Host commentator Stuart Fraser: Job done, Andy Murray. He came out here knowing he had to win and he delivered. Getting it done in straight sets will also help too. All to play for in Group B on Thursday as Murray plays Federer and Raonic takes on Nishikori. Lot of qualification scenarios involved and I'm afraid it's a bit of a mathematical maze... Murray tells Sky Sports: 'It's nice. Last year was tough but I'm very happy to be back. The court atmosphere has been unbelievable. Nice match to look forward to against Roger now. Murray started the game off by answering a net call with one of his own and it proved too good for Raonic. More unforced errors from the Canadian made Murray's life easier before going to deuce.
