Fourth seed Simona Halep only needed 53 minutes to beat Estonian Anett Kontaveit 6: 1 and 6: 1 and reach the semi-finals of the Australian Open on Wednesday.
Halep hadn't lost a set in their last two encounters with Kontaveit that only made a break on the serve of the former number one in the world rankings.
The Romanian, who finished second at Melbourne Park in 2018, will face Spaniard Garbine Muguruza on Saturday.
Garbine Muguruza stormed back to the Grand Slam with a 7: 5: 6: 3 win against Russian Anastasia Pavlyuchenkova and reached her first Australian Open semi-final on Wednesday.
The two-time Grand Slam winner will meet former finalist Simona Halep on Thursday after performing her most complete performance at a sun-kissed Rod Laver Arena in Melbourne Park this year.
The Spaniard Muguruza twice broke the 30th seeded Russian in the second set and crossed the finish line in a hail of winners. Pavlyuchenkova saved a match point with a hammering backhand, but was powerless when Muguruza sealed the match with a nifty drop volley.
