Federico Luzzi died suddenly in October at the age of 28, just a few days after being admitted to a hospital with an illness that was eventually diagnosed as leukemia. He reached a career high of No. 96 in 2001. Many players paid tribute to Luzzi upon hearing the news. "I got to train with Federico a few times, and I remember him as a great person, fun to be with and very Italian," said Rafael Nadal. "All of us who are here in Paris [at the Masters tournament] have been talking about it and all of us are in shock and very upset."
Daniela Klemenschits, who played doubles for Austria alongside twin sister Sandra, died in April at the age of 25 from a rare form of abdominal cancer. As a team, the two had been ranked in the top 100 and played Fed Cup for Austria before both were diagnosed with the illness last January. The WTA and its players contributed funds and held charity events to help pay for their treatment, raising a total of $70,000. By this summer, Sandra had recovered sufficiently to play doubles at the WTA event in Bad Gastein.
