Wozniacki reaches Luxembourg semis

The top seed claimed the opening set before her Serbian opponent battled back to force a decider.

Though at times she appeared to be on the ropes, Wozniacki rallied well to clinch a 6-3 3-6 6-3 win and set up a last-four showdown with Sabine Lisicki who beat Karin Knapp 7-5 4-6 6-0.

The other semi will be contested by Swiss Stefanie Voegele, who upset American second seed Sloane Stephens 6-3 3-6 6-2, and Germany’s Annika Beck, who saw off Katarzyna Piter of Poland in another three-set quarter-final which included two tie-breakers.
