( CNN ) -- Novak Djokovic extended his winning run to 23 matches with a 6-3 6-1 victory over American Mardy Fish to reach the final of the Masters 1000 tournament in Miami Friday . The Australian Open champion will play either Rafael Nadal or Roger Federer , who were playing in the night session , in Sunday 's final . The Serbian beat world number one Nadal to claim the prestigious Indian Wells crown last month . The world number two saved two break points as Fish made a strong start , but after a brief rain delay it was Djokovic who seized the initiative with an immediate break of service . `` I told Mardy at the end I got saved by the rain , '' Djokovic told the official ATP Tour website . `` It really seemed like that . After I went back to the locker room I had 45 minutes to get it together and I felt much better after I came back to the court . '' 14th seed Fish , who has succeeded Andy Roddick as the highest placed American in the rankings , was unable to respond as Djokovic closed out the opening set . He was broken immediately at the start of the second set and a further break in the fifth game left him no way back . The 23-year-old Djokovic eventually closed out victory in just 90 minutes as he continued his superlative start to 2011 . In other tennis news Friday , Britain 's Andy Murray has confirmed that doubles specialist Ross Hutchins will be his new coach from the Barcelona Open later this month . Murray , who was beaten by Djokovic in the Australian Open final , has gone out in the first round of his last three tournaments since the grand slam . The world number five has been without a coach since parting company with Miles Maclagan in July of last year .
