HSIEH Su-wei and Jelena Ostapenko and are set to face the defending champions and top seeds in the Wimbledon ladies’ doubles semi-finals.
Here we get to know tennis ace Su-wei’s off-court partner Frederic Aniere, who’s got some game of his own.
Seeded at No.4, Hsieh Su-wei and Jelena Ostapenko made easy work of their first three matches at Wimbledon 2025, progressing without dropping a set.
Their biggest challenge so far came when they lost the tiebreak after a tight opening set against Sorana Cirstea and Anna Kalinskaya in the quarter-finals.
But the duo powered back to win the next two 6-3, 6-2, setting up a tantalising showdown with defending champions and top seeds Katerina Siniakova and Taylor Townsend on July 11, 2025.
Who is Frederic Aniere?
Frederic Aniere is the longtime boyfriend of Taiwanese tennis star Hsieh Su-wei.
He grew up in Paris and completed his studies in marketing, before entering the property sector and building a career as an estate agent.
The couple met in 2016 when Su-wei was visiting Paris with her coach.
They were introduced by a mutual friend, who suggested Frederic show her around the city.
What began as a friendly outing with her team soon blossomed into a romantic relationship.
The year after they met, Su-wei told AP: “In Taiwan we don’t have a professional tennis court, so I’m always travelling to somewhere to practice with my coach, and then my friend, last year, she introduced me to her friend.
“She said, ‘Oh, I have a friend in Paris — he can take you out for fun,’ and then we just go out to eat, with my team, not just me, and then things worked. And now I am living with him in Paris.”
Frederic’s role in Su-wei’s life extends beyond that of just a boyfriend — after about a year of dating, he left his real estate job to travel full-time with his girlfriend, supporting her on the WTA tour.
He has acted as her travelling coach and practice partner at tournaments and Grand Slams.
In 2019, Frederic told WTAtennis.com: “[Su-wei] knows a lot about tennis.”
“She doesn’t necessarily need someone to tell her what she has to do, because she knows exactly what she has to do herself.
“I’m just here to give her confidence, to have a good time together, and that’s it.

Hsieh Su-wei
“Of course, we talk about tennis, but she knows what she has to do.
“I don’t try to understand her all the time. I just let her be herself, but for sure, she’s interesting, different from other players.
“She has a different way of working. She likes to play with feeling, and she’s like this in life. It’s what goes for her.”
He added: “She does a lot of yoga, a lot of stretching. She doesn’t spend three hours on the court every day.
“If she’s stretching and feeling good in the body, maybe she works more on her fitness. When you get older you have to be even more fit and ready.
“We don’t push her too much but we put out positive energy, which makes it more fun to go out on the court and practice.”
As of July 2025, the couple does not have children.
