Djokovic masters Mensik in Shanghai

Novak Djokovic didn't go anywhere on Friday, but he did secure the essential: a victory and a place in the semi-finals of the Shanghai Masters 1000.

Faced with a surprising Jakub Mensik, who had already beaten Rublev and Dimitrov this week, the Serb needed a little time to find the solution.

After losing the first game in a tie-break (7-6), he dominated the second set before holding off a spirited opponent in the final set to win (6-7, 6-1, 6-4).

More solid in the exchange than Mensik and, above all, far more effective on the important points, Djokovic will now meet Taylor Fritz in the semi-finals.
