There’s a new American tennis prodigy grabbing headlines! 19-year-old Learner Tien is already turning heads at the 2025 Australian Open. On his Grand Slam debut Down Under, Tien cruised into the second round—a milestone achievement for the young talent. But while Tien’s skill and determination are in the spotlight, it’s his supportive family standing firmly in his corner. So, who are the biggest cheerleaders behind this rising star?

Learner Tien was born in Irvine, California, to Vietnamese parents Khuong Dan Tien and Huyen Tien. His parents, both Vietnamese immigrants, didn’t just provide a loving environment for him. Crucially, they also introduced him to tennis. Both Khuong and Huyen played recreationally and passed down their passion for the sport to their son.

Khuong, a real estate lawyer based in Garden Grove, and Huyen, a former math teacher in Anaheim, are dedicated parents who found creative ways to honor their professions. Their children’s names—Learner and Justice—reflect their values. “An attorney seeks justice. A teacher seeks a learner. They were virtuous names,” Khuong explained in an LA Times article.

The young starlet’s tennis journey began almost as soon as he could walk. At just 1.5 years old, he picked up a racket for the first time. By the age of five, he was competing in tournaments, with his debut event held at the Racquet Club of Irvine near their home.

Under his father’s guidance, Tien practiced on community courts in Irvine. Khuong coached him until he was around 10 or 11, nurturing his talent and love for the game. Tien’s first championship came at an event in Upland when he was just shy of six years old. The tournament, held during Halloween, awarded him a trophy adorned with a jack-o’-lantern—a memory his family still cherishes.

Despite his early success, The World No.114 didn’t immediately commit to a professional tennis career. His parents supported his choices, even when he stepped away from the sport. Reflecting on this phase with LA Times, Khuong said, “We never thought much about it other than, ‘Gosh, he was really good. It’s a bit of a shame that he doesn’t enjoy it as much as you would think his talent would cause him to enjoy it.’” But eventually, Tien found his way back to tennis on his own terms. Since then, his achievements have been nothing short of remarkable.

Learner Tien’s journey through the ranks to take on a big name

Learner Tien has already made a name for himself in junior and professional circuits. In 2023, he won the USTA Boys’ 18 national title—twice—and reached two junior Grand Slam finals at the Australian Open and the US Open. He also claimed the 2023 Australian Open junior doubles title.

Currently ranked World No. 114, the 19-year-old American has proven his potential on the ATP Challenger Tour, winning three titles before turning 19. His rapid progress earned him a spot at the 2024 Next Generation ATP Finals.

While Khuong was his son’s first coach, he has since stepped back to let Learner take charge of his career. “This is his profession now,” Khuong said. “From time to time, I send him a text telling him how proud we are of him, that we love him, and to have fun. I leave it at that.” Now, the young qualifier faces an even bigger challenge: a second-round clash with former World No. 1 Daniil Medvedev. The match is set to take place on Thursday evening inside Margaret Court Arena. Will the gritty youngster rise to the occasion and upset one of the game’s mammoths?
