Czech tennis star Berdych ends career

Czech player Tomas Berdych is retiring from tennis at the age of 34

Two-time Australian Open semi-finalist Tomas Berdych has retired from tennis and will make an official announcement at the ATP Finals in London on Saturday, his father has said.

Berdych's father, Martin, told the Czech paper Blesk on Wednesday about the decision which his son seemed to confirm in an online video, saying: "it was supposed to be a surprise."

The 34-year-old former world No.4 has recently suffered hip problems which kept him well away from the form with which he reached the Wimbledon final in 2010.

He reached the last four at Melbourne in 2014 and 2015, also making the semi-finals of the US Open in 2012 and the French Open in 2010.

In addition to winning 13 career singles titles, Berdych was Davis Cup champion with the Czech Republic in 2012 and 2013.
