The Serbs qualified for the quarterfinals and left no doubt about their superiority. It continues to solidify its monstrous form, which has so far made it invincible.
The success was 12th for Djokovic against the German veteran, who rarely wins against the big ones. He did it against Novak last year, but this time he had no chance.
In the next round, Djokovic will play with Karen Khachanov, who beat him at the 2018 Masters final in Paris. Last year, however, the Serb triumphed in this clash at the Davis Cup quarterfinals.
To get there, Russian Khachanov defeated Austrian Denis Novak 6: 3, 6: 4.
