Andy Murray cruises through at Miami Open

Andy Murray has defeated Denis Istomin 6-3 7-5 to book his place in the third round at the Miami Open.

It was a relatively straightforward outing for the world number two, who eventually won through in one hour and 38 minutes.

However, in the second set there was one moment of drama when Murray was broken by his Uzbek opponent while serving with a rogue ball from the women's event.

The Scot soon broke back, though, to seal his progression on the Atlantic coast.

Murray will now take on Bulgarian 26th seed Grigor Dimitrov for a spot in round four.
