Adrien Berrut

After an outstanding 2023, marked by significant achievements—including the Swiss U18 Singles Championship title, the European Doubles Championship title, and his first ATP points in both singles and doubles—our athlete has taken another important step forward in 2024.

His first season as a professional has been a transitional year, filled with impressive results:

  • First victory in a professional doubles tournament (M15 in Monastir).
  • Key player for TC Bulle in the NLB (8 wins in 10 matches).
  • Participation in the NLA with CT Neuchâtel.
  • Victory against former Davis Cup player Sandro Ehrat.
  • Named “Most Valuable Player” in a tournament in San Diego in both singles and doubles.
  • Victory in doubles at his first tournament in San Diego.
  • Achieved a new Swiss ranking of N3-35 (+7 places).

In September 2024, he joined the University of San Diego, renowned for its elite tennis program, which has already developed players currently ranked in the Top 160 worldwide. While pursuing his academic and athletic career in the United States, he will remain active in Europe, participating in professional tournaments during the summer and representing Swiss clubs in both the NLA and NLB interclub championships.

We are proud to support this young talent on his journey and look forward to following his progress with great enthusiasm.
