PARIS - Rafael Nadals back is giving him more trouble than his opponents so far at the French Open. After pushing his winning streak at Roland Garros to 31 matches with a 6-2, 7-5, 6-2 victory over 65th-ranked Leonardo Mayer of Argentina in the third round Saturday, eight-time champion Nadal said his bothersome back is forcing him to cut back on the velocity of his serves. Nadals back also acted up in January during his loss to Stan Wawrinka in the Australian Open final. "During my career, I had (a) few problems. ... Hopefully will not be (the) case" the rest of the way in Paris, the No. 1-ranked Nadal said. "I served more slowly since I started feeling the pain," he said, noting that hes worn tape on his back for extra support. Against Mayer, Nadal averaged only 102 mph (165 kph) on first serves, with a top speed of 114 mph (184 kph). That was down from an average of 111 mph (179 kph) and top of 122 mph (197 kph) in the first round against Robby Ginepri last Monday. Through six sets across his first two matches, Nadal faced only five break points and lost serve only twice. He needed to deal with eight break points against Mayer, losing two. Still, Nadal made only 10 unforced errors all match — two in the first set, three in the second, five in the third — and equaled his longest run at Roland Garros. But the last time Nadal won 31 in a row in Paris, he failed to get No. 32, losing in the fourth round in 2009 to Robin Soderling. That remains the Spaniards only defeat in 63 matches at the tournament. Nadal has dropped 19 games heading into his match against 83rd-ranked Dusan Lajovic of Serbia, who is in the second major of his career and beat Jack Sock of the United States 6-4, 7-5, 6-3. Another American, Donald Young, lost in five sets to Guillermo Garcia-Lopez of Spain, leaving No. 10 John Isner as the last U.S. man in the field. Before this French Open, the 23-year-old Lajovic had a 10-21 career record in tour-level matches, never winning two in a row. "I saw him play a few times on TV. Sure, its great to have new players on tour, young players on the tour that are coming strong. Hopefully not too strong," Nadal said with a smile. "Well see on Monday. I hope to be ready." Asked whether he would seek advice from another Serbian, No. 2 Novak Djokovic, before facing Nadal, Lajovic joked: "Yeah, I will try to ask everybody (for) some tips." That wont help if Nadal produces shots of the sort he did when Mayer served at 5-all in the second set — a stretching, scooping backhand lob to break. As Mayer watched the shot sail overhead, he waved his left hand to signal to the ball to go out, then rolled his eyes when it curled in. At the other end, Nadal pumped his fist, ahead 6-5 and well on his way to reaching the fourth round for the 10th time in 10 trips to Roland Garros. Roger Federer is the only other man to make it to the final 16 in Paris that many years in a row. The man Nadal beat in last years final, No. 5 David Ferrer, defeated No. 32 Andreas Seppi of Italy 6-2, 7-6 (2), 6-3. Ferrer now plays No. 19 Kevin Anderson of South Africa. No. 23 Gael Monfils of France put together a 5-7, 6-2, 6-4, 0-6, 6-2 win over No. 14 Fabio Fognini of Italy in a wild match that included a point penalty for Fognini when he threw his racket and it landed near a ball boy. Monfils and Fognini combined for more than twice as many unforced errors, 137, as winners, 66. Earlier Saturday, No. 15 Sloane Stephens moved into the fourth round for the sixth major in a row. The American now meets No. 4 Simona Halep of Romania. Other fourth-round matchups: 2009 champion Svetlana Kuznetsova against No. 23 Lucie Safavora; 2012 runner-up Sara Errani against No. 6 Jelena Jankovic; No. 28 Andrea Petkovic against 148th-ranked qualifier Kiki Bertens of the Netherlands. As the sun came out and the temperature topped 70 degrees (20 Celsius) after several days of overcast skies and occasional rain, Stephens eliminated No. 22 Ekaterina Makarova of Russia 6-3, 6-4, while Halep beat 55th-ranked Maria-Teresa Torro-Flor of Spain 6-3, 6-0. Halep is the highest seeded woman left, because of losses by No. 1 Serena Williams, No. 2 Li Na and No. 3 Agnieszka Radwanska. Said Halep: "Thats a surprise for everyone."

LONDON -- Arsene Wenger signed a new three-year deal to manage Arsenal until 2017, renewing his commitment to the club on Friday after ending a nine-year trophy drought. The new deal was announced by Arsenal to the London Stock Exchange and will take Wenger into his 21st year at the club, where he has been in charge since 1996. "I want to stay and to continue to develop the team and the club. We are entering a very exciting period," Wenger said on the Arsenal website. "We have a strong squad, financial stability and huge support around the world. We are all determined to bring more success to this club." The 64-year-old Frenchman won three Premier League titles and four FA Cups in the first half of his Arsenal tenure, but failed to capture a trophy since 2005 until winning this seasons FA Cup. Wenger has guided the London side into the Champions League for 17 consecutive seasons and is the longest-serving manager in the Premier League following the retirement of Alex Ferguson at Manchester United last year. "The club has always shown faith in me and Im very grateful for that," Wenger said. "We have gone through fantastic periods and also periods where we have had to stick together. Every time when that togetherness was tested I got the right response. I think I have shown some loyalty as well towards this club and hopefully we can make some more history. I am sure we can." Wenger is Arsenals most successful manager in its history, helping change the face of English football by bringing in new training methods and dietary plans that were regarded as revolutionary in his first years in the country after joining from Japanese club Grampus Eight. Previously, he was at French side Monaco. On the pitch, his Arsenal team broke Uniteds stranglehold oon the Premier League around the turn of the century and then went through a season unbeaten in the 2003-04 campaign, playing an eye-catching brand of football with Thierry Henry, Dennis Bergkamp and Patrick Vieira to the fore to the fore.dddddddddddd Fans patience has been tested in recent years during the trophy drought, however, with dissenters frustrated at Wengers refusal to spend money on big-name players and his unshakeable belief in squad members who didnt appear to be at the required standard. Further criticism was targeted at Wenger for selling star players Cesc Fabregas, Robin van Persie and Samir Nasri to rivals like Barcelona, United and Manchester City. The club-record signing of Germany playmaker Mesut Ozil for 50 million euros ($66 million) last summer suggested a chance in stance in the transfer market from Wenger. "What I can promise is that we work very hard on a market that is very, very congested with many people who have a lot of money," Wenger said. "But we have a big advantage, players want to join us and if we find the right quality Im sure we can strengthen the team." And winning the FA Cup could be the catalyst for a new successful era under the Frenchman, widely regarded as the Premier Leagues only manager who cant be fired. "Sustained excellence is the hardest thing to achieve in sport and the fact Arsenal has competed at the top of the game in England and Europe throughout the time Arsene has been manager, is the ultimate testimony to his consistency of performance, talent and ambition," Arsenals majority owner Stan Kroenke said. "We are delighted with the FA Cup success which has added to his already outstanding record. Under his guidance we look forward to adding more trophies in future seasons." ' ' '
