In the round of the top 16, the second-seeded Hamburger now meets the winner of the game between Alex de Minaur from Australia and the American Tommy Paul. The 25-year-old Zverev had played the final of the Masters in Madrid on Sunday and then a bye in the first round of the clay court event in Rome. He won the title in the Foro Italico in 2017.
Lots of unnecessary mistakes
The German had problems at the beginning of the game and made a lot of unnecessary mistakes. Despite a 6:2 lead, he let himself be caught in the tie-break, but then won the set after 51 minutes.
