Cornet, who ousted Euginie Bouchard en route to the semi final, lost the opening set 6-1 before winning the second 6-3 and reversing the opening set scoreline in the decider to advance.
And Hradecka overcame the much fancied Flavia Pennetta, also in three sets, to seal her place in the final.
In the other WTA women’s event in Brussles on Friday, Jamie Hampton advanced to the semi final with a 5-7 6-3 7-5 victory over second seed Roberta Vinci and Kaia Kanepi beat Varvara Lepchenko, also in three sets.
