Shaban emerged victorious

Medina, who was kicked out of the event for using a non-approved bat to beat Shaban in their first match, lost 4-3 to the Jordanian second time around.

Officials had given Medina another opportunity after it emerged that her bat had been cleared before the match.

"I've played with this racket for 10 years and then yesterday they say the pimples are wrong," she said.

Meanwhile, 42-year-old Chinese-born Kiwi Li Chunli, competing for New Zealand, booked a meeting with former compatriot and world number one Zhang Yining.

Honduran wins reprieve

Zhang, and countrywomen Wang Nan and Niu Jianfeng, are the top three seeds in the singles at Athens, while compatriots Wang Liqin and Ma Lin are the top two in the men's draw.

After winning all singles and doubles events at the past two Olympics, the Chinese team are the hot favourites in all four events but Li said she had a chance to beat Zhang.

"They [Chinese players] always win so it's very hard and they win because they have very good technique," Li said after beating American Tawny Banh 4-1 in the second round.

"But this time I'm looking to win and I have been training very hard. They are also human. They are not Gods. If they do not play well, they can also get nervous."

In other second-round action, Thailand's Nanthana Komwong's pulled off a shock 4-1 win over Germany's Nicole Struse.

"This is the best win of my career," said Komwong, ranked 54 places below Struse at 84.
