Shanghai - Novak Djokovic survived 55 unforced errors and missed 11 break points but scratched out a 4-6, 6-3, 7-5 win over Gilles Simon on Saturday to move into the final of the Masters Cup.
Djokovic took treatment in the third set for a left calf muscle pull as he denied the dream of year-end debutant Simon, who claimed the last of the spots in the eight-man field when Rafael Nadal withdrew.
"It's the Masters Cup, best eight players in the world this year are here, it's a huge success for me to reach the final," said the Serb.
"My injury is nothing too serious. It was just cramping because of a lot of running and a lot of rallies we had. So I just had to treat it a little bit in order to end up the match."
