Sharapova and Roddick slump out, Nadal grinds down Gulbis

Third seed Maria Sharapova was floored at Wimbledon yesterday by the daughter of a Greco-Roman wrestler.

Ranked 154th in the world, Alla Kudryavtseva had barely registered on the tennis radar but that did not stop her humiliating 2004 champion Sharapova 6-2 6-4.

After a driving forehand sealed the biggest win of her career, Kudryavtseva leapt into the air and shrieked in delight.

"I did expect to win, so yes I believe it!" said Kudryavtseva, who had come within two points of knocking out Venus Williams in the first round 12 months ago.

A day after third seed Novak Djokovic was ejected from the tournament, Janko Tipsarevic kept alive Serbian interest in the men's draw by squeezing past twice former runner-up and sixth seed Andy Roddick 6-7 7-5 6-4 7-6.

Champion Venus Williams and Rafael Nadal also suffered a few anxious moments but lived to fight another day.

Williams, seeking a fifth singles title at the All England Club, had to draw on all her big-match experience to repel world number 92 Anne Keothavong 7-5 6-2. Nadal also endured first-set jitters before he toppled rising Latvian Ernests Gulbis 5-7 6-2 7-6 6-3.

Sharapova certainly looked very fragile yesterday and, for the second grand slam running, she had no one but herself to blame for her listless performance. The Russian hit 43 double faults during her four-match stay at Roland Garros and yesterday produced another eight.

Tipsarevic went for his shots, withstanding a barrage of aces to subdue Roddick.

The American had been hoping to challenge Nadal and five-times champion Roger Federer for the title this year but instead suffered his earliest defeat in eight visits to the All England Club. His exit left the men's draw without three of the top six seeds since Nikolay Davydenko flopped in the first round.

Spanish second seed Nadal had been hoping for a brisk workout against the 48th ranked Gulbis but instead dropped a set at a grand slam for the first time since the Australian Open in January.

Nadal slipped and slid at the baseline but regained his composure to wear down Gulbis.

Attempting to become the first man since Bjorn Borg in 1980 to win Roland Garros and Wimbledon in the same season, Nadal will next be up against Germany's Nicolas Kiefer.

Andy Murray, the 12th seed, avoided any drama and kept the British faithful happy with a ruthless 6-4 6-2 6-2 win over former semi-finalist Xavier Malisse.

Jelena Jankovic romped into the third round with a 6-1 6-3 win over Spain's Carla Suarez Navarro.

French Open finalist Dinara Safina found her comfort zone on grass to coast past Taiwan's Hsieh Su-wei 6-3 6-2.
