Andy Roddick ready to take part in London finale

Andy Roddick has secured his place at the ATP World Tour Finals in London next month.

Despite being forced out of the Shanghai ATP Masters 100 last week due to a knee injury, the American has won enough points to guarantee his spot at the 02 Arena.

Roddick becomes the sixth singles qualifier for the season's climax - held from November 22-29 - after retiring in his second-round clash with Stanislas Wawrinka in China.

And he is now relishing a return to London.
"The reaction I received from fans after the Wimbledon final was something I will never forget," he said.

"I've always had great support in London and I'm looking forward to being back there in November. I'm sure it will be a fantastic event."
