Andrey Rublev celebrated his 22nd birthday in style, inflicting more Moscow woe on Adrian Mannarino to clinch the Kremlin Cup on home soil.

Home favourite Rublev had failed to win a match at the tournament in six previous visits but was a comprehensive 6-4 6-0 victor over Mannarino, who was beaten by Karen Khachanov in last season's showpiece.

Rublev broke at the first time of asking and that proved enough to clinch an otherwise tight opening set.

But it was one-way traffic in the second with Mannarino – who had not dropped a set in reaching the final – fittingly giving his opponent several gifts to capitulate in a match that lasted a little over an hour.

It marks Rublev's second ATP Tour title and he will break into the world's top 25 for the first time on Monday.
