It was child's play again for Novak Djokovic on kid's day at the French Open yesterday, as the dominant Serb booked a third-round slot when Romanian Victor Hanescu retired hurt while trailing 6-4 6-1 2-3.
The 24-year-old took his winning streak from the start of the year to 39, but things could be about to get a little more serious for the world No 2 as he faces 2009 US Open champion Juan Martin del Potro next.
Third seed Roger Federer and last year's women's runner-up Samantha Stosur also found it easy on a hot and sunny day at Roland Garros with wins over France's Maxime Teixeira and Romanian Simona Halep respectively.
Del Potro, whose injury problems seem to be behind him, moved menacingly through with a straight sets victory over Slovenia's Blaz Kavcic.
Women's defending champion Francesca Schiavone of Italy looked impressive in brushing aside Russia's Vesna Dolonts 6-1 6-2, while the most dramatic match was saved until last when German Sabine Lisicki left Court One on a stretcher suffering from exhaustion after blowing a match point and crumbling to a 4-6 7-5 7-5 defeat by world No 3 Vera Zvonareva of Russia.
World No 1 Caroline Wozniacki also reached the third round but was given some anxious moments by Canada's Aleksandra Wozniak in a 6-3 7-6 victory.
Dark horse Julia Goerges of Germany, the 17th seed, had to battle hard for her 2-6 7-5 6-2 victory over Czech Lucie Safarova.
Other outsiders flew under the radar -- and quite fast. Spain's David Ferrer, seeded seventh, marched into round three by crushing Frenchman Julien Benneteau 6-3 6-4 6-2, while local favourites Gael Monfils, Jo-Wilfried Tsonga and Richard Gasquet all moved through in some style.
