Top seed Simona Halep went out of Wimbledon in the third round on Saturday after losing an epic three-set battle against Hsieh Su-wei.
The Taiwanese world number 48's serve was broken seven times and she saved a match point before winning 3-6 6-4 7-5 in two hours and 20 minutes.
It means Czech seventh seed Karolina Pliskova is the only top-10 player remaining in the women's singles draw, reports BBC.
It is the first time Hsieh, 32, has reached the last 16 of the tournament.
She will now play Dominika Cibulkova after the Slovak, who defeated Britain's Johanna Konta in the second round, beat 15th seed Elise Mertens of Belgium 6-2 6-2.
