Germany`s Kiefer retires to spend time with family
London: Former German number one Nicolas Kiefer announced his retirement from tennis on Thursday, saying he wanted to spend more time with his family.
The 33-year-old won a men`s doubles silver medal at the 2004 Olympics and clinched the last of his six ATP titles in 2000, the year in which he achieved a career-high world ranking of four.
"At the start of the New Year, you set yourself targets and I`ve achieved mine on Aug 11 of the year which is ending," Kiefer said on his website (nicolaskiefer.de).
"With the birth of our daughter Mabelle Emilienne, my greatest wish has been fulfilled. From now on, I would like to accompany and shape this new life.
"Therefore, after deep thought, I`ve decided to end my career as a tennis professional."
Kiefer looked on course to follow in the footsteps of six-times grand slam champion Boris Becker when he won the junior titles at the Australian and U.S. Opens in 1995.
But like many promising youngsters, he struggled to translate that success on the main tour and never managed to reach a final of a grand slam.
After reaching the Toronto Masters final in 2008, Kiefer struggled to shake off a wrist injury and as a result his ranking nosedived to 722nd in the world.
