Andy Murray powers on at Miami Masters

Andy Murray has progressed to round three of the Miami Masters with a comfortable straight-sets win against Australia's Bernard Tomic.

The British world number three saw off the world number 45 6-3 6-1 in 58 minutes.

Murray's reward for beating Tomic is a meeting with Grigor Dimitrov or Simone Bolelli.

The Scot's previous best at the tournament was last year when he lost in the final to Novak Djokovic.
