Defending champion Serena Williams outplayed Poland's Agnieszka Radwanska in a one-sided semi-final match at the Australian Open on Thursday.

The world number one defeated Radwanska 6-0 6-4 in the Rod Laver Arena to reach the final, gunning for her seventh Australian title.

The 34-year-old will pay either Briton Johanna Konta or German Angelique Kerber in the final, looking to bring her grand slam tally up to 22.
