Former grand slam champions Svetlana Kuznetsova and Amelie Mauresmo enter Wimbledon short on match play after Wednesday upsets at the Eastbourne Championships.

Danish teenager Caroline Wozniacki ended the run of top seed Kuznetsova, the 2004 US Open winner, as the Russian turned in a "pretty disgusting" performance to lose 6-2, 6-2 in her opening match.

"I trained so much and then played like this," she said. "It was pretty disgusting. Everything on grass is just the opposite of playing on clay.

"She played very loose and I was so tight. But this match was, I guess, better than none at all."

Mauresmo was felled after 14 minutes by a left thigh injury which has to compromise her chances at Wimbledon, which she won in 2006. Australian Samantha Stosur won the match 1-2 retired.

"I felt something on the last point of my first service game," said the 28-year-old Mauresmo. "In the next game I felt I couldn't move well any more or push off on my left leg.

"I don't feel like taking any more risks before Wimbledon. I'm disappointed but I had to stop here."

Kuznetsova struck a massive eight double-faults in a tricky wind. "I'm very disappointed, but this can happen in tennis."

Wozniacki, the 2006 junior Wimbledon winner, said her victory in just over an hour qualified as the best of her brief career.

"I like the fast, flat game," said the 17-year-old. "Serve and return are so important.

"I’m surprised with how confident I felt. I had never won a set off of of a top player. This is my best win, she's a world number four who has won a Grand Slam.

"I just enjoy playing on grass," said Wozniacki, daughter of a former Poland the Denmark footballing father and volleyball player mother.

Second seed Marion Bartoli, the 2007 Wimbledon finalist, re-discovered the joy of tennis with a 6-3, 6-0 defeat of Sybille Bammer for a last-eight place.

A month after declaring her desire to take a long break from the game, the Frenchwoman is now eager to try and repeat her best career showing at a major.

"Suddenly I feel great, I'm healthy and eager," said the 23-year-old with three career titles. "Losing in the first round at Roland Garros — in your home country at your home grand slam — is tough.

"I was the first French player to lose and it didn't feel good."

Added former Eastbourne semi-finalist Bartoli: "I was frustrated, I've had so many injuries - my wrist, my knee, my leg, my Achilles tendon.

"When you can't train at 100 percent, it's tough. It was heartbreaking to lose so early in Paris. But I feel that the bad things that have happened in the first part of the year will help me out later.

"This is the first week of the year that I've felt this good," said Bartoli, who said she felt no pain from her latest wrist injury.

Ekaterina Makarova added to seeded woes as she put out number three Vera Zvonareva 6-3, 6-3.
