FILDERSTADT (Germany), Oct 11: Daniela Hantuchova ended the run of American qualifier Alexandra Stevenson with a crushing 6-1 6-2 victory in the quarter-finals of the Porsche Tennis Grand Prix on Friday.

Stevenson, who stunned top seed Jennifer Capriati in the previous round, hit 11 double-faults, with four of those coming in just one game, and she never found her rhythm against a steady opponent.

Stevenson’s second double-fault allowed the eighth seed Slovak to break for 2-0, and some good returns from Hantuchova earned another break for 4-0.

Stevenson eventually held with an ace in the sixth game, and took advantage of two double-faults from Hantuchova to break for a 2-0 lead in the second set. But that was the only weak game from Hantuchova, who then took the next six games for an easy victory.

Swiss qualifier Myriam Casanova was also unable to follow up her second round upset of fourth seed Justine Henin when she was beaten 6-2 6-3 by Elena Dementieva.

The Russian sped to a 4-0 lead in the opening set as she opened up some winning angles in the hard-hitting baseline rallies.
