World number one Novak Djokovic reached the final of the Miami Masters, defeating Belgium's David Goffin 7-6 (7-5) 6-4 in a hard-fought semi-final.
Goffin broke for 4-3 in the first set, but the Serb hit straight back to level and took the tie-break 7-5.
Djokovic, 28, increased the pressure on Goffin in the second set, breaking for 4-3 and closing out comfortably.
He will meet either Japan's Kei Nishikori (seeded sixth) or Australia's Nick Kyrgios (24) in Sunday's final.
Both players were tested physically by the Florida heat and humidity, and Djokovic's superior fitness eventually told.
