On song Tsonga topples Djokovic

-Serena Williams, Federer through; Venues ousted

MELBOURNE, (Reuters) – Roger Federer and Serena  Williams needed all their fighting qualities to stay in the  Australian Open on Wednesday after Li Na stunned Venus Williams  to become the second Chinese to reach a grand slam semi-final.

Federer reeled off 13 games in a row to dig himself out of  trouble and beat Russia’s Nikolay Davydenko 2-6 6-3 6-0 7-5 in a  wildly fluctuating match.

Serena was also staring down the barrel in her quarter-final  against Victoria Azarenka of Belarus before she recovered to win  4-6 7-6 6-2.

Her elder sibling might have joined her but threw away a  comfortable lead in her 2-6 7-6 7-5 loss to Li, one of two  Chinese women through to the last four at Melbourne Park.

Federer made it through to his 23rd consecutive grand slam  semi but only after a titanic struggle with Davydenko, who won  the opening set then got an early service break in the second.

“It’s incredible, looking back,” Federer said.

“For some reason I was just a bit worried I wasn’t gonna  make it this time.

“You always believe the streak is gonna be broken but I  stopped thinking about it after the second round and just  started focusing on the tournament.”

The world number one was struggling to stay with Davydenko  as the sun started setting and shadows began creeping on to the  Rod Laver Arena but seized his opportunity when the Russian  suddenly went off the boil.

“I had so many chance to win, many breakpoints,” Davydenko  said.

“I lost the second and third set, and so easy. I cannot  explain what happened.

“You need to be talented. You need to be like Federer.

“You need to be perfect. He’s number one.”

Federer’s next opponent will be Jo-Wilfried Tsonga after the  Frenchman beat Novak Djokovic 7-6 6-7 1-6 6-3 6-1 to avenge his  loss to the Serb in the 2008 Australian final.

Djokovic was heavily criticised after he retired with heat  exhaustion while trying to defend his title last year and the  world number three said he was sick again against Tsonga.

“It was unfortunate that I couldn’t perform on the level  that I wanted to in the fourth and fifth set,” Djokovic said.

“I don’t want to find excuses for my loss but I went to  vomit and I had diarrhoea before the match. Just a terrible  feeling.”

Djokovic dashed from the court as soon as the match was over  as Tsonga leapt into the air and starting blowing kisses to the  centre court crowd.

“I think I was in good shape, maybe better than him,” Tsonga  said.

“I saw he was not very good. But sometimes, you know, he  does that and he wins … I have a lot of sympathy for him.”

SERENA COMEBACK

Serena showed why she remains the toughest woman in the  world to beat, battling back from the brink of defeat to remain  on course to defend the title she won for a fourth time last  year.

The American lost the opening set to Azarenka then went  behind 4-0 in the second as she started to doubt herself before  she rediscovered her self-belief and found a way to win.

“I’m surprised. I didn’t expect to win when I was down in  the second set,” she said.

“I thought if I lost the singles and the doubles, I could  catch a flight on Friday. It’s not what a champion is supposed  to think but I did.”

Venus was two points away from wrapping up a straight-sets  win when she stumbled on her serve and allowed Li back into the  contest. “In tennis you have to close it out. It’s not like there’s a  clock ticking and then suddenly it’s over,” Venus said.

“You just have to close it out. I didn’t do that today.”

The once unimaginable prospect of an all-Chinese final is  suddenly looming as a real possibility after Li followed Zheng  Jie into the semis.

Zheng, the first Chinese to reach a grand slam singles semi  when she made the last four at Wimbledon in 2008, beat Maria  Kirilenko 24 hours earlier and plays Justine Henin in Thursday’s  semis while Li faces the daunting prospect of playing Serena.

Millions of people in China have been following their  matches on television and Li said she was adopting a  philosophical approach to her match against Serena.

“In China we say if you have a tough time and then you  return back, maybe you have good luck for after,” she said. “So  I still believe that.”
