Rising Stars of American Men’s Tennis: Tien and Michelsen
On a clear morning in December, on a Southern California court, two promising American tennis players, Alex Michelsen and Learner Tien, practiced their game. Nearby, a group played pickleball, unaware of the potential in these young men who are preparing for the upcoming season.
Across the globe, many top players train in exclusive facilities, but Michelsen and Tien chose a local court in Mission Viejo, California, not far from Laguna Beach. Their practice was filled with competitive energy and banter. Michelsen, known for his intense emotions, jokingly criticized his own mistakes.
The duo engaged in a 10-point match tiebreak, practicing with the rules of the Next Gen ATP Finals, which Tien won a week later. Despite playfully discussing mistakes during the match, Michelsen eventually won the tiebreak. Afterward, they discussed relationships and personal growth off the court.
The landscape of American men’s tennis is changing. While the current stars such as Taylor Fritz, Frances Tiafoe, and Tommy Paul face challenges as they age, younger players like Michelsen and Tien are stepping up. Their performances at Grand Slam events are setting the stage for a shift in leadership within American tennis.
Tiafoe’s journey through tennis has been fraught with ambivalence, yet he returned to form at the U.S. Open, showing strong performance. Paul struggled with injuries in 2025 but has been healthier this year, albeit with challenges against strong opponents like Carlos Alcaraz.
Fritz, despite his past achievements, faced a setback against Francisco Cerúndolo at the U.S. Open. Meanwhile, Ben Shelton, 23 years old, leads the new cohort, advancing to the quarterfinals alongside Michelsen. Tien too has a chance to progress further.

Michelsen’s impressive performances showcase his powerful serve and strategic gameplay. He credits his recent success to the conditions favoring his playing style. His growth in accuracy and strategic shot placement is evident.
Tennis often hinges on speed and time management within matches. Michelsen, known for his critical serve, has worked on improving not just its power, but also the precision of his shots.
Both Michelsen and Tien have shifted to more experienced coaches to enhance their game. Tien works with Michael Chang, while Michelsen brought on Kristof Vliegen. These moves aim to refine their skills and strategies further.
While Michelsen and Tien differ in style and approach, with Michelsen’s physical prowess and Tien’s tactical precision, they share a common drive. Their complementary skills and experiences make them a formidable pair, deeply intertwined since their teenage years in Orange County.
Tien’s agile gameplay and Michelsen’s physicality position them well against current and future challenges. Their journey reflects a broader narrative in American men’s tennis: a change is underway, driven by talent, time, and ambition.
