’s struggle, Machac was unable to capitalize on his opportunity to take the set. The world No. 53 appeared gripped by the pressure of the moment, committing seven unforced errors across the eighth and tenth games, including a wide backhand volley that handed the momentum back to the Italian. Sinner fought back to level the set at 5-5, forcing a tiebreak.
The tiebreak, typically a stronghold for Sinner—who holds a 7-1 record in such situations this season—did not go his way. Two forehands into the net and a final double fault sealed the set 7-6 (3) for Machac, officially ending Sinner’s historic set-winning streak.
The final set became a test of endurance. Sinner continued to struggle with his forehand, but he regained enough stability in his serve to keep the match within reach. At 3-2 in the third, the physical toll became evident as physiotherapists entered the court to treat both players. Sinner admitted to feeling “a bit weak,” requesting another energy tablet, while Machac required treatment for his left arm.
Despite the physical fatigue, Sinner’s superior baseline game eventually wore Machac down. He broke in the third game and maintained a steady lead, closing out the match 6-3 after two hours and one minute of play.

Looking ahead: The quarterfinal challenge
Reflecting on the match, Sinner was candid about his physical state. “In the second set I had an energy drop, the most important thing now is to recover well for the next match,” he stated, emphasizing the priority of recuperation over the disappointment of the lost set.
The path to the title now leads Sinner to a clash with Canada’s Felix Auger-Aliassime. The matchup is one Sinner has grown comfortable with, having won their last four encounters, though the first two meetings in their head-to-head history went in the Canadian’s favor. For Sinner, the goal will be to stabilize his energy levels and rediscover the clinical precision that defined his early season.

Sinner’s ability to win when not playing his “A-game” is often the hallmark of a champion. Whether this energy dip was a one-time anomaly or a sign of early-season burnout remains to be seen, but his resilience in the third set suggests he is still the man to beat on the red clay.
Sinner is scheduled to face Auger-Aliassime in the quarterfinals tomorrow. Stay tuned for live updates on his quest for a third consecutive Masters 1000 title.
