Andy's Defence

Andy Murray will begin his defence of one of the biggest titles of his career next week as the Sony Ericsson Open gets underway in Miami. The Brit defeated current world number two Novak Djokovic to win the trophy last year, the result being that he heads to Crandon Park with serious ranking points to defend. And with the rest of the world's top 10 entered (minus Nikolay Davydenko) it's looking tough.
