Five-time champion Serena Williams wasted no time booking her berth in the WTA Miami final by steamrolling Agnieszka Radwanska 6-0, 6-3 to set up a title clash with third seed Maria Sharapova.

Russia's Sharapova, a four-time runner up in Miami, was equally dominant as the newly-crowned Indian Wells winner hammered Jelena Jankovic 6-2, 6-1 in the other semi-final on Thursday.

Williams is bidding to become just the fourth woman in the modern era to win the same event six times, joining Chris Evert, Steffi Graf and Martina Navratilova.

Sharapova is in her fifth final in quest of her first Miami title.

Sharapova is also trying to become just the third woman to win both major March events, Indian Wells and Miami, in the same year.AFP
