Entry List ATP Hamburg Open 2025 featuring Alexander Zverev, Frances Tiafoe and Andrey Rublev after mass withdrawals

The Entry List has been confirmed ahead of the Hamburg Open which is due to take place between 18-24 May, 2025 and is the last tournament before the French Open.

Sinner will only play again in the tournament before at the Italian Open in Rome so he needs that extra match practice before the main Grand Slam return.

Jannik Sinner, Andrey Rublev, Lorenzo Musetti and Stefanos Tsitsipas were all entered but withdrew post Rome. Previously Arthur Fils won the title in 2024 when it was held in the July section. He defeated Alexander Zverev in the final 6-3, 3-6, 7-6.

Zverev will return this year but last minute as he adds some much needed star power to an ailing field. Geneva Open also takes place in the same week and is headlined by Novak Djokovic and Taylor Fritz.

Hamburg sits on the ATP 500 calendar so is much more populated by top stars and with Sinner needing that extra game time this year, it is no shock that he has chosen the event for that purpose. Similar to Novak Djokovic when he needed sudden matches last season and picked Geneva.

Also it shifts back with last year being played in July as a warm-up for the Olympic Games post Wimbledon.
