Top seed Samantha Stosur is through to the last four of the Hobart International after a comfortable win over Bojana Jovanovski.
Home favourite Stosur had looked out of sorts in the early rounds but she was simply too strong for the eighth seed from Serbia as she raced to a 6-3 6-2 victory.
The former US Open champion will now face seventh-seeded Klara Zakopalova in the semi-final.
Zakopalova, who reached No 20 in the world rankings last season, held her nerve to win the first set before recovering to rattle off five games on the bounce in the second to clinch a 6-4 7-5 victory.
Estrella Cabeza Candela recovered from a slow start to beat Monica Niculescu 3-6 7-6 (7-3) 6-4.
Cabeza Candela will face fellow Spanish qualifier Gabrine Muguruza in the semi-finals after she shocked second seed Kirsten Flipkens 6-4 6-3.
