Daniela Klemenschits has died

25-year-old Daniela Klemenschits, who--along with her twin sister, Sandra--was diagnosed last year with a rare form of abdominal cancer, has died.

The Klemenschits twins reached the finals of Istambul in 2005, and the semifinals of both Stockholm and Budapest, also in 2005. When they were on the ITF circuit, they won twenty doubles titles.

Klemenschits was also a member of the Austrian Fed Cup team in 2005. Her sister is reported to be recovering.
