Hsieh Su-wei proudly flew the Taiwanese flag on Friday when she became the first player from her country to reach the last 16 of a grand slam tournament.
The 22-year-old qualifier edged out France's Aravane Rezai 6-2, 6-7, 6-4 and now plays top seed and world number one Justine Henin of Belgium.
World number 158 Hsieh, who plays double-handed on both sides, has now won six matches to get to the fourth round, having come through the qualifying competition.
While Rezai tried to out-power Hsieh, the Taiwanese mixed up the pace, even resorting to moon-ball tactics in an effort both to upset the rhythm of the Frenchwoman and to recover from a series of long rallies.
"She made me run very much and I was tired, so I had to go moon-ball to get more seconds to rest," Hsieh told reporters.
Hsieh began the year by representing Taiwan at the Hopman Cup in Perth, where she claimed a win against world number 38 Gisela Dulko of Argentina.
