Early Life and Tennis Journey
Learner Tien was born on December 2, 2005, in Irvine, California, to Khuong Dan Tien and Huyen Tien, refugees who fled South Vietnam.
His mother, a former math teacher, chose his first name to reflect her belief that life is about constant learning. Tien picked up a racquet as a young child at a facility near his home and won his first tournament at the Racquet Club of Irvine at age five.
He built a strong junior résumé, reaching the boys’ singles final at the 2023 Australian Open juniors and the 2023 US Open juniors, while also winning the Australian Open boys’ doubles title.
He captured back-to-back USTA Boys’ 18s National Championships in Kalamazoo in 2022 and 2023, each earning him a US Open main-draw wildcard. Tien briefly played college tennis at USC before turning professional in late 2023.
Professional Tennis Career
Tien’s breakout arrived at the 2025 Australian Open, where he upset fifth seed Daniil Medvedev in a five-set second-round thriller and reached the fourth round.
He followed that with a win over world No. 2 Alexander Zverev in Acapulco, becoming the youngest American to beat a top-three player since Andy Roddick in 2001.
He won his maiden ATP Tour title at the 2025 Moselle Open in Metz, then capped the season by lifting the 2025 Next Gen ATP Finals trophy.
In 2026, Tien reached his first Grand Slam quarterfinal at the Australian Open after defeating Medvedev again, then won the Geneva Open in May for his second ATP title and first on clay. He entered Wimbledon 2026 seeded 16th, his highest Grand Slam seeding to date.
Coach
Tien has worked with 1989 French Open champion Michael Chang since July 2025, after Chang’s schedule opened up near their homes in Southern California.
Chang joined Tien’s team ahead of the 2025 US Open, where Tien faced Novak Djokovic in the first round.
Traveling coach Erik Kortland, a former USTA Player Development national coach, works alongside Chang on a day-to-day basis. Under this setup, Tien has climbed from outside the top 100 into the top 20.
