Andy Murray overcame a poor start to secure his place in the fourth round of the Miami Masters thanks to a 7-6 (7-3) 6-3 win over Grigor Dimitrov.
The British number one looked out of sorts early in the first set and was broken twice as his Bulgarian opponent streaked into a 5-2 lead.
Murray rallied, however, and saved two set points before the world number 32 threw down three double faults to hand his opponent a route back into the game.
The US Open Champion served out to set up a tie-break and took it without much fuss to three.
Dimitrov could not reproduce his early form and looked in trouble as he was broken in the first game of the second set.
Murray clinched the match simply enough and will play Italian world number 19 Andreas Seppi in the fourth round.
While the Italian should pose a greater examination than Dimitrov, Murray will be expected to make the fifth round as he has a 4-1 record in favour from the pair’s previous meetings.
Should the second seed make it past Seppi, a tough match up awaits as Jo-Wilfried Tsonga and Marin Cilic will fight it out for the other sport.
Murray and Seppi will play their fourth round clash on the evening of Tuesday March 26.
