PARIS (AFP) - Top seed Dinara Safina enjoyed another French Open breeze on Wednesday, defeating teenage compatriot Vitalia Diatchenko 6-1, 6-1 to set up a last-32 clash with another Russian, Anastasia Pavlyuchenkova.Safina, who didn't lose a game in her first round mauling of Britain's Anne Keothavong, took just 55 minutes to dispose of 18-year-old qualifier Diatchenko, the world number 151.The world number one next faces 17-year-old Pavlyuchenkova, the 27th seed, who reached the last 32 with a 6-2, 7-6 (7/2) win over France's Julie Coin. "I played a good match today. She is very young and maybe was a little threatened," said Safina. "It should be a great match against Pavlyuchenkova. She's having a great season. I've never played against her or practised with her so I'm looking forward to meeting her." Wednesday's win was Safina's 16th in her 17 matches since she became world number one in April. Also progressing to the third round were Belarusian ninth seed Victoria Azarenka and Chinese 25th seed Li Na. Defending champion Ana Ivanovic was later facing Thai veteran Tamarine Tanasugarn and third-seeded Venus Williams was due to meet Lucie Safarova of the Czech Republic, while former world number one Maria Sharapova was up against 11th-seeded countrywoman Nadia Petrova. Later Wednesday, four-time champion Rafael Nadal tackles Russia's Teimuraz Gabashvili looking for a place in the last 32 as well as another mark in the record books. If the world number one prevails he will beat Chris Evert's record of 30 successive wins at Roland Garros. Evert set her sequence between 1974 and 1981, although she didn't play from 1976-1978. France's Fabrice Santoro, playing his 20th and last Roland Garros, was beaten 6-3, 6-1, 3-6, 6-4 by Belgium's Christophe Rochus in a first-round match held over from Tuesday because of bad light. Britain's Andy Murray, the third seed, was playing Itay's Potito Starace.
