The talented Czech's second biggest victory: He knocked out Djokovic, and now Siner

Jakub Menšik is a great talent in Czech and world tennis, although he has been in demand for a long time since he sensationally defeated the greatest ever, Novak Djokovic, in the final of the Miami Masters last year.

Today he achieved the second biggest victory of his career - he was better than Janik Siner, the second player on the ATP list.

Menšík, the 16th ranked tennis player in the world, advanced to the semifinals of the tournament in Doha, triumphing over the Italian 7:6 (3), 2:6, 6:3.

In the semifinals, he will meet world number 40 Arthur Fila from France. The other semifinal will feature world number one Carlos Alcaraz from Spain and defending champion in Doha, Russian Andrei Rublev.

Alkaras defeated Russian Karen Khachanov in a upset earlier today.
