Watch: Umpire mistakenly announces Stefanos Tsitsipas as winner after Ugo Humbert beats Greek in Shanghai Masters

Ugo Humbert's remarkable performance in the second round of the Rolex Shanghai Masters on Monday led to his victory over Stefanos Tsitsipas. However, there was a brief moment of confusion when the match umpire mistakenly announced Stefanos Tsitsipas as the winner.

The French tennis player won the match 6-4, 3-6, 7-5 to advance to the round of 16 at the ATP 1000 tournament. This victory over the Greek marked his ninth win against top-ten ranked players in his career.

During the post-match conference, Humbert expressed his joy in defeating a Top 10 player like Tsitsipas and how his last week victory against Andrey Rublev at the China Open gave his confidence a boost.

"I'm so happy. It's a big win against Tsitsipas, a Top 10 player. Last week I beat [Andrey] Rublev so I feel a lot of confidence on court and I'm very proud that I won this match." Humbert said

He also mentioned that he has put in a lot of hard work throughout the year, and his performance has been particularly strong since the Davis Cup in September.

"I'm just enjoying playing tennis. It's a big passion for me. It's all the work during all the year. Since Davis Cup I've played really great tennis and I'm very happy to play like this." He added
