World number two Maria Sharapova eased past fellow Russian Ekaterina Makarova to reach her fourth Australian Open final in Melbourne.
Sharapova, the 2008 champion, needed one hour and 27 minutes to beat the 10th seed 6-3 6-2.
The second semi-final is an all-American contest between Serena Williams and Madison Keys.

Sharapova coped well on serve with a testing wind to improve her record against Makarova to 6-0 and close in on a sixth major title.
The 27-year-old saved two break points in a testing 10-minute opening service game before easing into a 4-1 lead.
Makarova, 26, hinted at a comeback when she broke for 4-3 but Sharapova responded immediately and served out the set after 48 minutes.
When she hammered away a backhand for the double break at 3-0 in the second, there was no way back for Makarova.
Sharapova made it six games in a row, saving two more break points at 4-1, to seal a place in her 10th Grand Slam final.
