An attempt by British-Australian woman Penny Palfrey to swim unassisted from Cuba to Florida ended in failure early Sunday after she had to be pulled out of the water unable to cope with a strong ocean current.

"Penny Palfrey had to be pulled out of the water, after swimming for more than 40 hours," the team said in a tweet.

Australian Honda rider Casey Stoner won Saturday's Dutch Moto GP here after a terrific battle with Spain's Dani Pedrosa, also on a Honda.

Stoner started on pole but soon found himself behind Pedrosa before retaking the lead with nine laps remaining and surging clear to win by a comfortable margin.

Lukas Rosol, the shock Wimbledon conqueror of Rafael Nadal, returned to familiar anonymity on Saturday when Germany's Philipp Kohlschreiber sent him crashing out in the third round.

Czech world 100 Rosol had caused one of the greatest upsets in the history of the sport when he beat world number two Nadal in five sets in the second round under the Centre Court roof on Thursday.

Roger Federer believes the £80 million roof on Wimbledon's famed Centre Court has made a lottery out of the pursuit of the championship title.

The great Swiss, chasing Pete Sampras's record of seven titles, survived an epic battle to defeat France's Julien Benneteau on Friday to reach the last 16.

UEFA president Michel Platini on Saturday suggested that the 2020 edition of the European Championships may be held across Europe, instead of in one or two host countries in what will be its 60th anniversary.

"It's an idea," Platini told a news conference in the Ukrainian capital, Kiev. "There's nothing definitive. In December or January, we will decide whether we will take a bid for one country or two or all of Europe."

Sammy Lee remembers it vividly: food rationing, bombed-out buildings, rubble.

The year was 1948, and London was hosting the Olympics amid severe austerity in the aftermath of World War II. Lee, an American diver, and fellow amateur athletes slept on cots at local air bases and schools, brought their own towels and were ferried to events in old London buses.

Formula One boss Bernie Ecclestone has wanted to stage a grand prix in central London for years and McLaren's British drivers and former world champions Lewis Hamilton and Jenson Button have helped design a track.

But it's nothing more than hypothetical for now.

A Mario Balotelli header and a thumping drive gave Italy a richly deserved 2-1 win over Germany in Thursday's Euro 2012 semi-final in Warsaw.

The 21-year-old struck a first half brace to stun the Germans before a Mesut Ozil penalty reduced the deficit at the death.

Rafael Nadal wrote off his sensational Wimbledon loss to Lukas Rosol as an accident of sport and challenged the Czech, ranked 100 in the world, to make any further headway in the tournament.

World number two Nadal, the 2008 and 2010 champion, and 11-time Grand Slam title winner, suffered one of the greatest shocks in tennis history against a man whose only five other Wimbledon visits had ended in first round defeats in qualifying.

Maria Sharapova's latest win at Wimbledon took two days and considerable resilience.

The top-ranked Sharapova was on the verge of victory Thursday when her old serving problems briefly resurfaced. The lapse cost her the second set, but she recovered to beat dangerous Tsvetana Pironkova, 7-6 (3), 6-7 (3), 6-0.
