Second round of action at the 2012 French Open continued Thursday. No. 10 John Isner provided the highlight of the day with another marathon match against a Frenchman. Unlike his famous 2010 match at Wimbledon against Nicolas Mahut, Isner ultimately lost, 6-7 (2), 6-4, 6-4, 3-6, 18-16, to Paul-Henri Mathieu. The match was the second longest in French Open history, lasting five hours and 41 minutes.
Also on the men's draw, No. 5 Jo-Wilfried Tsonga of France needed four sets to take out Germany's Cedrik-Marcel Stebe, 6-2, 4-6, 6-2, 6-1. Tsonga broke his opponent nine times in 15 chances during the match.
On the women's draw, two Americans advanced. Varvara Lepchenko won a hard-earned upset victory over No. 19 Jelena Jankovic, 7-6 (11), 4-6, 6-4. Christina McHale, meanwhile, had no trouble with fellow American Lauren Davis, winning 6-1, 6-3.
Due to the drawn out battle between Isner and Mathieu, the evening match between No. 2 Maria Sharapova and Ayumi Morita was postponed until Friday.
