Novak Djokovic will face Britain's Andy Murray in the final of the Miami Open for a third time on Sunday after the pair triumphed in their semi-finals.

The pair have one win each against each other at Miami but Djokovic will be looking for a repeat of his Australian Open win over the Scot - and to improve his 17-8 career record against him. 

Third seed Murray delivered a controlled and precise performance to beat Czech Tomas Berdych 6-4 6-4 while Djokovic faced greater resistance in the form of big-serving American John Isner but still won 7-6(3) 6-2. 

The first set was on-serve throughout but the Serb emerged victorious from the tie-break and never looked back. 

The four-times Miami champion broke twice early in the second to open up a 4-1 lead and from then on the match was out of Isner's reach. The big-serving American was unable to create a single break point in the game but the 29-year-old, ranked 24th in the world, will be encouraged by his run to the last four. 

"It is always tough to play someone who serves that well, at times it is frustrating," said Djokovic.

Earlier, in bright sunlight and Floridian heat, Murray broke Berdych early in both sets and looked in charge throughout, winning 80 per cent of first-serve points while registering four service breaks.
