Talent has been a catalyst for the Breakout success of American Teenager Tien student in 2025, but the experience is also a secret weapon. Events event that appears locals in southern California enables him to increase his growing reservoir, and with the new coach Michael Chang on his team, that process is amplified.

Not only is Tien learning as he goes to his first full season as a professional who has seen him collect 23 wins, including five against Top 10, but Southpaw smart also receives the extra benefit of having a former Grand Slam champion of 662 career victories to use as a sound board.
“This is my first year in the tournament, so I think every week I am gaining a lot of experience, playing a lot of new players, playing different environments, just many different matches,” Tien said after falling in Jannik Sinner, 6-2 in the Open Open final on Wednesday. “It’s all great, all these experiences I’m getting.
“I’m just trying to get them all the best.
Tien, who began working with the former world of Chang this summer, says Chang has opened his eyes for a new perspective.
“I’ve never worked with a coach who has played professionally before, not at least at that level,” he told reporters after Beijing’s final. “I think the experience he has played and training brings a lot because I’m a kind of someone starting and I don’t have that much experience. To have a coach that kind has been going through what I’m currently going through, one kind knows that day, what I could think, how I could feel, it’s great.”
Chang does not plan to be a full -time travel coach for Tie, but he made the trip to Beijing.
“I think you don’t have to be a good player to be a good coach. I think only the experience he has from playing and training before has just helped me a lot,” Tien added. “It is a new perspective that is really a kind of step in my eyes. A fresh face, the fresh voice has been great.”
With or without, Tien has proven to be a quick study on the ATP tour. He entered in 2025 with six career wins in his name, as a teenager unproven with a group of seemingly visible weapons. Tien decided Toni early, creating one of Australian Open’s biggest attacks when he overthrew Daniil Medvedev three times in a meeting with five second -round sets.
He may not have the power of garbant, but Tien packs a handful of both sides, and everything he lacks on the power side he does with his trade, cunning and tranquility of the trademark.
It all adds a high career ranking of no.36, and a season that can be a stone in step for bigger things to come.
“You always believe in yourself that you can achieve these things,” Tien said. “You try not to be surprised when it happens. But still when it happens, it feels good. It is very motivating when it strikes these new checkpoints.
“I’ve had some ranking goals and stuff at the beginning of the year I’ve already hit. I’m very happy with the progress I am doing.”
