PARIS: French Open dangerman Juan Martin Del Potro shrugged off a knee injury scare as well as sweltering 30-degree heat to reach the French Open second round today.
The ninth seeded Argentine, who made the semi-finals in 2009 before going on to claim the US Open title, saw off Spanish veteran Albert Montanes 6-2, 6-7 (5/7), 6-2, 6-1 in a shade over three hours. He will tackle France's Edouard Roger-Vasselin for a place in the last 32.
Del Potro, a potential quarter-final opponent of Roger Federer, had beaten Montanes in straight sets on his way to the Estoril title in April. But he endured a bumpy ride on Philippe Chatrier Court on Sunday when his troublesome left knee, which had already been taped, required further strapping at the end of the marathon second set.
The 23-year-old, the only man outside of Novak Djokovic, Rafael Nadal and Federer to win a Grand Slam title in the last seven years, also needed a doctor three games into the second set as the soaring temperatures threatened to take their toll.
Also making the last 64 on the opening day of the 2012 tournament was 2003 winner Juan Carlos Ferrero, who defeated French wildcard Jonathan Dasnieres de Veigy 6-1, 6-4, 6-3. Ferrero, playing in his 12th Roland Garros, next meets Croatian 21st seed Maran Cilic.
US Open champion Samantha Stosur had the honour of being the first player into the second round, brushing aside Britain's Elena Baltacha in her opener. Australian sixth seed Stosur, the 2010 runner-up to Francesca Schiavone, took just 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 Irina Falconi of the United States. Stosur, who also kicked-off the 2011 tournament, said she was getting used to the French Open Sunday starts which were introduced in 2006.
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 Lucic in just 61 minutes. Kuznetsova, also the 2004 US Open champion, next tackles either Kateryna Bondarenko of Ukraine or Taiwan qualifier Chan Yung-Jan.
