Tianjin - Top-seeded Jelena Jankovic overcame a second-set lapse to defeat Russian Alla Kudryavtseva 6-2, 0-6, 6-0 in the first round of the Tianjin Open on Tuesday.
Jankovic was broken three times in the second set, winning only four points on her serve, but came back to break Kudryavtseva three times in the third.
Crowd favorite Peng Shuai, who grew up in Tianjin, also struggled, needing three sets to defeat Shahar Peer of Israel 7-5, 4-6, 6-2.
