Novak Djokovic makes winning start with new coach Andre Agassi

Agassi has been tempted into coaching for the first time by the defending French Open champion but must leave Paris well before the tournament finishes. "She has spectacular body, also, to be able to do that". Raonic fired 15 aces and 44 winners to book a meeting with Brazil's Rogerio Dutra Silva, who saved two match points before overcoming Mikhail Youzhny of Russian Federation in five sets. I am very happy the way that I arrived here.

The 25th-seeded Johnson won 6-3, 6-3, 6-7 (4), 6-7 (3), 6-3.

For Agassi it was a successful, if not entirely comfortable, return to the court where he completed his career Grand Slam in 1999.

"It's of course very frustrating every time I play against Nadal I think that I have missed something, so there are quite a lot of regrets there".

"Pretty huge disappointment, especially on a surface I really enjoy playing". Was not an easy opponent in the first round, obviously. "I'm feeling good, I'm playing good tennis and I'm happy to be back in Paris".

Elsewhere, Canadian fifth seed Milos Raonic beat Belgium's Steve Darcis 6-3 6-4 6-2.

"The match I played was good".

Kristina Mladenovic and Garbine Muguruza have also reached the second round.

Muguruza, who stunned Serena Williams in last year's final, triumphed 6-2, 6-4 to set-up a second round clash with Anett Kontaveit of Estonia.

An unexpected rash of errors early in the second set allowed Paire into the match, and the world number 45 had a break point to lead 5-3, but Nadal snuffed out the danger and powered home.

Del Potro's best result at Roland Garros is the semifinals in 2009, the year he won at Flushing Meadows.

Title-holder Djokovic strolled through his opener against Marcel Granollers of Spain, advancing 6-3, 6-4, 6-2. The 20-year-old Zverev defeated Djokovic in Rome a week ago to become the first player born in the 1990s to land a Masters title.

With the crowd slowly getting on his side, it looked like we might actually have a proper contest here in the first round at the Suzanne-Lenglen, but you knew Nadal, looking for a record tenth French Open title, was going to break back immediately, didn't you. "Then he has to leave, because he has already scheduled some things that he can not reschedule", Djokovic said.

The showdown of the day should be 15th-seeded Gael Monfils of France against Dustin Brown of Germany.

In the women's draw, No. 3 Simona Halep is up against Jana Cepelova, and No. 5 Elina Svitolina plays Yaroslava Shvedova.

Under a hot sun, Djokovic was in a joyful mood on the showcase Philippe Chatrier court.
