Italy has booked a place in the Davis Cup final against Australia after a stunning 2-1 come-from-behind win against Novak Djokovic's Serbia on Saturday.
Young gun Jannik Sinner led his nation to victory, saving three match points against Novak Djokovic before defeating the world no.1 6-2 2-6 7-5 and avenging his loss to the legend in the recent ATP Finals.
After Lorenzo Musetti was beaten by Miomir Kecmanovic in three sets 6-7(7) 6-2 6-1, it was up to Sinner to beat Djokovic to keep Italy in the tie to reach Sunday's final (Monday AEDT).

Sinner had only beaten Djokovic once in their five encounters - at the recent ATP Finals in the round-robin stage - before he lost to the Serbian in the final of the same event.
It was a comfortable first set for the Italian, who broke Djokovic in the third and fifth games before claiming it 6-2.
But as nearly always, Djokovic fought back when down to snare the second set 6-2 and take all the momentum into the decider.
The third set remained on serve until the 10th game, with Sinner falling to 0-40 at 4-5 on his serve and facing three match points that would send Serbia into the final.
However, the world no.4 saved all three, retained his serve, before breaking Djokovic in the following match and then serving it out 7-5.
The tie was then to be decided by the doubles match-up with both teams sending out their big guns - Serbia with Djokovic and Kecmanovic and Italy with Sinner and Lorenzo Sonego.
In a tight contest, a single break saw the first set head to the Italian pair 6-3, before early breaks were traded in the second.
But the seventh game went the Italians way before they eventually served out the set 6-4 to earn a spot against Australia in the final.
Italy will be favourites for the final with fourth-ranked Sinner leading the charge, while the second singles player will be out of Musetti (world no.27) and Sonego (world no.47).
Australia's team is spearheaded by Alex de Minaur (world no.12), with Alexei Popyrin (world no.40) likely to play singles ahead of Jordan Thompson.
It's in the doubles where Australia holds a key advantage with Wimbledon 2022 winners Matt Ebden and Max Purcell expected to be favourites if the tie extends to the decider.
