LONDON -- Roger Federer had never lost his opening match at the ATP World Tour Finals since the elite tournament moved to London in 2009. Until now, that is. On the back of a chaotic and disappointing season, the former World No. 1 was beaten on Tuesday for the second time in less than a week by defending champion Novak Djokovic 6-4, 6-7 (2), 6-2. The Serb extended his winning streak to 18 matches after capturing his sixth title of the season last week in Paris, where he defeated Federer in the semifinal. Djokovic kept alive his chances of overtaking Rafael Nadal in the race for the year-end No. 1 spot. "It was a big challenge physically," Djokovic said. "Only 48 hours ago I was playing in Paris, so to be able to play this well and beat Roger is incredible. "I have to enjoy the win and then think about the recovery because its a big win. The good thing is, there is a day off. Im going to try and recharge my batteries mentally and physically and get ready for (Juan Martin) Del Potro." Djokovic is attempting to finish No. 1 for the third year in a row but Nadal, who eased past David Ferrer 6-3, 6-2, needs only a win against Stanislas Wawrinka on Wednesday to be guaranteed the top spot. This 31st encounter between Federer and Djokovic -- a remake of last years final -- produced a somewhat disjointed match laced with unforced errors and flashes of brilliant tennis leaving both players looking exhausted toward the end of the match. "Again, I was able to recover from all those matches and actually felt physically somewhat fine," said Federer, who won his last Grand Slam title at Wimbledon in 2012 and has only two victories against top-10 opponents in 2013. "So I regret not having taken my chances better maybe." Federer, the oldest man in the draw at 32, refused to draw early conclusions from a season in which he had back problems and dropped to seventh in the rankings. "The season is not done yet," he said. "Lets talk about this stuff in hopefully four matches." Federer and Djokovic neutralized themselves until the ninth game when the Serb was down 15-30. A double fault gave Federer his first break point, but he sent a forehand wide on the next point. Djokovic then took the next two points to hold his serve. The Serb earned two break points in the next game with a superb backhand return. The cheering from the legion of Swiss supporters packed in the stands didnt help Federer as he fluffed a forehand to lose the set. After rallying from 0-40 to break Djokovic for a 3-2 lead in the second set, Federer dropped his serve in the next game. He double-faulted after Djokovic earned a break point with a backhand that hit the net cord before going over. Serving for the set at 5-4, Federer made another unforced error on his usually reliable forehand to squander a set point. Djokovic seized his chance, sending Federer in the ropes with a stretched crosscourt winner before levelling at 5-5. Federer smashed a ball toward the scoreboard hanging over the court in frustration. Federer kicked back into life in the tiebreak, winning the last five points with a string of beautiful shots that included a backhand volley, a crosscourt winner, and a perfect lob that Djokovic failed to return. Djokovic looked unfazed at the start of the third set to break Federer at love. He then saved a break point to consolidate his lead before taking Federers serve again after a long rally for a 4-1 lead. He sealed the match on his first chance. Despite his easy win, playing indoors will never be ideal for Nadal. The Spaniard has won all four Grand Slam tournaments and the Olympic title in his career but has never triumphed at the season-ending ATP World Tour Finals. "I like the sunshine," Nadal said when asked about the difference between playing indoors and outdoors. "The feeling on the ball, on your racket, is different" when playing indoors, Nadal said. "All of these small things that make you feel a little bit strange." The conditions didnt seem to bother him Tuesday as he beat fellow Spaniard Ferrer 6-3, 6-2 on the indoor court at Londons O2 arena. "Im happy. The court is in perfect condition here," Nadal said. "Its a good start for me, positive one." Nadal came close to winning the event in 2010 when he lost in the final to Federer. He didnt play last year because of a knee injury that kept him away for seven months before his successful comeback in February. The 13-time Grand Slam champion traded early breaks with Ferrer and then began dictating play from the baseline, forcing Ferrer into errors. Nadal converted six of seven break points, and Ferrer had 33 unforced errors. "He arrived a little bit tired after playing the final (in Paris)," Nadal said. "I played with a little more calm than the other day (against him)." Nadal earned his 21st win in 26 matches against Ferrer, but only his first indoors. Nadal and Ferrer play in Group A, along with Stanislas Wawrinka, who beat Tomas Berdych in his opening match on Monday. Djokovic and Federer are in Group B with Juan Martin del Potro and Richard Gasquet. Harry Giles Kings Jersey .

"I dont think my role changes too much," Kane said Monday, as the team prepared to fly to California for games in Anaheim and San Jose. "Obviously you are going to have to earn your ice time and play well and show him what you can do. Other guys have had three games to show what they can do and this will be my first one so Im going to have to be good." The left-winger has been out since Jan. 7 when he suffered a hand injury in a fight during Winnipegs 4-2 home loss to the Tampa Bay Lightning. Although hes missed 12 games due to injury this season, Kane still has 14 goals and 11 assists. The Jets (22-23-5) have won three in a row since Maurice took over but are still a point below .500 as they face two of the toughest teams in the Western Conference. Anaheim (37-9-5) leads the conference and the NHL with 79 points and hasnt lost a game in regulation time at home. San Jose is 16-2-3 in their own building. "We had as much success as we could have had this week, we won three games, so well take whatever thats worth," said Maurice. "Im much more concerned that they have confidence in each other in what were trying to accomplish becoming more clearly defined. I feel in practice that Im seeing the things weve asked them to do come a little bit easier." Maurice said Kane will skate on a line with Mark Scheifele and Blake Wheeler. "I like the possibilities of that line. Id like to think Im going to have some patience with it cause Id like to see it work. At the same time I do have another lineup, Ive got another place as well that I wouldnt mind sseeing him because hes a real strong player and he can be a real benefit to whoever he plays with.dddddddddddd" While on paper the Jets seem no match for either Anaheim or San Jose, "Ive never felt that on a one game," said Maurice. "Over the course of the season yes, in any one game no, the best is not that far from the bottom and thats why its a competition." Kanes father will also be on the road swing, along with other dads as the team hosts a father-son trip. Wheeler says it feels a lot better heading west with three wins behind them instead of three more losses and some confidence that they are playing the way their new coach wants. "It definitely helps to have that confidence, the way were playing and what were doing," he said. He also said theyve been pretty comfortable from the start with what Maurice has been urging them to do. "I think hes trying to utilize the things we do the best to give ourselves a chance to win. Hes trying to use our team speed, use our size, things that we do well to give us an opportunity to play our best every night." Meanwhile, with Dustin Byfugliens move to forward, rookie defenceman Jacob Trouba is seeing a lot of ice time. "Were not running him against the other teams best all night long," said Maurice, but he added that he feels Trouba can hold his own and needs to learn to compete with the best. "Theres going to be some mistakes, we live with those." Trouba had a pair of goals -- including the overtime winner -- Saturday against the Edmonton Oilers. Trouba is now second among all rookie defencemen in goals with seven this season and trails only Bostons Torey Krug who has 10. In points Trouba sits fifth among rookie defencemen with 16. ' ' '
