World number one and defending champion Novak Djokovic will face Japan's Kei Nishikori in the ATP and WTA Miami Open final after straight-set triumphs on Friday in which both were tested.
Djokovic, an 11-time Grand Slam champion whose three titles this year include the Australian Open, downed Belgian 15th seed David Goffin 7-6 (7/5), 6-4.
The 28-year-old Serbian will try to match the career record of six Miami crowns won by Andre Agassi by capturing his third consecutive title at the hardcourt event. Sixth seed Nishikori, the 2014 US Open runner-up, downed Australian 24th seed Nick Kyrgios 6-3, 7-5.
Djokovic has a 6-2 career edge over Nishikori, including five wins in a row, most recently in this year's Australian Open quarter-finals.
Djokovic won his 15th consecutive Miami match and the 29th of his past 30, but only after winning a tense tie-breaker and taking the lone break of the second set, prompting a post-match kissing of the court.
Djokovic improved to 27-1 on the season, which has included his 11th career Grand Slam title and crowns at Doha and Indian Wells.
He could claim the Miami-Indian Wells double for the third year in a row and his 63rd career title on Sunday.
Squared 4-4 in the tie-breaker, Goffin hit an overhead smash that Djokovic sent back as a lob inside the far baseline to keep the point alive and later took full advantage by winning it with a forehand drop volley winner.
Goffin, who will jump to a career-best 13th in next week's rankings, hit a forehand wide to give Djokovic two set points, then saved one on a drop volley winner but lost the set when the ball deflected off the edge of his racquet as he leaped to reach another Djokovic lob.
In the second set, Goffin netted a backhand to hand Djokovic a break for a 4-3 edge and the world number one held twice to triumph after two hours.
Djokovic has reached the final in 19 of his past 21 events and in 11 consecutive ATP Masters Series events. He could win a record 28th ATP Masters crown, surpassing the mark of Rafael Nadal.
Nishikori broke Kyrgios for a 2-1 edge and held from there, claiming the first set after 29 minutes when the Aussie double faulted away a break.
After an early exchange of breaks, the second set was decided when Nishikori broke in the last game on a wild point. Nishikori raced to the net to save a ball off the net cord, Kyrgios fired back two tricky returns and Nishikori finally won with a crosscourt forehand volley. Nishikori, who won his fourth consecutive Memphis title in February, reached his second ATP Masters final, the other coming in 2014 at Madrid.
