Serena Williams embraces as she celebrates after victory in her women's singles semi-final match against Madison Keys.
Maria Sharapova has reached the Australian Open final for the fourth time, beating fellow Russian Ekaterina Makaraova 6-3, 6-2 in a lopsided semi-final.
Serena Williams weathered a barrage of big serves and heavy groundstrokes early and needed nine match points before beating Madison Keys 7-6 (5), 6-2 to set up an Australian Open final against second-seeded Maria Sharapova.
The second-ranked Sharapova needed 10 minutes to hold in her opening service game, fending off two break points.
Top-ranked Williams, bothered by a cold in recent days, dominated the second set of the all-American semi-final, breaking Keys' serve twice.
Sharapova won the Australia Open title in 2008 but was comprehensively beaten in the championship matches in 2007, by then unseeded Serena Williams, and in 2012 by Victoria Azarenka.
Williams, an 18-time major winner, is back in the final here for the first time since winning her fifth Australian title in 2010.
