The latest of goals from Andrea Pirlo secured a dramatic 2-1 Serie A victory for Juventus and denied Torino a rare point from the Derby della Mole.
Lowly Torino were much the better side across town at the Juventus Stadium and, after going behind to an early Arturo Vidal penalty, hit back with a sensational goal on the run from Bruno Peres.
With a first derby win since 1995 within their grasp, the visitors turned the screw throughout the second half and were given a late boost when Juve full-back Stephan Lichtsteiner was sent off.
However, deep into stoppage time, Pirlo broke Torino fans' hearts with a fiercely-driven winner.
Having failed to secure a point from the derby since 2008 - they had not even scored against their city rivals in 12 years - Torino set themselves up to remedy at least one part of that unhappy streak.
Their two former Juve strikers, Amauri and Fabio Quagliarella, would prove a real handful to their one-time employers and the latter tested Marco Storari with a dipping free-kick early on.
The award of a penalty kick against them was not part of the plan, however, and Vidal made no mistake from the spot after Omar El Kaddouri appeared to stop Pirlo's cross with his arm.
Torino's response to the setback was remarkable and saw Peres notch the club's first goal against Juve since Benoit Cauet's back in February 2002.
It was a stupendous individual effort, too, as the Brazilian right-back took on an entire team, streaking past the likes of Paul Pogba and Patrice Evra before confounding Storari with a perfect angled drive.
With Juve left stunned, Torino looked to snatch the lead before the break and Amauri might have turned the game on its head with his attempt from close range, but his accuracy let him down.
The final chance of the half did fall to Juve and Vidal, who swept up Evra's low cross only to rifle the ball wide with Toro goalkeeper Jean-Francois Gillet left short-handed.
Giampiero Ventura's men still looked full of intent when play resumed and, in the 52nd minute, Quagliarella rattled a post after sliding in to connect with Amauri's cross.
Peres drifted the ball for Amauri to try his luck with a header that Storari blocked before the defender broke into the box on the left to rasp a dangerous shot across the face of goal.
The Italian champions remained second-best inside their own stadium but Carlos Tevez soon wriggled free to lead a rare Juve charge that saw him scoop over the bar.
They were dealt a double blow shortly before the game entered its final 10 minutes. First, Vidal tapped home from six yards only to be ruled offside, and then Lichtsteiner was sent off.
In a show of frustration the Switzerland international - booked earlier on for dissent - went in hard on El Kaddouri in the Torino box and received his second yellow card of the evening.
That flaring of tempers lit the touchpaper on five frantic minutes to close out a memorable match.
Torino looked like they had edged the final exchanges, with Amauri only denied the chance to pick his spot by a brave and crucial intervention from Giorgio Chiellini.
Yet despite their manful performance, the point - and an opportunity to force an historic draw - slipped away from them right at the death.
Only seconds remained on the clock when the ball spilled to Pirlo on the edge of the D - the veteran playmaker took one step forward before powering a screamer into the bottom corner.
