Eighth-seeded Justine Henin-Hardenne upset number one Lindsay Davenport 2-6, 6-2, 6-3 on Tuesday to advance to the Australian Open semifinals.
The loss may cost Davenport, who lost the final here last year to Serena Williams, the top ranking that she has held since October 24.
Kim Clijsters or Amelie Mauresmo, who face quarterfinal matches Wednesday, both have a shot at becoming the new number one.
Henin-Hardenne next faces fourth-seeded Maria Sharapova, who overcame troubles with the gusty winds in the Rod Laver Arena and saved two set points in an error-filled tiebreaker before ousting sixth-seeded Nadia Petrova 7-6 (6), 6-4.
”It was definitely not easy,” said Sharapova, the 2004 Wimbledon champion. ”It was a miracle when someone held serve.”
The wind also played havoc with the serves of Davenport and Henin-Hardenne, who combined for 13 service breaks and 18 double faults.
With Oscar-winning actress Charlize Theron watching, Henin-Hardenne had her serve broken all four times in dropping the first set. After her fourth double fault on break point gave Davenport a 5-2 lead, Henin-Hardenne angrily whacked the ball into the net.
Davenport returned the favour, double faulting on set point to level the match at 1-1.
Henin-Hardenne, the reigning French Open champion and the 2004 winner here, finally got the break that really mattered, converting on her fourth opportunity with Davenport serving at 2-3 in the third set.
She withstood three double faults in her last two service games, finishing off the match when Davenport sent a backhand service return long.
”I think I played pretty solid in the second and the third sets,” said Henin-Hardenne. ”She put me under a lot of pressure in the first but I kept fighting.
”It’s been pretty emotional at the end of the match … it is when you qualify for the semifinals of a Grand Slam.”
Henin-Hardenne, who spent the end of last season sidelined with a right hamstring injury, was anticipating a tough semifinal against Sharapova, who is coming back from a shoulder problem.
”It’s going to be a tough semifinal,” the 23-year-old Belgian said. ”She has confidence and wants to be in the final, so it’s going to be a great match.”
Demonstrating her refuse-to-lose mentality, Sharapova survived two set points in an error-filled tiebreaker after Petrova twice served for the first set.
Petrova struggled with her serve and finished with 12 double-faults, including one serving for the first set at 6-5, another facing set point in the tiebreaker and one to surrender another break at 1-3 in the second.
It was a testy match for both players. Petrova has clashed in the past with Sharapova’s father Yuri, who loudly encourages his daughter.
Sharapova looked in his direction frequently, for what she called ”inspiration” and ”motivation”.
”I just tried to ignore him completely,” Petrova said. ”I didn’t look at his side once.”
In tears at times and spiking her racket into the court at the baseline and from a court-side chair during a changeover, a frustrated Petrova finished with 16 winners and 49 unforced errors.
”I just feel like I simply gave it away,” said Petrova, who said she needs to work on her toughness. ”It couldn’t be a better present.”
Sharapova was frustrated, too. The 18-year-old Russian had 15 winners and 36 unforced errors but still made it 3-0 against Petrova in three straight Grand Slam quarterfinals.
”I get unhappy when I make six double-faults in four service games,” she said. ”I just tried to hang in there.”
On the men’s side, Masters Cup champion David Nalbandian reached the semifinals — completing a full set at the majors — when he overwhelmed veteran Frenchman Fabrice Santoro 7-5, 6-0, 6-0.
The fourth-seeded Nalbandian was down a break in the first set, but took the last 14 consecutive games.
Santoro (33) and playing in the quarterfinals for the first time in 54 majors, never had a game point after holding at 5-5 in the first.
”After that first set, he just gave me a lesson,” Santoro said.
”I try many things, but he has the answer all the time. He just played great tennis, wonderful.”
Santoro had Nalbandian sprinting from side to side, net to baseline, chasing drop shots, volleys and lobs until the 24-year-old Argentine got his ground strokes working and started passing him on both sides.
”In the beginning it was very tough, windy,” said Nalbandian. ”I was a bit nervous. When I got a bit of confidence, I started hitting harder and better, with angles near to the line,” Nalbandian said.
Nalbandian clinched it with his 47th winner.
He will play the winner of the later quarterfinal between number seven Ivan Ljubicic and unseeded Marcos Baghdatis, who upset second-seeded Andy Roddick in the fourth round.
Nalbandian, who lost in the quarterfinals in the previous three Australian Opens, said his upset win over top-ranked Roger Federer in the season-ending Masters Cup at Shanghai in November had increased his confidence. – Sapa-AP
