The Taiwanese defeated her last opponent in two straight sets. Marketa Vodrousova didn't have a great chance to make a comeback once Su-wei led in the opening set of 5-2. But the Czech was playing with a heavily wrapped thigh and Su-wei took full advantage as she sliced and spinned her shots in that unconventional way to get the win.
Italy's Sara Errani went down to the 71st ranked player's ways and couldn't come back after winning the first set.
Andreescu bowed in straight sets and next on Hsieh's list is Naomi Osaka
"I'm not really looking forward to it.
It's going to be really tough..." Osaka said smilingly after being told who her next opponent would be after defeating Garbine Muguruza in 3 hard fought sets. The Japanese and the Taiwanese have a 4-1 head-to-head yet Osaka isn't taking anything for granted in playing the devious and smart WTA player.
Su-wei doesn't care if she's one of the most difficult to play on the WTA tour, in fact she loves her hold over players. At 35, she is glad to have come this far no matter how long it took her to reach a quarterfinal of a major.
She's looking at each match as an advantage and says that "I have an Australian coach, Australian fitness coach, Australian massage therapist and Australian hitting partner, so it's extra special." Australia is one of Hsieh's favorite places to play and enjoys the atmosphere as she gladly says, "I quite enjoy to practice here...for me I know where to go and eat after the match...to the Thai restaurant I have a very good appetizers and a good drink...I'm not worried about my tennis, if I don't play good, I go enjoy some good food here..."
Speaking about her strategies and tactics she simply says "All I need to do is just ry to play my game." She emphasizes that other players have to be watched because they can "use their game to destroy you."
But WTA players well know the scorn of Hsieh's racket and she has taken down in 5 years the likes of Johanna Konta, Garbine Muguruza, Simona Halep, Angelique Kerber, Karolina Pliskova, Aryna Sabalenka and Bianca Andreescu.
She has also had that win over Naomi Osaka back at the 2019 Miami Open's third round that keeps the Japanese thinking with a 'side eye' It's been two years since they've played but Hsieh is confident that she has the upper hand and if she wins, that's good.
If not, she will enjoy the City of Melbourne that she loves and go on to the next tournament feeling confident that she's did her best.
