Defending champion Francesca Schiavone bounced back to her winning ways at the French Open, beating Melanie Oudin 6-2, 6-0 Monday to advance to the second round.
Schiavone, who last year became the first Italian woman to win a Grand Slam singles title, won four straight games in the first set after being broken early by her 19-year-old American opponent. Schiavone, who had 25 winners to Oudin's six, then won seven straight games to advance.
Top-ranked Caroline Wozniacki will also play on the second day of the tournament. The Dane was to face 40-year-old Kimiko Date-Krumm of Japan.
The French Open is the only one of the four Grand Slam tournaments to begin on Sunday, and not everyone likes it all that much.
''It's very weird playing on Sunday,'' said 13th-seeded Svetlana Kuznetsova, the 2009 champion who reached the second round by beating Magdalena Rybarikova of Slovakia 6-2, 6-3.
''For me, it's the first time. But I believe it's more money to Grand Slam so it's more spectators, probably.''
Besides Kuznetsova, 2010 finalist Sam Stosur advanced on a warm day in Paris. The eighth-seeded Australian was broken in the opening game, then had little trouble beating Iveta Benesova of the Czech Republic 6-2, 6-3.
Stosur also thought it was strange to start on Sunday.
''It's just different,'' Stosur said. ''You've got an extra day, but I think with all the others not doing it, it definitely is a bit of, not a shock, but it's just weird knowing that, OK, my tournament starts on Sunday and then I think you get two days off now.''
No. 10 Jelena Jankovic of Serbia, No. 14 Anastasia Pavlyuchenkova of Russia, No. 17 Julia Goerges of Germany, and No. 32 Tsvetana Pironkova of Bulgaria also advanced.
Two seeded women lost, No. 19 Shahar Peer of Israel and No. 18 Flavia Pennetta of Italy, and one man, No. 19 Marin Cilic of Croatia.
