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.

When Kurt Busch slammed into the wall, spewing debris on the track, Loganos 2.2-second lead over teammate Brad Keselowski was gone and he didnt get to take the white flag that would have guaranteed no extra laps. On the ensuing pit stop, Gordon took only two tires and exited first. Both Team Penske drivers took four tires, and Logano got a splash of fuel. But Keselowski missed a chance to become this seasons first two-time winner when he was penalized for speeding on pit road and finished 15th. "I was just trying to get a little too much on pit road," Keselowski said. "Were in it for wins. Were not in it for second. Second or 15th is the same for us." The 23-year-old Logano got his fourth career victory, and Jeff Gordon took over the series point lead from Dale Earnhardt Jr., who had an early crash. "He crossed over and got into the back of me pretty good," Gordon said of the last lap with Logano. "At that point, I was just thinking, I just want to finish. Looked out my mirror, those guys were racing hard behind me. A great, great second-place finish for me." Here are five other things that happened in the rain-delayed race at Texas: 7 WINNERS FOR 7 RACES: Logano became the seventh different winner in as many Sprint Cup races this season, when new rules for the championship Chase put an increased emphasis on winning. Team Penske joined Stewart-Haas Racing as the only teams with multiple winners this season. JUNIORS MISTAKE: Earnhardt finished last for the first time in seven seasons with an early mistake that also made aa long day for Hendrick teammate Jimmie Johnson.dddddddddddd Only 13 laps into the race, Earnhardt drove his No. 88 Chevrolet halfway into the rain-saturated infield grass before it shot across the track and slammed into the wall in a fiery crash. Debris and mud from that damaged Johnsons windshield and front left side. "It was kind of surreal what happened," said Johnson, who later had a right rear tire issue and finished 25th. Earnhardt tweeted: "That wasnt fun. Sorry 2 the fans of the 88 team. Feel bad for my guys and the 48 team also. Made a mistake there that was costly for every1." The last time Earnhardt finished 43rd was the 2007 fall race at Phoenix -- a span of 222 races. HARVICKS BLOWN ENGINE: Kevin Harvick has finished 36th or worse in four of the five races since winning at Phoenix the second week of the season. He started third at Texas, but completed only 28 laps because of a blown engine right after a restart and wound up 42nd. "Its frustrating. I dont know what else I can say," Harvick said. "I didnt get any indication that anything was going wrong." FLAPPIN IN THE WIND: The race started with 10 caution laps to make sure the 1 1/2-mile high-banked track was ready for racing after being postponed Sunday by rain. There were jet dryers on the track during those laps, and the high-pressure air from those affected the hood and roof flaps on several cars. Keselowski made four trips down pit road after his hood popped up and his crew made repairs. "It was one of those freak deals," Keselowski said. Gordon said one of the jet dryers "about blew all of us over." NASCAR put all the cars in their original starting spots. "Im not sure whats more odd, if that happened or NASCAR allowed those guys to repair that thing," Gordon said. "Had a piece of concrete fly through my car once at Martinsville. I dont ever remember them letting me repair the car." STEWART LEADING: Tony Stewart was the polesitter and led laps for the first time season, and not only the first 10 laps during that competition caution to start the race. He 74 of the first 76 laps, and went on to a 10th-place finish. Those also made him the career leader for laps led at Texas Motor Speedway with 801. ' ' '
