Five-time Grand Slam winner Maria Sharapova suffered a shock defeat on Wednesday to Japanese No. 1 Naomi Osaka, losing her opening match at the WTA Indian Wells tournament 6-4, 6-4. The former world number one, and twice a winner in the California desert, Sharapova was one of the tournament's major attractions after missing the last two events. "I wanted to do well here and not just because I won this event a couple times," Sharapova said.
