Superstar vs. super talent, defending champion vs. debutant: no matter who Austria's great tennis hope Joel Schwärzler serves against at Red Bull BassLine - it will be a great experience for him to compete against the best tennis players in the world on the center court of the Wiener Stadthalle. The challenges could hardly be greater. With Alexander Zverev, the Red Bull BassLine defending champion is back at the start - and with US star Taylor Fritz, a player in top form is sure to serve with great ambitions. After all, it's no coincidence that the 26-year-old reached the US Open final just a few weeks ago. What makes Taylor Fritz particularly “dangerous” is that he already knows the Red Bull BassLine setting from his appearance in 2022 - you can definitely expect top-class tennis!
