LONDON - Judy Murray has given up her role as captain of Great Britain's Fed Cup team, the Lawn Tennis Association announced Tuesday. Murray, the mother of British tennis star Andy Murray, was appointed to skipper the side in the Fed Cup -- the leading women's international team tennis tournament -- in 2011. But while Andy led Britain to victory in last year's Davis Cup, the men's equivalent, Judy was unable to have anything like the same impact from off the court, with her side failing to gain promotion to the elite World Group from the Europe/Africa zone. Judy Murray recently became a grandmother for the first time following the birth of Andy's daughter Sophia last month and has been heavily involved in various schemes to promote grassroots tennis in Britain.
