Jannik Sinner said he was "very proud" of the level he played at as he stormed to a straight-sets victory against Diego Schwartzman in the final of the ATP European Open on Sunday.

The number one seed continued his impressive form in the tournament by sweeping aside his opponent 6-2 6-2 in just 76 minutes.

Sinner was too powerful for his Argentine opponent and showed just why he is considered to be one of the rising stars of tennis with some breathtaking winners from all over the court in Antwerp, Belgium.

"I felt great on court. I moved well. I also served better, I think," the 20-year old said. "I felt great, but in tennis every day is different. You have to be careful. I think I played well the whole tournament, to be honest, from the first point to the last point.

"I like to play indoors. I tried to push the ball [through the court], which for me was important against Diego because he is moving very well. He's not missing so many shots. For me it was important trying to adapt the game somehow against him.

"I think I can be very proud about the level I played."

Sinner is the youngest player to claim five ATP Tour-level titles since Novak Djokovic did the same in Estoril in 2007 at the age of 19.

The Italian is also the fifth player to win at least four Tour-level titles this year, along with Casper Ruud (5), Daniil Medvedev (4), Alexander Zverev (4) and Djokovic (4).

Sinner did not drop a set all week on his way to the trophy, and he now climbs to 10th in the FedEx ATP Race to Turin as he aims to qualify for a spot at the ATP Finals. 

With Rafael Nadal out for the season due to a foot injury, Sinner is now just one place and 110 points behind Hubert Hurkacz in ninth as the race for the final qualifying spot heats up.
