Sharapova fires coach after losing to 44th-ranked player
Following her loss to 44th-ranked Naomi Osaka, Russia's Maria Sharapova has parted ways with her coach Sven Groeneveld. Sharapova, who registered her third consecutive loss for the first time since 2003, had been working with Groeneveld for over four years. The former world number one, who returned from a 15-month ban last year, is currently ranked 41st in the world.
