Novak Djokovic has again been denied his first title this year.
The world No 1 was beaten 2-6 7-6 (7-4) 0-6 by Andrey Rublev in the final of his home ATP tournament in Belgrade on Sunday.
Serbian Djokovic has played relatively little this season.
This is due to his refusal to be vaccinated against the Coronavirus, preventing his participation in various competitions.
However, his run to a first final of the season would have boosted his hopes of a strong French Open in four weeks.
But he was eventually well beaten by Russia’s Rublev over two hours 26 minutes.
