Japan's Naomi Osaka said she will skip next month's Billie Jean King Cup finals in Spain as she recovers from injuries that have kept her out of key tournaments during the WTA's Asian swing.
Osaka sustained a back injury during this month's China Open before skipping the Japan Open and the Pan Pacific Open.
"I thought I strained my back, but I did an MRI in Beijing," Kyodo News Agency quoted Osaka as telling reporters in Tokyo.
"I've played so many tournaments this year, so it was the toughest decision to not play this and not play BJK."
She recently began working with Serena Williams' former coach Patrick Mouratoglou after splitting with her longtime coach, Wim Fissette.
