World number one Novak Djokovic overcame an error-prone John Isner on Friday to join Andy Murray in the final of the Miami Open.

Djokovic prevailed 7-6 (7-3) 6-2 at the ATP 1000 event, as Isner produced 38 unforced errors in the semi-final, compared to just eight from the Serb.

It sets up a rematch of the 2009 and 2012 Miami Open finals, with Murray and Djokovic having split the two deciders in Florida.

Murray - the third seed - defeated Tomas Berdych 6-4 6-4 in Friday's other semi-final.

After a tight first set that included no breaks of serve, Djokovic took control in the second set against Isner when he broke the big American in the third game - the first time the 22nd seed had been broken for the tournament.

That would be the second of five straight games that Djokovic would win as he raced to a 5-1 lead, before serving out the match in the eighth game of the set.

The 27-year-old top seed hit fewer winners than Isner (25-29) in their 92 minutes on court, but Djokovic gave his opponent few free points on his way to his third final of 2015.

Djokovic defeated Murray in four sets in the Australian Open final in January, and in two sets in the semi-finals at Indian Wells last month.
