Djokovic, Serena cruise as Kerber

Top seed Novak Djokovic launched his bid for a first French Open title with a routine victory while Serena Williams began the defence of her crown, but Australian Open champion Angelique Kerber crashed out on Tuesday.

Djokovic, a three-time Roland Garros finalist, faced little resistance from Taiwan's world number 95 Lu Yen-Hsun as he cruised to a 6-4, 6-1, 6-1 victory.

The Serb, bidding to become just the eighth man to secure a career Grand Slam, needed only 90 minutes on Court Phillipe Chatrier to book a second-round encounter with Belgian qualifier Steve Darcis.

"Well, second and third set were really good. I thought I found my rhythm. First set was up and down. But I'll take the positives out of it, and I'm hoping I can progress as the tournament goes on," said Djokovic.Serena Williams needed just 42 minutes to dispatch Slovakia's Magdalena Rybarikova 6-2, 6-0 as the American aims for another title that would see her equal Steffi Graf's Open era record of 22 Grand Slam wins.

"Today was great for me. I hope I continue to play like today, it's only the first round. I hope I win six more matches," said Williams, showcasing her French to an appreciate crowd. 

Andy Murray was forced to recover from a two-set deficit to overcome 37-year-old Radek Stepanek 3-6, 3-6, 6-0, 6-3, 7-5 in a match lasting three hours 41 minutes in total.

The second seed had been trailing by two sets to one but up a break in the fourth when play was suspended on Monday due to darkness.

The Scot duly returned to complete the job after making the crucial breakthrough at 5-all in the decider to set up a second-round encounter with 164th-ranked French wildcard Mathias Bourgue.

"He's always been extremely difficult to play," said Murray after a ninth career comeback from two sets down.

"He was playing drop shots, hitting the ball very flat, it was very difficult to get into a rhythm. That's credit to him and the way he played."While Murray toiled, there were no such problems for nine-time champion Rafael Nadal who extended his record at Roland Garros to 71 wins against just two losses.

The fourth-seeded Spaniard made quick work of 100th-ranked Sam Groth, taming the Australian's powerful serve with eight breaks in a resounding 6-1, 6-1, 6-1 win.

"It's obvious that was a good start for me," said Nadal. 

"I managed to break him very quickly. It was important because against such an opponent it's not easy to take his serve."

- Kerber dumped out -Kerber became the tournament's first major casualty as Dutchwoman Kiki Bertens consigned the German third seed to a 6-2, 3-6, 6-3 defeat.

"The first rounds are always tough in the tournament, especially for me, but, yeah, what can I say? It happens," lamented Kerber, who was hampered by an ongoing shoulder problem.

"She's a tough opponent. I was ready. But, yeah, at the end she made the important points."

Another former Melbourne champion, Victoria Azarenka, retired in her opening-round match with Italy's world number 118 Karin Knapp.Fifth seed Azarenka quit with a knee injury down 4-0 in the third set having already saved a match point in a second set tie-break.

Both Kerber and Azarenka were in Williams' section of the draw.

Sixth-seeded Frenchman Jo-Wilfried Tsonga strolled to a 6-3, 6-4, 6-4 victory against German qualifier Jan-Lennard Struff, with Tomas Berdych also cruising to a straight-sets win over Vasek Pospisil.

David Ferrer, the 2013 runner-up, thrashed Russia's Evgeny Donskoy 6-1, 6-2, 6-0.

Austria's Dominic Thiem struggled initially against Inigo Cervantes, dropping the opening set to the Spaniard, but the 13th seed rallied to claim a 3-6, 6-2, 7-5, 6-1 victory.

Thiem, who retained his Nice title over the weekend, is one of just three players alongside Nadal and Pablo Cuevas with multiple clay-court tournament wins this season.  John Isner fired 40 aces to advance 6-7 (4/7), 7-6 (14/12), 7-6 (9/7), 7-5 over Australian John Millman, while Bernard Tomic put recent struggles behind him to dispatch American Brian Baker in three sets.

Swiss eighth seed Timea Bacsinszky swept past Spanish lucky loser Silvia Soler-Espinosa 6-3, 6-1, while 12th seed Carla Suarez Navarro needed three sets to beat Czech qualifier Katerina Siniakova.

Seven-time major winner Venus Williams, who lost the 2002 final to sister Serena, edged out Estonia's Anett Kontaveit 7-6 (7/5), 7-6 (7/4), while 2008 champion Ana Ivanovic held off French wildcard Oceane Dodin in three sets.

Former runner-up Sam Stosur overcame Misaki Doi of Japan 6-2, 4-6, 6-3, but Francesca Schiavone, the 2010 champion, bowed out in straight sets to French 26th seed Kristina Mladenovic.
