“Jannik Sinner informed me in a personal conversation that he will end his 2026 season early. That is, of course, unfortunate, but I fully understand his decision to put his long-term career first and avoid taking any unnecessary risks as he looks to finish the year as World No. 1. He will only return to the ATP Tour once his knee is no longer causing him any problems. I would already like to wish him all the best for his comeback. We will see Jannik in Vienna many more times in the years ahead,” said Tournament Director Herwig Straka.

With five Top 10 stars – Alexander Zverev (GER/2), Daniil Medvedev (5), Flavio Cobolli (ITA/7), Frances Tiafoe (USA/8) and Alex de Minaur (AUS/9) – the Erste Bank Open, offering prize money of €2,797,985, still boasts an outstanding field. In light of the latest developments, Alexander Zverev, who won this season’s Grand Slam tournaments in Paris and New York, could take over the World No. 1 ranking in Vienna.
