The Russian wrapped up the win at the Wiener Stadthalle in an hour and 19 minutes on Sunday as he clinched his fifth ATP title of the season.

Unheralded Sonego, ranked at number 42 in the world, had reached the final in the wake of a shock quarter-final win over world number Novak Djokovic but could not repeat the feat against a clinical Rublev.

"This tournament is really special for me because my grandma was also Austrian, so I have Austrian blood," Rublev said during the trophy presentation.

Italian Sonego found no way past Rublev's serve as he failed to inflict a single break.

It ensured Rublev ended the tournament without once surrendering his serve in 38 games – becoming the first player to achieve the feat in an ATP tournament since Alex de Minaur reeled off 42 games at Atlanta in 2019.
