Hradecka had a poor first set versus Pennetta, who was coming off a 7-5, 6-3 win over Misaki Doi earlier Friday, but piled up five breaks -- four in the final set -- to gain a spot in the finals. Hradecka allowed Pennetta just four points on serve in the third set.
No. 3-seeded Alize Cornet earned a return to the Strasbourg International finals -- she lost to Francesca Schiavone in last year's title match -- by edging past Eugenie Bouchard 7-5, 6-7 (5-7), 6-3 in a 2 hour, 56-minute match.
She was on the court longer Friday than Hradecka, who played two matches, was.
Cornet, however, lost her serve just three times in the lengthy match and saved all six break points she faced in the third set.
Hradecka is 1-0 versus Cornet, having won a 2010 meeting but she's 0-5 in WTA finals. Cornet is 2-3 in title matches, with a win in Austria last June to her credit.
