🎙️Mike Gregersen | Interview, January 2026

Hello, introduce yourself please.

My name is Mike Gregersen, I am 16 years old, I was born on June 12, 2009, in Stuttgart, Germany, and I have German nationality. I currently live in Córdoba, Argentina, where my mother was born. I come from a multicultural family since my father is from Denmark.

What languages do you speak?

I speak German, Spanish, and English. My first language was German, and when I moved to Argentina, I enrolled in a German school where I learn German, Spanish, and English.

At what age did you start playing tennis?

I first touched a racket when I was 5 years old, but it wasn’t until I was 13 that I began to focus entirely on the sport and take competitive lessons. From then on, I started competing and playing in tournaments. Because I started “late,” I work three times as hard, prioritizing quality training that will allow me to quickly integrate into the circuit.

Are there other tennis players in your family?

My mom played interclub tournaments in Germany. My dad started playing and loving the sport when he met my mom. Tennis has always been our family sport.

In which tennis club do you train?

I currently train at Club Tenis Río Cosquin.

What is your coaching team?

My coaches are Diego Cortés, Agustín, Valentino, and Santi. My main coach, Diego Cortés, was a very good junior player, ranking in the national top 10. He played in South American and World Junior Championships during the era of Nadal and Del Potro. He then turned professional until he retired due to health problems. He’s a PTR (Professional Tennis Register) coach, which I really value because this methodology is very direct and practical, and it helps me progress quickly.

What is your weekly training routine?

Currently, I’m training tennis in double sessions of two hours each on Mondays, Wednesdays, and Fridays. These are almost individual sessions (with my brother) where I can specifically improve what I need most when competing. I also do some physical conditioning on the court. On Tuesdays and Thursdays, I do one session of physical conditioning at the gym and one tennis session. During school holidays, I have to take advantage of the time to train since my training schedule is limited the rest of the year due to my double school day.

What is your greatest strength as a player, and what do you need to improve?

My greatest strength as a tennis player is perseverance and the drive to be better every day; I never give up. If there’s one thing I’d like to improve, it’s gaining more competitive experience, like some kids who started at age 8. That’s why I push myself even harder and try to participate in as many tournaments as possible to help me grow.

What is your tennis category and national ranking?

In 2026, I’ll play my first year as an under-18. Up until now, I’ve always been within the top 100 of the national ranking, which is a positive achievement considering how competitive Argentina is and having started competing in the under-14 category. That fills me with pride.

What have been your greatest successes so far?

In 2025, I played in the DTB (Deutscher Tennis Bund), the German Tennis Federation, the largest federation in the world. I faced a very demanding league, where I also had to defend every point in another language. I played a full month starting without a ranking and climbed to a very good ranking in just four tournaments, reaching the semifinals and finals in each. That was the turning point of my career so far; setting the bar high and achieving it gave me a lot of confidence.

In which countries have you played tournaments?

I played federated tournaments in Argentina, South American tournaments in Argentina, Paraguay, and Chile, and ITF Junior tournaments in Paraguay and Argentina. In mid-2025, I played federated tournaments in Germany.

Do you have any sponsors?

My only sponsor is Kirschbaum, and naturally I’d like to have a racket sponsor, which is why I’m always trying to improve my ranking. I understand that sponsors focus heavily on results, but I’d like them to also consider the sacrifice involved in combining studying and tennis, and the rapid growth spurt in such a short competitive period.

What is your goal for 2026?

My goal for 2026 is to focus entirely on junior professional tennis and earn my first ITF points, since in 2025 I managed to qualify for several tournaments, reaching the half marathon on multiple occasions.
Another goal is to develop as a tennis player and as a person, and to improve my mindset. For this last goal, I have the support of my emotional coach, and we’re on the right track.

What is your tennis dream?

My dream is to be a tennis player admired in the history of tennis for discipline and perseverance, as someone who showed that with a lot of effort, goals can be achieved.

Who are your favorite tennis players?

My favorite tennis players are Alexander Zverev, Roger Federer, and Brad Gilbert.
Federer because of his elegance, tactical intelligence, and consistency throughout his career.
Zverev because he represents the modern player with power and discipline, who, with his personality and character, was able to return after a major injury.
And Brad Gilbert not so much for his playing style, but for his strategic vision of tennis, his analytical approach, and his impact as a coach and thinker on the sport.

What do you enjoy outside of tennis?

Besides tennis, I like to play my electric guitar, paint, practice some other sports like badminton with my dad, and play strategic board games.

Who would you like to dedicate this interview to?

To my mother, father, and coach, but especially to the first two for all the superhuman effort they’ve been making for several years now. I value both the financial investment and the physical, mental, and health sacrifices they make so that I can improve every day and become a better athlete.

Thank you for the interview, Mike 🙌
Tennis Papers wishes you all the best in your tennis journey 💜🩷
