Jankovic reaches 4th round at French Open
Tenth-seeded Jelena Jankovic defeated Bethanie Mattek-Sands of the United States 6-2, 6-2 to advance to the fourth round of the French Open on Friday.
Jankovic, who reached the semifinals at Roland Garros in three of the last four years, broke twice in each set and didn't face a single break point.
The Serb will next play defending champion Francesca Schiavone, who advanced when Peng Shuai retired while trailing 6-3, 1-2.
Mattek-Sands, one of the two remaining American players in the women's draw with Vania King, had 30 unforced errors and received treatment on her right ring finger at 1-1 in the second set.
