Caroline Wozniacki says that she wrote to WTA CEO Stacy Allaster about the Linz tournament awarding Angelique Kerber a late wild card. The top-seeded Kerber won the Linz title and by reaching the semifinals there secured the final spot at the upcoming WTA Championships in Istanbul, knocking the Dane out of the competition.

Wozniacki, who will likely be an alternate at the year-end event, says Allaster has yet to answer her formal complaint.

“I do not understand that you can suddenly change the draw and allocate of wild cards that way,” Wozniacki told Ekstra Bladet. “I wrote to Stacey, but I have not got a proper answer."

Wozniacki is a member of the WTA Player Council.

A WTA source tells TENNIS.com that the tournament's action was in accordance with WTA rules. Kerber was able to secure the wild card when world No. 337 Lisa-Maria Moser of Austria withdrew and gave her wild card back for “personal reasons.”

Former No. 1 Wozniacki missed qualifying for the WTA Championships for the second straight year.

“Of course it is a shame not to [make Istanbul],” Wozniacki said.

The world No. 9 also told the newspaper that various reports in the British press that she has split with her long time boyfriend Rory McIlroy were untrue.

“I'm so tired of the rumors,” she said. “They occur every time Rory and I are apart a few days or do not write on Twitter. There is nothing in it, and from now on I just think that I will keep my private life private... All is well, and there's not much more to say about it. I just want to be allowed to live my life off the court without all the speculation."
