Schwärzler, who won his first Challenger title in Skopje in May in his first season on the tour and is currently ranked 348th in the world, also ended his second ATP tournament after the one in Kitzbühel without a win. Zverev, on the other hand, is hunting for his second Vienna title after 2021 this year and will face an American in round two: Alex Michelsen or Marcos Giron. “Vienna is one of my favorite tournaments on the tour – I love the city, love the stadium, love the audience,” Zverev sent a message of love to the Erste Bank Open yesterday.
