HAMBURG, March 18, 2025

World No. 1 Jannik Sinner has confirmed his participation in the Hamburg Open scheduled for May 17-24, 2025. The Italian superstar will play at the Rothenbaum Tennis complex for the first time in his career, further elevating an already star-studded ATP 500 tournament lineup.

Before Sinner’s announcement, Stefanos Tsitsipas, Holger Rune, Andrey Rublev, Gael Monfils, and Germany’s Jan-Lennard Struff had already committed to the event. With such an elite field, world-class tennis is guaranteed.

The 23-year-old Sinner recently claimed the Australian Open title in January, marking his third Grand Slam victory. His impressive résumé also includes four ATP Masters 1000 titles and a triumph at the ATP Finals in Turin last November. He will be the first World No. 1 to compete at the Rothenbaum in Hamburg since Roger Federer in 2008.
