Sharapova pulls out of Miami Open after shoulder procedure

Maria Sharapova says she has undergone a “small procedure” on her right shoulder that will need a few weeks to heal, requiring her to pull out of next month’s Miami Open. Sharapova said she’s struggled since last summer with shoulder pain caused by a fraying tendon and small labrum tear. She tried unsuccessfully to solve the problem with exercise. She last won three matches at last year’s Australian Open.
