Radek Stepanek has called time on his playing career

Radek Stepanek has announced his retirement from tennis after a professional career spanning 21 years.

Together with Tomas Berdych, Stepanek led the Czech Republic to Davis Cup titles in 2012 and 2013, becoming the first player to win two decisive fifth rubbers in consecutive Davis Cup finals.

I have decided to end my career. I took a broader look at my life and found out I'd hate to risk my health. Radek Stepanek

The 38-year-old also won two Grand Slam doubles titles as well as five ATP singles titles, reaching a career-high of eighth in the singles rankings in 2006.

But Stepanek has also struggled with injury problems during his career and in the spring underwent lumbar spine surgery following his last appearance on the court at the Australian Open.

"I knew a tennis career was limited, but I wanted it to last as long as possible," he said. "I have fought until my last breath but it's time to go now.

"I've had some hard time in the year since the surgery.

"I have decided to end my career. I took a broader look at my life and found out I'd hate to risk my health."
