Paris - French Open champion Li Na retired with a sore back against Tsvetana Pironkova in the second set of her opening match at the Open GDF Suez on Tuesday.

The third-seeded Li took a medical timeout while trailing 7-6 (7/5), 3-2 to have her lower back massaged by a physio and played a couple more points before retiring.

"I was feeling my back ... It was so painful," Li said. "That's why I called the physio to come to the court. I tried to tape and then tried to play the point, but it didn't work.

"I'll go to the hospital to take an MRI to see what happened."

Li rallied from a 5-0 deficit to force a tie-breaker but she then double-faulted at 3-2 to give Pironkova a mini-break. The unseeded Bulgarian took the first set on a forehand error from Li before jumping out to a 3-1 lead in the second.

"I played last week in the Fed Cup in Israel, I played some good matches which helped for my form and for my confidence," Pironkova said. "So I felt pretty good coming here and I'm glad I could show it on the court today against such a world class player."

German qualifier Mona Barthel and Petra Cetkovska of the Czech Republic also advanced to the second round. Barthel eased past Barbora Zahlavova Strycova of the Czech Republic 6-3, 6-2, and Cetkovska beat Italian lucky loser Alberta Brianti 6-3, 6-3.

Fourth-seeded Jelena Jankovic withdrew Tuesday because of a left thigh strain she picked up in Serbia's 3-2 win over Belgium in the Fed Cup last week.

"I was playing against (Kirsten) Flipkens and during one point in the second set, I felt a really sharp pain, but I managed to finish the match," Jankovic said.
