What’s the format of the Boss Open 2025?

The BOSS Open 2025 marks the beginning of the grass season on the ATP men’s tour. It’s an ATP 250 tournament that blends tradition and dynamic gameplay — after all, grass completely changes the pace of the game and demands quick adaptation from players.

The format is straightforward: singles and doubles competitions, with a qualifying stage and main draw. The singles champion earns 250 ATP ranking points, with decreasing points distributed throughout the rounds, following standard ATP 250 procedures.

And here’s the best part: being a shorter tournament than the Grand Slams, with fewer rounds, everything moves faster — in every sense!

The surface is one of the tournament’s main characteristics. Grass courts are fast, with low bounce and livelier balls, favoring players with powerful serves, quick movement, and aggressive gameplay.

Slices, volleys, and fast decision-making are essential for anyone aiming to shine in Stuttgart. It’s a tournament that rewards precision and attacking play — which is why it’s often seen as a perfect Wimbledon preview.

What’s the schedule for the Boss Open 2025?

The 2025 ATP Stuttgart tournament kicks off this weekend with singles qualifiers on June 7 and 8. After that, singles and doubles main draw matches begin on Monday (June 9), with daily action leading up to the finals on Sunday (June 14).

Which players are participating in the Boss Open 2025?

In the singles draw, the top home name is Alexander Zverev, currently ranked No. 3 in the world. Italy’s Matteo Berrettini, always dangerous on grass, is back. Taylor Fritz and Tommy Paul are representing the U.S., along with Ben Shelton — one of the hardest servers among the new generation — and Frances Tiafoe.

Nick Kyrgios is also back. Canada will be represented by its powerful duo: Felix Auger-Aliassime and Denis Shapovalov, both looking to find their form again. Among younger players, Alex Michelsen and Brandon Nakashima are also expected to make noise.

Italy is particularly well represented, with Berrettini, Lorenzo Musetti, Matteo Arnaldi, and Lorenzo Sonego. France brings Quentin Halys and Giovanni Mpetshi Perricard, a rising name. Jiri Lehecka of the Czech Republic continues to grow as a threat, while 38-year-old Gael Monfils still delivers a game only he can play. German Jan-Lennard Struff joins as a home-crowd favorite, as does young Brazilian João Fonseca, who’s already proving he can compete with the best.

The doubles draw is also packed with talent. Marcelo Arevalo and Mate Pavic come in as one of the strongest pairings, as do Italians Simone Bolelli and Andrea Vavassori. German duo Kevin Krawietz and Tim Pütz defend their turf, while Marcelo Melo and Rafael Matos represent Brazil.

Other notable pairs include Taylor Fritz and Jiri Lehecka teaming up, Lorenzo Musetti alongside Lorenzo Sonego, and the youth/experience mix of Alex Michelsen with Rajeev Ram. Additional highlights include Sadio Doumbia/Fabien Reboul, Rohan Bopanna/Sander Gille, Francisco Cabral/Lucas Miedler, Alexander Erler/Constantin Frantzen, Christian Harrison/Evan King, and Hendrik Jebens/Albano Olivetti.

Who are the favorites to win the Boss Open 2025?

As Stuttgart’s grass gets perfectly trimmed, all eyes turn to the potential champions — and this year’s competition looks intense!

Let’s start with Alexander Zverev, the home favorite. Playing in Germany, with the crowd behind him and the high-level tennis that’s taken him to the top, Sascha enters as one of the main contenders. If he lands his serve and avoids tense moments, he could go far.

Lorenzo Musetti is another exciting name. Still young, the Italian has proven he can handle pressure. Taylor Fritz brings consistency and power — a lethal combo, especially on grass.

If you’re looking for boldness and youth, Ben Shelton can’t be left out. He’s full of confidence and climbing fast in the rankings. Another American to watch is Frances Tiafoe. With his athleticism and charisma, he’s built for the quicker grass-court points.

Then there’s Nick Kyrgios — always a wildcard. When he’s in top shape, both physically and mentally, he’s a threat to anyone. His powerful serve and unique style make him a natural on grass.

Also in the mix is Felix Auger-Aliassime. He’s had ups and downs, but his talent is unquestionable. And to round out the list, Matteo Berrettini. The Italian knows how to win on grass better than most — he’s already made a Wimbledon final and has the ideal game for this surface: strong serve, sharp forehand, and an on-court presence that demands respect.

With so many top names and rising stars, the BOSS Open 2025 is set to kick off the grass season in style. Whether it’s Zverev’s refined skill, Shelton’s bold plays, or the surprises that only a tournament like this can deliver — one thing is clear: tennis fans are in for a treat!
