A fans’ favourite in Paris, he has dramatically improved his level of French in recent years.”These two weeks might be the most important in the whole season (for me),” Djokovic said after defeating 95th-ranked Yen-hsun Lu of Taiwan 6-4, 6-1, 6-1.Djokovic was in complete control, broke his opponent seven times, and closed the match with a drop shot. He joined his main rivals Rafael Nadal and Andy Murray in the second round.MURRAY CLAWS BACKSeeded No. 2 in Paris for the first time, Murray rallied to win from two sets down for the ninth time, and beat Czech qualifier Radek Stepanek 3-6, 3-6, 6-0, 6-3, 7-5.While Murray needed two days to progress, nine-time champion Nadal had a much easier time, easing past Sam Groth 6-1, 6-1, 6-1.KERBER BOWS OUTIn the women’s draw, Australian Open champion Angelique Kerber lost in the first round. Hampered by a left shoulder injury, the third-seeded Kerber was upset by 58th-ranked Kiki Bertens of the Netherlands 6-2, 3-6, 6-3.Francesca Schiavone, the 2010 French Open champion, was also eliminated, losing to Kristina Mladenovic 6-2, 6-4.advertisementStepanek, the oldest man in the field at 37, hit 57 winners in his suspenseful encounter on Court Philippe Chatrier.Murray was leading 4-2 in the fourth set when play was suspended on Monday because of darkness. He was twice two points from losing while serving and trailing 5-4 in the fifth. But he held there, then broke Stepanek, and served out after wasting his first match point with a double-fault.”It’s unbelievable what he is doing,” Murray said. “At 37 years old, coming out and fighting like that. I don’t expect to be doing that myself at that age.”Murray, who will be 37 in eight years, progressed with Aljaz Bedene and Kyle Edmund to ensure three British men in the second round at Roland Garros for the first time since 1975.BERDYCH ADVANCESAlso advancing were seventh-seeded Tomas Berdych, No. 13 Dominic Thiem, No. 15 John Isner and No. 20 Bernard Tomic.Kerber received treatment on her shoulder during a changeover while trailing 3-0 in the deciding set.

Last week, she pulled out of the Nuremberg tournament because of her shoulder injury.”It’s getting worse and worse, but I hope it’s not too bad,” Kerber said.She’s the fifth Australian Open women’s champion to lose in the first round at Roland Garros, after Chris O’Neil (1978), Barbara Jordan (1979), Lindsey Davenport (2000), and Li Na (2014).Schiavone was surprised to receive a standing ovation after her loss, and was annoyed at tournament organizers for prematurely announcing this was her last French Open.”Roland Garros announced my retirement but I didn’t,” Schiavone said. “So you can stand up all of you and go back to work in the office because I didn’t say that. I will announce when I will want to stop.”Later, Serena Williams faced 77th-ranked Magdalena Rybarikova to start the defense of her title.The weather should remain dry, good news for tournament organizers who had a backlog of matches because of rain during the first two days.
