Serena Williams and Li Na swept past familiar foes at the Sony Open, setting up an exciting showdown for the Miami hardcourt crown between the world's top ranked players.
World number one Williams continued her utter domination of Maria Sharapova with a 6-4, 6-3 win over the fourth-seeded Russian, while second-ranked Li won a rematch of her Australian Open final, beating Dominika Cibulkova 7-5, 2-6, 6-3 to maintain her perfect record against the Slovakian.
A six-time Miami champion, the American's victory ran her winning streak against Sharapova to 15 matches, a stunning run that stretches back to 2004.
Li's mastery over Cibulkova may not span as many years but is no less complete, the Chinese veteran sweeping all seven of their meetings over a decade-long span.
Three of those wins have come this year, with Asia's first grand slam singles champion defeating the Slovakian in straight sets at Melbourne Park, in three sets at Indian Wells two weeks ago and now at Miami.
