First-round matches to watch
Nick Kyrgios (WC) vs. Corentin Moutet [8]
The standout match of the opening round. Two of the most theatrical and unpredictable personalities on the ATP Tour meet in what promises to be unmissable entertainment, even before the first ball has been struck. Kyrgios makes his Stuttgart comeback as a wildcard; Moutet brings his own brand of crafty, combative tennis as the eighth seed.

Daniel Altmaier vs. Frances Tiafoe
A tough draw for the German home hope, who opens against Tiafoe, a former Stuttgart champion (2023). Altmaier will need to be at his best to get through.
Tommy Paul vs Giovanni Mpetschi Perricard
Paul enters as the clear favorite against the hard serving Frenchman. His serve can cause serious damage though on grass.
Tom Gentzsch (WC) vs. Rinky Hijikata
A German wildcard with something to play for: a Gentzsch win could set up an all-German second-round clash with Altmaier, which would be a crowd favourite moment at the Weissenhof.
Diego Dedura (WC) vs. James Duckworth
The young German wildcard gets his first shot at main-draw tennis on home soil.
Jan-Lennard Struff vs. qualifier
The local fan favourite starts against a qualifier and could then face third seed Alexander Bublik in the second round, a real test of where Struff’s game is heading into grass season.
Doubles highlights
The doubles draw has its own headline act: Alexander Bublik and Nick Kyrgios have paired up as a wildcard team – arguably the most entertaining combination imaginable on a grass court. Elsewhere, the all-German wildcard duo of Altmaier and young Justin Engel adds a generational dimension to proceedings.

History & interesting facts
A tournament older than the Open Era
The Stuttgart Open traces its roots back to 1916, making it one of the oldest grass-court tournaments in Europe. For decades it was known as the Mercedes Cup before Hugo BOSS took over title sponsorship in 2022, giving it its current name. The modern grass-court ATP event at the Weissenhof actually only began in 2015 – the tournament had previously been played on clay.
Record holders
- Most titles: Rafael Nadal (3: 2005, 2007, 2015)
- Oldest champion: Roger Federer, aged 36, in 2018
- Youngest champion: Andrei Medvedev, aged just 17, in 1992, also the lowest-ranked champion ever (world no. 100)
- Where legends began: Del Potro, Chardy and Fognini all won their first-ever ATP title in Stuttgart
Defending champion: Taylor Fritz
The American arrives in Stuttgart looking to defend the title he claimed in 2025, defeating Alexander Zverev in the final. Fritz is seeded second this year.
The road to Wimbledon
Stuttgart sits right at the start of the grass-court swing and has long been a crucial warm-up for Wimbledon, which follows just weeks later. The Weissenhof offers players their first real taste of grass-court conditions after the clay season, and several past Stuttgart champions have gone on to deep Wimbledon runs in the same year.
