Sharapova advanced in 89 minutes against Kerber, whose move into the WTA top-10 on Monday will complete a line-up for 10 different nationalities at the summit of the women's game.

Li, who will defend her French Open title when the grand slam starts a week from Sunday, reached the title match without hitting a ball in her semi-final as opponent Serena Williams withdrew, claiming back pain but admitting the pullout was really just a precaution.u00a0
