Jannik Sinner and Alexander Zverev will face each other in the Monte Carlo Masters semi-final. Sinner reached the semi-finals by defeating Felix Auger-Aliassime 6-3 6-4, while Zverev advanced with a 7-5 6-7(3) 6-3 victory over Joao Fonseca. The outcome of their semi-final match remains unknown.
Jannik Sinner enters this clash in formidable form, having not lost a match since February 19. He recently became the first man to win Indian Wells and Miami back-to-back without dropping a set, though his record run of 37 straight sets won at Masters 1000 level ended against Tomas Machac. His current streak and recent achievements make him a formidable contender on any surface.
Carlos Alcaraz, the defending champion at the Monte Carlo Masters, continues his title defense with a quarter-final match against Alexander Bublik. Alcaraz began his campaign with a 6-1, 6-3 victory over Sebastian Baez in his opening match, and faced Tomas Martin Etcheverry in the round of 16, marking their first meeting on the ATP Tour. The outcome of his quarter-final against Bublik is yet to be determined.
The tournament has highlighted the intensifying rankings battle between Alcaraz and Sinner. Carlos Alcaraz believes he will lose the world No. 1 ranking soon.
Multiple reports indicate Jannik Sinner is likely to overtake Carlos Alcaraz in the rankings during the clay season, though the exact timing of when Sinner will claim the top spot is unclear. Alcaraz expressed surprise that Sinner played at the Monte Carlo Masters after competing in Indian Wells and Miami. Historically, Alcaraz has demonstrated superior success on clay compared to Sinner.
Alcaraz had a successful clay swing in 2025, winning the Monte Carlo Masters, Italian Open, and French Open, and finishing runner-up in Barcelona. In contrast, multiple reports note that Jannik Sinner has not won a big title on clay, raising questions about whether he will secure his first major clay trophy this season. The Monte Carlo Masters features a strong field, with seven of the top 10 ATP players competing.
Other notable results include Cameron Norrie's 6-2 4-6 7-6 (7-0) first-round victory over Miomir Kecmanovic. Jannik Sinner missed the Monte Carlo Masters last year due to a suspension, making his current run particularly notable. External perspectives on the dominance of Alcaraz and Sinner have emerged, with Alexander Bublik claiming that Carlos Alcaraz and Jannik Sinner are untouchable at Grand Slams.
Whether Alcaraz and Sinner will face each other at the Monte Carlo Masters this week depends on their respective progress through the draw.
