Mirza gets her revenge on Hingis

It was Mirza's first win over Hingis after two previous defeats

Top seed Martina Hingis exited the Korea Open in the second round after going down 4-6 6-0 6-4 to Sania Mirza of India.

Former world number one Hingis had thrashed Mirza 6-1 6-0 on her way to the Kolkata Open title last week.

But Mirza, ranked 59 in the world, was on much better form in the rematch in Seoul and her powerful groundstrokes were too much for the Swiss player.

The 19-year-old now meets Angelique Widjaja in the quarter-finals.

"Every match is a different match and every week is a different week - this proves that," said Mumbai-born Mirza.

"This is the fittest I've been in the last two years and it's the best I've felt this year."

A tired Hingis, who is now ranked eighth in the world, admitted that her opponent deserved to win.

"She was too good today, she played too well," said Hingis. "Some of the angles she was able to play were really amazing.

"She played very well today, much better than last Saturday. I gave her more chances today."

But the 25-year-old added: "I beat her last week so I am not going to beat myself up about this."
