Li Na vows to learn from losing streak

China's Li Na has vowed to learn the lessons from her defeats as her post-Australian Open misery continued on Wednesday when she exited Stuttgart's WTA tournament in the second round.

The 29-year-old sixth seed lost 6-4, 7-5 to Germany's Sabine Lisicki to suffer her fifth defeat in six matches since losing the Australian Open final to Kim Clijsters in January.

Since her Melbourne loss, Li suffered defeats in her opening matches at Dubai, Doha, Indian Wells and Miami, despite holding match points in two of those defeats.

She beat Latvia's Anastasija Sevastova in Monday's first round match here to stop the rot, but was then beaten by Lisicki in the second round, but has vowed to learn from her mistakes.

She will now play at the Madrid and Rome tournaments in the coming weeks in preparation for the French Open.

"It was a difficult and tough match," she told AFP. "Of course, it's always hard to play against a player from the host country."

"I wasn't feeling too bad out there and the French Open is still a month away."

"I feel good and I need to go away and learn the lessons from this week and move forward."
