Every once in a while, Jelena Jankovic's back goes out on her during a match. It happened today, while she played Jelena Dokic in the second round of the U.S. Open. Jankovic had treatment for the injury, but it was obvious that her movement was hampered. She also had some help from her opponent, who double-faulted fifteen times. Jankovic won in straight sets, and she has a day to get some rest and some more treatment, but the recurrence of the injury is troublesome.
It was a pity that there wasn't more of a crowd around to watch Francesca Schiavone this morning. The 7th seed put on a serving show, and defeated Mirjana Lucic 6-1, 6-1. Top seed Caroline Wozniacki very easily defeated Arantxa Rus in the night match, and 2004 champion Svetlana Kuznetsova defeated Elena Baltacha. 31st seed Kaia Kanepi went out to Silvia Soler-Espinosa, and Carla Suarez Navarro (from whom we haven't heard in a while) defeated Simona Halep, the player who upset Li Na.
There was a big comeback today, too. Down a set and 0-3, Andrea Petkovic won seven straight games and eventually prevailed over Zheng Jie. It was a really good match, and it gave us even more evidence that Petkovic has made a lot of progress in the mental part of her tennis. She's dealing with a meniscus tear right now, and reports that--while the pain is occurring less frequently--it takes her by surprise and makes her afraid to move sometimes.
