Osaka on to semifinals at Pan Pacific Open

Naomi Osaka raised her game when she needed to, and it landed her a spot in the semifinals of the Pan Pacific Open in Tokyo. The U.S. Open champion, who upset Serena Williams in the final in New York earlier this month, won her ninth straight match Friday, beating Barbora Strycova 6-3, 6-4. Osaka will next face Camila Giorgi, who advanced after Victoria Azarenka retired from their match with an illness in the first set. Giorgi was leading 5-3 when it ended.
