An imaginative Jannik Sinner suffered his second defeat of the year at the hands of Stefanos Tsitsipas, who advanced the two-time winner to the Monte Carlo Masters final 6-4, 3-6, 6-4.
With this victory, the Greek broke the nine-match winning streak of the Australian Open winner, who also holds titles this season from Rotterdam and Miami. Tsitsipas will face either top-seeded Novak Djokovic or Casper Ruud in the championship match on Sunday after their meeting in the second semifinal.
World No. 2 Sinner had a break of serve to start the final set, which saw him treated twice on his right knee by the trainer. However, he lost it in the eighth set, allowing Tsitsipas to even the score at four with four break points saved.
