The Stuttgart Open, also known as the Boss Open, kicked off the 2025 grass-court season with a bang, drawing tennis fans from around the globe to Germany’s Tennisclub Weissenhof. As of June 14, 2025, this ATP 250 tournament has already delivered thrilling matches, breakout performances, and intense rivalries. Top players like Alexander Zverev and Taylor Fritz have dominated headlines, while young talents like Justin Engel have stolen the spotlight. Whether you’re a die-hard tennis fan or just tuning in, the Stuttgart Open is proving why it’s a must-watch event leading up to Wimbledon.
Zverev Shines at Stuttgart Open
Top seed Alexander Zverev has been a force at the 2025 Stuttgart Open, thrilling home crowds with his powerful game. On June 13, the German star defeated American Brandon Nakashima 7-5, 6-4 to reach the semifinals. Zverev saved both break points he faced, showcasing his resilience on grass. His next challenge is a blockbuster clash against Ben Shelton, who’s fresh off a win over Jiri Lehecka. Zverev’s return to Stuttgart after a five-year absence has fans buzzing, especially after his recent French Open final run. Can he claim his first grass-court title of the year?
The hometown hero’s journey hasn’t been without hurdles. Zverev admitted to making things “complicated” in earlier rounds, but his focus on grass seems sharper than ever. His serve and forehand have been lethal, setting up an exciting semifinal showdown. Fans are eager to see if he can carry this momentum into Wimbledon, which starts June 30.
Fritz and Auger-Aliassime Battle It Out
Another highlight of the Stuttgart Open is the semifinal matchup between Taylor Fritz and Felix Auger-Aliassime. Fritz, the second seed, cruised past Marton Fucsovics 6-3, 6-4 on June 13, without dropping a service game. The American’s grass-court prowess, with a 67.5% career win rate on the surface, makes him a favorite. Meanwhile, Auger-Aliassime stopped 17-year-old German sensation Justin Engel in the quarterfinals with a 7-6(3), 6-3 victory. The Canadian’s 10 aces and 80% first-serve win rate signal he’s hitting peak form.
This clash promises fireworks. Fritz leads their head-to-head, but Auger-Aliassime’s recent resurgence, including titles in Adelaide and Montpellier, adds intrigue. Predictive models give Fritz a slight edge at 56%, but the match could hinge on who handles pressure better. Tennis enthusiasts are glued to this one, as both players eye a deep run to boost their Wimbledon prep.
Teen Star Engel Steals Hearts
The Stuttgart Open also showcased the rise of Justin Engel, a 17-year-old German wildcard who became the youngest grass-court quarterfinalist since Boris Becker in 1985. Engel’s historic run ended against Auger-Aliassime on June 13, but not before he notched his first Top 50 win against Alex Michelsen. At 17 years and eight months, Engel’s poise on grass has drawn comparisons to Rafael Nadal, as he’s the second-youngest player since 1990 to win ATP matches on all three surfaces.
Engel’s fearless play and eloquent confidence have won over fans. His third-set battle against James Duckworth and straight-sets upset over Michelsen showed maturity beyond his years. While his Stuttgart Open journey ended, Engel’s future looks bright, and Germany’s tennis scene has a new star to rally behind.
