In September 2025, on her WTA 250 debut at the São Paulo Open , Tjen became the first Indonesian woman to reach a WTA quarterfinal since Angelique Widjaja at the 2004 Wismilak International .[ 16] After defeating third-seed Alexandra Eala in the quarterfinals and sixth-seed Francesca Jones in the semifinals,[ 17]
