For the second match in succession Novak Djokovic survived an Italian Open dogfight yesterday, this time beating big-serving Canadian Milos Raonic 6-7 7-6 6-3 to reach the final.

Djokovic, who won a sizzling quarter-final against Spain’s David Ferrer, was subjected to an onslaught of power by Raonic but eventually got the upperhand to book a final against top seed Rafa Nadal who last night overcame Bulgarian Grigor Dimitrov 6-2 6-2.

In the women’s event Sara Errani became the first Italian to reach the final in nearly 30 years after she saw off Serbia’s twice former champion Jelena Jankovic 6-3 7-5 in front of a passionate crowd at the Foro Italico.

“The crowd was a motivation for me, they were unbelievable,” said Errani, who will have to beat world no.1 Serena Williams, who saw off Ana Ivanovic 6-1 3-6 6-1, today if she is to go one better than compatriot Raffaella Reggi in 1985.

Djokovic was involved in another punishing match against the 23-year-old Raonic – a clash of styles lasting exactly three hours.

He started in low-key fashion as Raonic unleashed serves at 230km/h.

The 26-year-old looked to have the first set sewn up when he won the first three points in the day’s first tiebreak, only for Raonic to fire back with an incredible six-point streak on his way to sealing an opening set in which he flung down eight aces.

Djokovic was in the box seat in the second set when he finally broke Raonic’s serve in the fourth game after an hour and 42 minutes, only for the Canadian to break right back in a game that contained an improbable backhand drop shot.

The set drifted to another tiebreak, and despite Raonic fighting back from 2-0 down, Djokovic held his nerve to take it 7-4 and set up a decider.

Raonic dropped serve immediately in the third and that spelled the end of his challenge as Djokovic moved through to the final.
