VIENNA -- Austrian tennis player Stefan Koubek, who was ranked a career-high No. 20 in 2000, has announced his retirement.
Currently ranked No. 261, Koubek will end his career with an exhibition match July 30.
"I wanted to play Roland Garros and Wimbledon one more time but I won't make it," he said. "Once you've decided to quit, you lose your motivation."
Kitzbuehel tournament organizers say the 34-year-old Koubek turned down a wild card for their ATP tour event in August.
Koubek won three ATP titles and has been part of Austria's Davis Cup team for 13 seasons.
