2025 ATP Stuttgart Preview

Grass-court tennis returns to Germany as the BOSS Open in Stuttgart sets the tone for the early summer swing. Held at the prestigious TC Weissenhof club, this ATP 250 event blends tradition with a modern flair, offering players their first real test on grass after the long clay season.

With fast conditions, a sleek new stadium look, and a competitive 28-man draw featuring both power servers and crafty all-courters, Stuttgart has become a proving ground for players hoping to make waves before Wimbledon.

Nick Kyrgios, Matteo Berrettini, and Roger Federer have all used Stuttgart as a springboard to deep Wimbledon runs in the past decade.

Player Quotes on the BOSS Open Stuttgart

Stefanos Tsitsipas (2022)

"It's nice to play in a real club, it just feels more personal. I'm not a big fan of locations that are fresh out of the ground and have no tradition."

Michael Berrer (Tournament Ambassador)

"I believe it has developed into one of the most beautiful ATP 250 events on the tour."

Marin Cilic (2021 Champion)

"Experience plays a big part, especially on grass. The conditions can be difficult; the court plays quite quickly."
