"I want to share with you one of the hardest decisions I have had to make in my life," Peer wrote on Facebook. "After 23 years, in which 13 of those years I was an international professional tennis player, I am retiring :-)
"I made this decision following a chronic inflammation in my shoulder, that has been lasting for over two years, and prevents me from competing at the high level that I am used to and expect from myself. At the same time, I lost my desire for the game of tennis and the intense way of life I have lived since I was 6.5 years old.
"I look back on this experience with a huge smile, a lot of happiness and satisfaction. I am proud of all of my accomplishments as well as the huge honor I was given to represent the state of Israel.
"I want to thank everyone for your never-ending support that I received every single day, every hour and every place I went to around the world. This Friday, 'Ulpan Shishi' on Channel 2 will broadcast a segment about my career, my deliberation about my retirement, and my plans for the future. I promise to continue to update you about every interesting development of Chapter 2 of my life."
After turning pro in 2004, Peer won five WTA titles and became the first Israeli woman to make the quarterfinals of a Slam, doing it twice in 2007. In 2008, she became the first Israeli ever to compete at a WTA tournament in the Arabian Peninsula at the Qatar Total Open.
In addition to her successful WTA career, Peer was a Fed Cup stalwart for Israel, playing over 75 matches and compiling at 45-31 record. In 2008 she represented Israel at her first and only Olympic Games in Beijing.
