Maria Sharapova cruised into the second round of the French Open with a 6-1 6-2 victory over fellow Russian Ksenia Pervak.
Rain in Paris held up play for an hour, and that was almost exactly the time it took Sharapova to dispatch Pervak on a damp Court Philippe Chatrier.
The 27-year-old has grown to like clay and, until she lost to Ana Ivanovic in Rome, she had not been beaten by anyone on the surface except Serena Williams since the French Open in 2011.
Williams was the player who ended Sharapova's hopes of retaining her title 12 months ago with victory in the final, and they could meet again in the quarter-finals this time.
Qualifier Pervak was never likely to trouble the seventh seed and she did not hold her serve during the first set.
Pervak managed to end that sequence at the start of the second but Sharapova then reeled off five games in a row and wasted no time clinching victory.
In the second round, Sharapova will play Bulgaria's 2010 Wimbledon semi-finalist Tsvetana Pironkova.
"First matches at Grand Slams are always tough, no matter how prepared you are, no matter how many matches you've played," said Sharapova, now 13-1 on clay in 2014 with titles in Stuttgart and Madrid.
"There is always a bit more tension in that type of Grand Slam atmosphere. It's certainly more special, especially when you walk out on court."
Dominika Cibulkova, the Slovak ninth seed, beat France's Virginie Razzano 7-5 6-0 and Italian 12th seed Flavia Pennetta eased past Austria's Patricia Mayr 6-2 6-2.
Fifth seed Petra Kvitova was a straight-sets winner, while Eugenie Bouchard made a fine start to her tournament with a 6-0 6-2 thrashing of Shahar Peer.
German 16th seed Sabine Lisicki, last year's Wimbledon runner-up and who is coached by former world No 1 Martina Hingis, defeated French wildcard Fiona Ferro 6-1 7-5.
Also going through was Austria's Tamira Paszek whose 6-2 7-6 (7-5) win over Belgium's Alison van Uytvanck was her first at Roland Garros for seven years.
