Tennis: Russian Nikolay Davydenko wins title in ATP World Tour Finals

Russian defeats del Potro in final: Nikolay Davydenko of Russia won the biggest tournament of his career Sunday, beating U.S. Open champion Juan Martin del Potro of Argentina 6-3, 6-4 to take the title in the season-ending ATP World Tour Finals in London.

Davydenko, who beat top-ranked Roger Federer of Switzerland in the semifinal round, dominated his service games against del Potro, losing five points on serve in the first set and eight in the second.

"Maybe I had good concentration," said Davydenko, who has reached four Grand Slam tournament semifinals but never made a final. "I was surprised."

Del Potro had three chances to break, but Davydenko saved the point in each case.

"He's very fast," del Potro said. "He plays like PlayStation."

Each player was distracted at least once by a crying baby.

"Maybe he's bored watching our match," del Potro said.

In the doubles final, Americans Bob and Mike Bryan defeated Max Mirnyi of Belarus and Andy Ram of Israel 7-6 (7-3), 6-3 to win their third season-ending title and earn the year-end No. 1 world ranking for the fifth time.

Roger Federer pulls out of Japan Open, Shanghai Masters

Roger Federer withdrew from the Japan Open and Shanghai ATP Masters 1000 on Friday, citing the need to rest after a physically challenging year.

The Japan Tennis Association said the top-ranked Federer was withdrawing from the Oct. 5-11 Japan Open, along with the Shanghai tournament the following week.

"After consultation with my team and doctors, I decided to take the difficult decision to withdraw from both tournaments," Federer said in a statement. "This will allow me a chance to give my body a chance to rest, rehabilitate and recover from a physically challenging year."

Federer reached the final of all four Grand Slams this year, winning the French Open for the first time in his career, then breaking Pete Sampras' record with his 15th major title at Wimbledon.

He also earned two points for Switzerland last weekend during a 3-2 victory over Italy in the playoffs to remain in the top-tier World Group of the Davis Cup.

It is the second time Federer has pulled out of the Japan Open just before the start of the tournament. He also cited fatigue as his reason for withdrawing from the 2007 event.

"I'm disappointed that I have to withdraw from Tokyo and Shanghai as they are two of my favorite cities," Federer said. "The fans have been great to me over the years."

U.S. Open champion Juan Martin del Potro and third-ranked Andy Murray are scheduled to take part in the Japan Open.

Spain and Czechs through to final

Spain will host the Czech Republic in the Davis Cup final in December after both countries won their semi-finals.

Tommy Robredo and Feliciano Lopez beat Jonathan Erlich and Andy Ram 7-6 6-7 6-4 6-2 to put Cup holders Spain 3-0 up against Israel in the best-of-five tie.

Radek Stepanek and Tomas Berdych sealed the Czech Republic's win over Croatia with a 6-1 6-3 6-4 victory over Marin Cilic and Lovro Zovko on Saturday.

And Roger Federer helped Switzerland beat Italy in the World Group play-off.

Stepanek and Berdych's triumph came on the back of singles victories for the pair on Friday when the Czech Republic opened up a 2-0 first-day lead in the semi-final, despite Ivo Karlovic firing a record 78 aces.

Karlovic broke his previous ATP record, but still lost in a gruelling five-set match to Stepanek.

In the second singles rubber, Berdych beat Cilic in four sets.

Earlier, champions Spain had secured a 2-0 lead over Israel thanks to convincing singles wins by Juan Carlos Ferrero and David Ferrer.

Ferrero thumped Dudi Sela 6-4 6-2 6-0 after Ferrer thrashed Harel Levy.

Spain went into their semi-final without injured top-10 pair Rafael Nadal and Fernando Verdasco but that mattered little with Ferrer and Ferrero both impressing.

"It certainly wasn't as comfortable a win as it might have looked," said Ferrer, a 6-1 6-4 6-3 winner.

While Spain eased to a 2-0 lead, the Czech Republic only opened up their lead after a marathon day's play.

In total, Stepanek and Karlovic played out 81 games before the first break of serve at 14-14 in the decider.

During that time, Karlovic had sent down 78 aces, 23 more than his previous record in losing in this year's French Open first round to Lleyton Hewitt.

"I did my best, but Stepanek was there all the way," Karlovic said.m "After the loss, the serve record means little."

After sealing the decisive break and serving out for a match that lasted just six minutes shy of six hours, Stepanek said: "Everything is known about Karlovic. He really has a phenomenal serve."

In the second rubber, Cilic - who beat Andy Murray in the US Open - went down 6-3 6-3 3-6 4-6 6-3 to world number 18 Berdych.

Meanwhile, Federer helped Switzerland to a 3-2 win over Italy in Genoa to ensure World Group status for another year.

Federer had only just flown back to Europe following his five-set defeat by Juan Martin Del Potro in Monday's US Open final, but beat Simone Bolelli on Friday and then secured the decisive third point with a 6-3 6-0 6-4 win over Potito Starace on Sunday.

"It was a tough weekend for us and I'm happy I could help Switzerland win," said Federer. "I was able to play very well.

"I have to go on holiday badly. I have a problem with my leg, I have a problem with my arm - everything is hurting."

Other World Group play-off winners were Belgium, Chile, Ecuador, France, India, Serbia and Sweden.

Del Potro's Open win a new chapter for tennis

Twenty-year-old Argentinean Juan Martin del Potro, aka "The Tower of Tandil," won his first major title on Monday at the U.S. Open, where he defeated Roger Federer in five sets. Here are five reasons why his victory changes the tennis landscape more than any win since Rafael Nadal's first French Open title in 2005.

1. He wasn't in awe of Federer. Most of Federer's opponents can't handle the pressure of playing a tennis legend. Pretty much every player on the ATP Tour considers Federer the greatest player of all time, and he's a nice guy, too. Everyone likes him and looks up to him. Not many players, unfortunately, seem to think they are worthy of beating him (Nadal being the exception). Del Potro looked feeble against Federer at the Australian Open earlier this year, when he lost two love sets to him in the quarterfinals, and he started out in similar fashion in the U.S. Open final. By the middle of the match, though, del Potro was playing with confidence and aggressiveness. Few men have been able to do this against Federer, never mind at the U.S. Open, which Federer had won five years in a row.

2. He came from behind. The last man to defeat Federer in a major tournament after trailing two sets to one was Marat Safin in the 2005 Australian Open semifinals. Only two other men have done this against Federer, according to ATPWorldTour.com: Tommy Haas at the 2002 Australian Open and Jiri Novak at Wimbledon in 1999, when the 17-year-old Federer was ranked outside the Top 100. To do it on a stage this large shows how tough del Potro can be.

3. He won without his A-game. The U.S. Open final is the toughest major final in the sport. It's held the day after the semifinals, so the players are a bit more tired than usual. It begins in late-afternoon shadows, and often ends under the lights. This year, the wind was strong. Del Potro hadn't played at night the entire tournament and he plays a riskier game than Federer, which is more dangerous in difficult conditions. He missed far more easy shots in this match than he did against Nadal in the semifinals or, for that matter, in any other round of the tournament. Yet he kept his composure and made adjustments to his tactics when necessary. That's the sign of a champion.

4. He showed off a new weapon. Great players introduce something new to the sport. John McEnroe reinvented touch. Pete Sampras redefined the serve. Ivan Lendl brought fitness to a new level. Federer has super-charged the all-court game of yesteryear; Nadal makes the topspin of the 1980s look like slice. Del Potro's contribution is the hardest forehand in the history of the game (one was clocked at 110 mph). I've never seen a player who could consistently hit winners from four feet behind the baseline and wide of the doubles alley. If del Potro can continue to hit that shot, and even improve it, he'll be a threat to win every tournament he plays.

5. He can get a lot better. Del Potro is 20 years old and hardly in extraordinary condition. He can add muscle to his lanky frame and improve his stamina. He can refine his volley technique and his slice backhand. If he has the desire to do these things, he's going to be a great player for years to come.

Argentina's Juan Martin del Potro dethrones Roger Federer in US

Argentina's Juan Martin del Potro ended Roger Federer's five-year unbeaten reign at the US Open in five dramatic sets to win his first Grand Slam title.

The 20-year-old sixth seed twice fought back from a set down to win 3-6 7-6 (7-5) 4-6 7-6 (7-4) 6-2.

Del Potro is the first man other than Rafael Nadal to beat Federer in the final of a Grand Slam tournament.

Swiss star Federer, 28, had been going for a record-equalling sixth consecutive title at Flushing Meadows.

American Bill Tilden achieved the feat in 1925.

But Federer found Del Potro, in a Grand Slam final for the first time, in determined mood as he became the second Argentine to win the US title after Guillermo Vilas, who was in the Arthur Ashes Stadium to witness his compatriot's victory.

"I had two dreams this week," said Del Potro. "One was to win the US Open and the other one is to be like Roger.

"One is done, but I need to improve a lot to be like you," he said, looking at the five-time champion.

"You fought until the final point. You are a great champion. I'm very happy to be here with this crown, with these people, on this court. This will be in my mind forever."

After a final that lasted four hours and six minutes, Federer said: "I would like to congratulate Juan Martin on an unbelievable tournament. I had a great one but he was the best.

"I would have never believed I could win five in a row here. It has been an amazing run for me."

He added: "I was two points from the match today. That's the way it goes sometimes. But I've had an unbelievable run this year. Being in all major finals and winning two of those.

"Sure, I would have loved to win those two as well. But the year has been amazing already. Got married and had kids, don't know how much more I want."

Federer went into the match on a 40-match unbeaten run in New York, his last defeat coming against another Argentine, David Nalbandian, in the fourth round in 2003.

He also held a 6-0 career record against Del Potro and was playing in his 22nd Grand Slam final, targeting a 16th major win.

However, Del Potro has rocketed up the rankings over the last year and pushed Federer desperately close over five sets in the French Open semi-finals in June.

His 6-2 6-2 6-2 demolition of Nadal in the semi-finals also left no-one in any doubt that he posed a real threat to Federer.

The question was whether he could handle the weight of expectation in a final that Federer has dominated since 2004.

The signs were not good early on as Federer converted his fifth break point of a lengthy second game with a beautiful forehand pass and went on to serve out the set.

Del Potro then double-faulted twice in succession at the start of the second set to hand over another break, and the 23,000 spectators groaned as one as it appeared the younger man was crumbling under the pressure.

It was not until the fourth game of the second set that Del Potro finally made some impression, but Federer saved three break points and looked poised for a two-set lead when serving at 5-4.

The match turned at 30-30 when Del Potro hit a magnificent forehand down the line that was called 'out' but overturned by Hawkeye.

A furious Federer protested to the umpire but there was to be no overruling the computer, and Del Potro then cracked another forehand winner to break back.

From 3-3 in the tie-break, Federer mishit a forehand return before Del Potro came up with two blistering winners and converted his third set point with another.

The sixth seed was now hitting the ball as he had done in his semi-final against Nadal, the power and depth constantly troubling Federer, but after breaking in game seven he allowed his opponent to level at 4-4 by dropping his own serve.

Federer served his way out of trouble in game nine, despite an angry exchange with the umpire over how long Del Potro was taking to challenge with Hawkeye.

Del Potro then appeared to hand the match to Federer in game 10, serving two double-faults in a row to give the world number one a two-sets-to-one lead.

Del Potro's fitness and ability to last five sets at the highest level had remained about the only question mark hanging over his game going into the final, and he was about to dismiss it for good.

Staring down the barrel at 15-40 early in the fourth set, he found two huge forehand winners to save, then broke to love for a 3-2 lead, only to see Federer level at 4-4 with some brave attacking play.

Federer was just two points away from the title in game 10 before Del Potro came storming back to earn break points in game 11.

But a pulsating encounter would require another tie-break.

There was more bad feeling over the use of Hawkeye but it was two missed forehands from Federer that allowed Del Potro to take the match into a fifth set.

It was the first time since Andre Agassi beat Todd Martin 10 years ago that the US Open final had gone to a decider, and the experience and fitness of Federer suggested he would start favourite.

However, the Swiss paid the price for playing to Del Potro's fearsome forehand too often, the Argentine breaking for 2-0 with yet another huge winner.

Federer had one chance in the next game to get back on serve but put a backhand long, and from then on Del Potro played nervelessly.

He reached two championship points on the Federer serve in game eight, converting the second when Federer hit a backhand long.

Andy Murray slips to third in rankings

Britain's Andy Murray has fallen one place in the world rankings to third after being overtaken by Rafael Nadal following the results at the US Open.

Murray was beaten by Marin Cilic in the fourth round at Flushing Meadows, while Nadal reached the semi-finals.

The Spaniard was knocked out by Argentina's Juan Martin del Potro, who went on to win his first Grand Slam.

But Nadal's performance ensured he regained his world number two spot, behind beaten finalist Roger Federer.

Del Potro moved up one place to fifth in the rankings after his victory against Federer.
