Kim Clijsters continued her comeback from injury by easing into the last four at the Gaz de France Stars event.
The second seed swept past Bulgarian Magdalena Maleeva 6-3 6-4 and will face Russia's Elena Bovina, who beat Italy's Francesca Schiavone 7-6 (8-6) 6-1.
Top-seeded Russian Elena Dementieva beat Denisa Chladkova of the Czech Republic 7-5 6-4.
Dementieva will now play Italy's Maria Elena Camerin, who saw off Spain's Virginia Ruano-Pascual 5-7 7-5 6-4.
Clijsters beat Iveta Benesova on Wednesday as she made a winning return from the wrist injury which had kept her out for five months.
And the Belgian was backed by thousands of home fans in Hasselt as she raced into a 5-2 lead in the first set against Maleeva.
Clijsters then broke her opponent in the seventh game of the second set and went on to wrap up her sixth win out of six against the Bulgarian.
