Injury forces Murray to quit

Andy Murray suffered a birthday to forget as a wrist injury forced him to retire from his Hamburg Masters first-round match with Filippo Volandri.

The Scot, celebrating his 20th birthday today, was 5-1 up in the first set when he was left wringing his right wrist in intense pain after returning a powerful shot from the Italian.

The British number one had looked in far better form than last week, when he exited the Rome Masters at the first hurdle.

However, he was forced to quit the match two points after receiving treatment from the tournament physio and could now be a doubt for the French Open.
