Hsieh Su-Wei is through to the quarterfinals at a major for the first time in her career. The Taiwanese 35-year-old had reached the round of 16 twice, but her longtime coach Paul McNamee always believed that she had the game to push even deeper.
On Sunday, Hsieh knocked out No. 19 seed Marketa Vondrousova in convincing fashion to become the oldest woman to make her Grand Slam singles quarterfinal debut.
"There's only one Su-Wei," McNamee said in press, following her victory.
