Djokovic's superior fitness tells to reach Miami final
World number one Novak Djokovic showed his class by making it into the final of the Miami Masters, defeating Belgium's David Goffin 7-6 (7-5) 6-4 in a compelling last four contest.
In humid conditions in Florida, Djokovic displayed his legendary physical fitness to emerge trumphant, but Goffin certainly pushed him every step of the way.
Goffin actually was a break up in the first set at 4-3, but the Serb fought back before taking the opener in an entertaining tie-break.
The second set was slightly more comfortable for the 28-year-old as he closed the match out 6-4 with Goffin tiring towards the end.
"It was very warm, very humid," said Djokovic.
"But I was proud to stay tough in the important moments and come up with some big serves.
"It was not my best match but credit to David for hanging in there.
"He hit some lines at important moments and you need a bit of luck but it comes and goes both ways. I always try to make them play an extra shot when opponents attack me."
Djokovic will meet either Japan's Kei Nishikori or Australia's Nick Kyrgios in tomorrow's final.
