On June 10, 2025, in Stuttgart, Germany, the ATP Stuttgart Open will witness a compelling first-round match between rising American star Alex Michelsen and seasoned French veteran Gaël Monfils. Taking place at Tennis Club Weissenhof on grass courts, this ATP 250 event sets the stage for a captivating contest that highlights youth against experience.
This encounter will be broadcast live on Tennis TV, drawing attention from fans eager to see how the powerful 20-year-old Michelsen fares against the tactically adept, 38-year-old Monfils.
Analyzing Alex Michelsen’s Journey and Grass-Court Strengths
Alex Michelsen, seeded seventh in Stuttgart and ranked No. 35 worldwide, has emerged as a notable contender on grass surfaces. The young American has steadily built his credentials with strong performances, including a final appearance at Newport and quarterfinal runs in Mallorca in consecutive years, 2023 and 2024. His current season shows persistence with around a 60% win rate on grass courts during the 2025 grass swing.
Despite these strengths, Michelsen faced early challenges this year on clay, bowing out in the first round at the French Open after a loss to Juan Manuel Cerundolo and a defeat to Nuno Borges in Geneva. However, he rebounded by capturing the Challenger 175 title in Estoril in May, proving his ability to adapt and compete effectively on slower surfaces as well. Heading into Stuttgart, he aims to leverage his powerful serve and aggressive forecourt play to build momentum ahead of Wimbledon.

Gaël Monfils: Veteran Skills and Proven Success on Grass
Gaël Monfils arrives at Stuttgart ranked No. 42, continuing his long-standing presence on the ATP Tour since 2004. He reached a career-high ranking of No. 6 in 2016, has advanced to Grand Slam semifinals, and holds 13 ATP titles. Earlier this year, he made history by winning in Auckland as the oldest tour-level champion since 1977, underscoring his enduring competitiveness.
Monfils’ 2025 clay season was mixed, compiling a 3–3 record and falling in the second round of Roland Garros to Jack Draper. However, his proficiency on grass remains formidable, possessing a 58% career win rate on the surface. Known for dynamic movement, rapid forehands, and sharp net approaches, Monfils continues to be a threat as the grass-court season progresses.
Head-to-Head Context: First Encounter Between Michelsen and Monfils
This matchup marks the first time these two players will meet on the ATP Tour. While Monfils brings nearly two decades of competitive experience and tactical savvy, Michelsen arrives as the youthful contender eager to prove himself on this significant stage. This fresh rivalry promises an intriguing contrast in styles and career phases.
Match Prediction and Tactical Breakdown
Though analysts give Monfils a slight edge with a 56% win probability, this contest could swing either way. Michelsen’s 2025 season statistics highlight an aggressive serve, averaging 4.56 aces per match with a first-serve accuracy of 66.8%, though he also registers 2.6 double faults on average. His performance in tiebreak situations has been solid, converting nearly half of those critical points.
Meanwhile, Monfils continues to be a grass-court threat, leveraging his vast experience and a well-rounded skill set. His career record of 582 wins against 343 losses reflects consistency, and his recent form includes a tournament victory in Auckland and a competitive showing at the French Open.
On grass, Michelsen’s matches this year have largely ended in straight sets thanks to his attacking style, while Monfils is known for prolonging rallies and forcing difficult, decisive sets. The clash of Michelsen’s raw power and Monfils’ strategic finesse sets up what could become an intense three-set battle.
Overall, Monfils is favored for his experience and steady recent form, but Michelsen’s aggressive game and youthful energy suggest this match could extend to a thrilling conclusion that tests both players’ resilience.
