Paris: US Open champion Samantha Stosur had the honour of being the first player into the French Open second round at a sweltering Roland Garros on Sunday, brushing aside Britain's Elena Baltacha.

Australian sixth seed Stosur, the 2010 runner-up to Francesca Schiavone, took just a over an hour to see off the 68th-ranked Baltacha 6-4, 6-0 on Philippe Chatrier court.

The 26-year-old from the Gold Coast, who hammered 23 winners to Baltacha's eight, next faces either Irina Falconi of the United States or Romania's Edina Gallovits-Hall.

Joining Stosur in the next round was Russia's Svetlana Kuznetsova.

The 2009 champion, seeded 26 this year, marked her 40th Grand Slam appearance with a comfortable 6-1, 6-3 win over Croatian world number 117 Mirjana Lucic.

The 26-year-old Russian, who was also runner-up in 2006, brushed aside the 30-year-old Florida-based Lucic in just 61 minutes.

Kuznetsova tackles either Kateryna Bondarenko of Ukraine or Taiwan qualifier Chan Yung-Jan for a place in the last 32.

Czech 20th seed Lucie Safarova was also an early winner on the opening day, seeing off Anastasiya Yakimova of Belarus 6-2, 6-0.

Later Sunday, Venus Williams and Juan Martin Del Potro, whose careers have seen Grand Slam highs as well as injury-hit lows, will take centre-stage.

With top drawcards such as Novak Djokovic, Rafael Nadal, Roger Federer, Maria Sharapova and Serena Williams all being spared opening day duty at Roland Garros, the likes of Williams and Del Potro get an early chance to impress.

Williams, now ranked 53 in the world after battling energy-sapping Sjogren's Syndrome, was runner-up in Paris in 2002, losing the final to sister Serena.

The 31-year-old begins her 15th Roland Garros against Argentina's Paula Ormaechea.

Del Potro, the only man to have won a Grand Slam title outside of the 'big three' in the last seven years, begins against Spanish veteran Albert Montanes.

Ninth-seed Del Potro was a semi-finalist in 2009 before going on to win the US Open that year.

But a wrist injury saw him sidelined for nine months before his ranking slumped to 485.

Del Potro won the claycourt title in Estoril this year and could face Federer in the quarter-finals at the French Open.

Two other former champions are also in action on Sunday.

Juan Carlos Ferrero, the 2003 men's winner, faces France's Jonathan Dasnieres de Veigy while Ana Ivanovic, the 2008 women's champion, plays Lara Arruabarrena-Vecino of Spain.
