Defending champion Rafael Nadal got his bid for a record-extending 12th French Open title off to the perfect start by brushing aside German qualifier Yannick Hanfmann, while world number one Novak Djokovic was also a comfortable victor in the first round at Roland Garros on Monday.

Serena Williams survived a first-set scare before defeating Russia’s Vitalia Diatchenko 2-6, 6-1, 6-0 to reach the second round.

The 37-year-old American, who is attempting to equal Margaret Court’s all-time record of 24 Grand Slam titles, racked up her 800th career main draw win with her victory in front of a half-full Court Philippe Chatrier.

Nadal, a 17-time Grand Slam champion, cruised to a 6-2, 6-1, 6-3 victory on the rebuilt Court Philippe Chatrier to set up a clash with another German qualifier —  world number 114 Yannick Maden — in round two.

Nadal raced into a 3-0 lead in the opening set before a second break of serve in the eighth game sealed it after just 40 minutes.

The second set was over in a flash as Nadal crushed nine winners past his beleaguered opponent. The winning line honed into view when Nadal broke after a lengthy game to take a 2-1 advantage in the third, and the Spaniard completed the job on his first match point as world number 184 Hanfmann blasted long.

Djokovic laid down an early marker in his bid to hold all four Grand Slam titles simultaneously for the second time, powering past Polish youngster Hubert Hurkacz. The 15-time major champion impressed in a 6-4, 6-2, 6-2 triumph and will face Swiss lucky loser Henri Laaksonen in round two.

Twelve months ago, Djokovic dropped out of the world’s top 20 after a shock quarter-final loss to Marco Cecchinato and even pondered skipping Wimbledon, but he has instead reclaimed his place at the top of the game.

Hurkacz had no answer to the 2016 French Open winner, as Djokovic sealed a second-round spot without breaking sweat, hitting 27 winners.

Later in the day, 23-time women’s major champion Serena Williams takes on Russia’s Vitalia Diatchenko.

Earlier on Monday, former world number one Caroline Wozniacki collapsed to a 0-6, 6-3, 6-3 loss to Russian world number 68 Veronika Kudermetova in the first round.

The Danish 13th seed had retired injured from her two previous matches in the lead-up to Roland Garros, and fell away badly after a strong first set.

Sixth seed and two-time Wimbledon champion Petra Kvitova was forced to pull out before her scheduled opener against Sorana Cirstea with a left arm injury, but said she should be fit for Wimbledon, which starts on July 1.

Dutch fourth seed Kiki Bertens looked in fine fettle, though, beating home player Pauline Parmentier 6-3, 6-4.

Elsewhere in the women’s draw, Australian eighth seed Ashleigh Barty saw off American Jessica Pegula 6-3, 6-3.

In the men’s event, three-time Grand Slam champion Stan Wawrinka progressed with a 6-1, 6-7 (3/7), 6-2, 6-3 win over Slovakian Jozef Kovalik.

Australian Alex De Minaur, seeded 21st, beat the United States’ Bradley Klahn 6-1, 6-4, 6-4, although Georgian 15th seed Nikoloz Basilashvili and Russian 12th seed Daniil Medvedev both exited the tournament.
