TOKYO (Reuters) - Wimbledon finalist Maria Sharapova, French Open champion Li Na and world number one Caroline Wozniacki will headline this year's Pan Pacific Open, Tokyo organizers said on Tuesday. Russian Sharapova, stunned by Czech Petra Kvitova in the women's Wimbledon final earlier this month, has twice won the $2.05 million Tokyo event, which begins on September 25. Sharapova and Danish rival Wozniacki, the defending champion, will fly to Japan early to take part in charity events in support of the victims of the deadly earthquake and tsunami on March 11. Organizers told Reuters, children would be invited from disaster-hit Fukushima Prefecture.
