Andy Murray returns to Wimbledon on Monday as the reigning champion, the first British man since Fred Perry in 1936 to defend the title.But the pressure to defend the title cant match the pressure Murray felt in the years leading up to last years triumph that ended the nations collective angst at not having had its own countryman raise the championship trophy in 77 years.When Murray defeated Novak Djokovic 6-4, 7-5, 6-4 in front of an adoring Centre Court crowd, Murrays place in British sporting lore was set.Murray, however, didnt do it by himself. Part of the credit has to go to another former champion, Ivan Lendl, who converted Murray over the course of two years from a talented yet tormented player into a focused, determined Grand Slam champion. The pairing resulted in two Grand Slam titles and an Olympic gold medal.Murray and Lendl parted ways this spring in what was described at the time as a mutual decision. It was later revealed in interviews with the British press, however, that the split was not Murrays idea. He admitted to Simon Griggs of The Daily Telegraph to being wounded deeply that the two couldnt come to a workable agreement. Murray took his time finding a new coach, finally turning to another Wimbledon champion French great Amelie Mauresmo, who won Wimbledon in 2006 and coached Marion Bartoli to last years Wimbledon title.Amelie is someone who is able to take all the stress away and make you feel extremely comfortable, Bartoli told the BBC. She prepares you for the worst and gives you some advice in order to deal with that, so when you start to face that situation you are ready. I really felt she was a tremendous help to me ... especially in the final and semifinal.The mens game is also nothing new for Mauresmo, who briefly coached Frenchman Michael Llodra in 2010. The choice of Mauresmo is a good one, according to 18-time Grand Slam champion Chris Evert.Mauresmos very qualified obviously, Evert said. Amelie, shes been a good coach before. I think she and Andy click well together. I like the line he said: My mom, Ive always had sort of the female influence around me concerning my tennis. Women listen more, which is probably true.But the great thing about Andy now is he still has that influence from Lendl. I think there was nobody better for him at that time, a couple years ago, than Lendl.Murrays success with Lendl has prompted other top player to turn to former champions in an effort to find that winning edge.Roger Federer, a 17-time Grand Slam champion, has turned to Stefan Edberg, who has six majors to his credit. Boris Becker, another six-time champion, has joined Novak Djokovics team, which includes longtime coach Marian Vajda.And thats just the tip of the iceberg. Former French Open champion Michael Chang has guided Kei Nishikori of Japan into the top 10, Marin Cilic is working with Goran Ivanisevic, Richard Gasquet has teamed up with Sergi Bruguera, and Ivan Ljubicic has been coaching Milos Raonic.Former Wimbledon runner-up Mark Philippoussis likes the combination of Federer and Edberg, especially at Wimbledon.I believe [Federer] has one more Grand Slam in him, and his best chance is at Wimbledon, Philippoussis told The Irish Times. Working with Stefan Edberg leading up to this, Roger has been more attacking, and if he plays again like [he did] at the Australian Open, then I am calling him to win this one.Dark horses Grigor Dimitrov and Milos Raonic John McEnroe: Two guys that I think have made the biggest advances, who weve been waiting on the longest to potentially do some serious damage at a major event, and theyre starting to show that. That would be Milos Raonic and Grigor Dimitrov. Two guys, if they had a little bit of luck, things fell their way, they could make a real run in this tournament. Dimitrov, a 23-year-old Bulgarian, arrives at Wimbledon ranked No. 13 having won his third tournament of the year last week at the grass-court tuneup at Queens Club. Raonic, a 23-year-old big-serving Canadian, is ranked No. 9 and has the game suited for Wimbledon. Hes consistently been a quarterfinalist all year. Eugenie Bouchard Chris Evert: I think Bouchard has shown a lot of positives in the last six months as far as stepping up, not being afraid to play the top players, not to be afraid to play on a stadium court, dealing with the pressure so well. Especially after the French, she almost beat Maria Sharapova [in the semifinals]. She likes grass. She likes to step in and take the ball early. She has power. I think shes one to watch. The 20-year-old Canadian is ranked No. 13 and has reached the semifinals at both majors this year. She has won 10 of her last 11 matches and is on the verge of breaking into the top 10 for the first time in her career.High and dryWho needs a roof anyway? Weather conditions at Wimbledon are forecasts to be unseasonably warm and dry, at least for the first week of the tournament. Tennis Channel analyst Justin Gimelstob said the warmer weather will result in faster conditions due to lighter air and the ball moving through the air quicker. When the weather is warm, especially for long stretches, the courts get harder and the balls bounce higher, creating a dynamic where the ball picks up speed upon contact with the court surface, Gimelstob said.American hopes WomenTop-ranked Serena Williams hasnt advanced past the fourth round at the years first two majors, but shes a five-time Wimbledon champion and will be the favorite. It wouldnt be a huge leap to see Sloane Stephens make an extended run, as well. But after Saturday, there are two others Americans for fans to keep an eye on No. 47-ranked Madison Keys won her first WTA title at the Aegon International in Eastbourne, England, with a 6-3, 3-6, 7-5 victory over No. 9 Angelique Kerber, and No. 69-ranked Coco Vandeweghe won her first WTA title at the Topshelf Open in the Netherlands with a 6-2, 6-4 grass-court win over Zheng Jie. MenIt will be a long time before top-ranked American John Isners name disappears from the Wimbledon record books after his legendary 11-hour, 5-minute, 183-game marathon against Nicolas Mahut in 2010, but his serve makes him a threat to make a deep run on grass. Seven other Americans are in the top 100, including two-time NCAA champion Steve Johnson, who reached the quarterfinals in grass-court tuneups in Nottingham, England, and Halle, Germany.
