South Korea have seven points from four games in Pool A, two behind leaders Spain and narrowly ahead of New Zealand and Germany, all of whom play their fourth matches later today.

Greece's defending Olympic women's 400 meters hurdles champion Fani Halkia failed a drugs test and faces an immediate disciplinary investigation by the International Olympic Committee.

"Halkia tested positive for drugs," one official told Reuters on Sunday.

The official said the athlete had been tested a day before boarding the plane to Japan and that test was negative so any banned substance was introduced in her body in Japan.

"We can confirm her test was under the IOC auspices as it took place within the Olympic period," IOC spokeswoman Emmanuelle Moreau said.

"As normal we will activate our normal procedure, namely a disciplinary commission, in the coming days," she said.

Halkia's A sample tested positive for methyltrienolone, better known as M3, a banned steroid, and her B sample would be tested later in the day, the Greek Olympic Committee (HOC) told Reuters.

The IOC had earlier said it did not have to wait for the results of the B sample to investigate whether there was a violation of an anti-doping rule.

The Greek hurdler confirmed her test was positive and said she was shocked by the news, denying any wrongdoing.

Britta Steffen of Germany won a freestyle sprint double on Sunday as she took gold in the women's 50m Freestyle in an Olympic record of 24.06 seconds at the National Aquatics Center on Sunday, adding to the 100m Freestyle gold she won on Friday.

Steffen, who qualified third fastest for the final in 24.43, was not the quickest off the blocks but recovered to overpower the field and touch the wall first in a wall of whitewater.

Dara Torres of the United States, the 41-year-old mother of one, was out to show her competitors that her age is no barrier in the splash and dash. She clocked the fastest time into the final and recorded the second fastest reaction time but could only manage the silver medal behind Steffen. Torres also set an Americas record of 24.07.

Blake, who ended Swiss world number one Roger Federer's run in the singles on Thursday, made a scrap of it in the second set and Djokovic became rattled, smashing his racket at 4-4.

However, the Australian Open champion went 6-4 ahead in the tiebreaker and fell to his knees in joy when Blake put a backhand into the tramlines.

But he left the medal at the centre of the competition mat before stalking off the stage with a raised clenched right fist.

Abrahamian thought he had beaten Andrea Minguzzi, the eventual gold medallist, in the semi-finals, but the match was awarded to the Italian.

Serbia lodged a protest over the result of the men's 100 metres butterfly final on Saturday after Milorad Cavic was beaten by 0.01 seconds by American Michael Phelps.

Phelps clocked 50.58 seconds to beat Cavic on the final stroke and claim his seventh gold medal of the Beijing Games, equalling Mark Spitz's 1972 record of golds at a single Olympics.

"We have made an official protest. It's first place, it is very important," Serbia's deputy chef de mission Branislav Jevtic said.

Jevtic did not provide specific details about the protest but the complaint was believed to be over whether the timing system worked properly and whether the Serbian touched the wall first.

FINA, the sport's world governing body, would not immediately comment but scheduled a press conference for later on Saturday.

Cavic said he would prefer the protest was dropped.

"If it was up to me I would drop the protest, I didn't want to fight it," he said.

"As we all know, technology is imperfect, it's possible (it malfunctioned)."

Valeriy Borchin clocked the fastest time to win gold in the men's 20km Walk at the Beijing 2008 Olympic Games on Saturday.

His time of 1 hour 19:01 minutes put him ahead of Jefferson Perez of Ecuador by 0.14 seconds.

The bronze medal went to Jared Tallent of Australia, who finished in 1 hour 19:42 minutes.

Britain's Rebecca Adlington broke the oldest world record in swimming to win the women's 800 metres freestyle gold medal at the Beijing Olympics on Saturday.

Adlington, 19, cruised to the gold medal in eight minutes 14.10 seconds to slash 2.12 seconds off the old mark of 8:16.22 set by American Janet Evans in Tokyo in 1989.

Italian Alessia Filippi finished a distant second in 8:20.23 to collect the silver while Denmark's Lotte Friis was third in 8:23.03 to get the bronze.

Adlington, 19, also won the 400 freestyle final earlier in the week to end Britain's 20-year drought for an Olympic swimming champion. It was also the first win by a British female swimmer since 1960.

Michael Phelps matched fellow-American swimmer Mark Spitz's 1972 record of seven golds in one Games on Saturday with yet another victory in the pool.

Guaranteeing his status as the face of the Beijing 2008 Olympics, the 23-year-old Phelps powered to victory in the 100 metres butterfly in front of an ecstatic crowd in the Water Cube with just one hundredth of a second to spare.

The 23-year-old phenomenon now has 13 career golds, four more than anyone else. As well as Olympic glory, Saturday's win brings him a $1 million bonus from sponsors.

James Blake blew his gold medal chance in the men's singles on Friday, then accused Chile's Fernando Gonzalez of trampling over the Olympic ideals.

Gonzalez set up a men's singles final against Spain's Rafael Nadal, saving three match points on his way to a 4-6, 7-5, 11-9 victory, but promptly came under fire from the angry American.

There was no bad blood to spice second seed Nadal's late night blockbuster with Serbia's Novak Djokovic. The two warriors produced a semi-final of rare quality which Nadal took 6-4, 1-6, 6-4 when his weary opponent blazed an easy smash out.

The 28-year-old's grievance stemmed from an incident when he led 9-8 in the decider. He hit a forehand just over the baseline but was convinced the ball had shaved Gonzalez's racket frame as the Chilean took evasive action.

Television replays seemed to suggest he was correct.

"Playing in the Olympics, in what's supposed to be considered a gentleman's sport, that's a time to call it on yourself," Blake told reporters.

"Fernando looked me square in the eye and didn't call it. Maybe I shouldn't expect people to hold themselves to high standards of sportsmanship. But yes, I did expect it a little more so in the Olympics."

Roger Federer bounced back from his dismal singles defeat to sweep into the finals of the Olympic doubles on Friday with a stunning victory over the top-seeded Bryan brothers from the United States.

Federer, serving superbly and constantly attacking at the net, combined with fellow Swiss Stanislaw Wawrinka for a 7-6, 6-4 victory that could give him the gold that has eluded him in a glittering career.

Playing on a sun-kissed court after their match had to be postponed on Thursday due to torrential rain, Federer and Wawrinka first scored an impressive 6-2, 6-4 win over India's Mahesh Bhupathi and Leander Paes.

Zimbabwe's Kirsty Coventry won the women's 200 meters backstroke on Saturday with a new world record time of 2:05.24s to defend her Olympic title.

Coventry, who had won three silvers already in Beijing, led throughout and was nearly a full second ahead of Margaret Hoelzer of the United States who took silver.

Japan's Reiko Nakamura took the bronze medal.

Coventry's time was 0.85 faster than the previous world record time set by Hoelzer at the U.S trials in Omaha in July.

Brazilian Cesar Filho Cielo claimed gold in the men's 50m Freestyle with a time of 21.30 seconds on Saturday.

France's Amaury Leveaux (21.45) and Alain Bernard (21.49) touched in second and third.

World record holder Eamon Sullivan of Australia finished sixth in 21.65s.
