A file picture dated June 7, 2008 shows Ana Ivanovic of Serbia celebrating with the trophy after winning the French Open tennis tournament at Roland Garros in Paris, France.  The former world no. 1 retired from tennis yesterday (December 28) at age 29, because she can no longer play at the highest level due to injuries. In a live broadcast on Facebook, Ivanovic said: ‘‘It was a difficult decision, but there is so much to celebrate.’’ The Serb won 15 tour titles, including the 2008 French Open, and is now ranked No. 63.
