Andy is through to his second Grand Slam final after coming from a set down to beat Marin Cilic, 3-6 6-4 6-4 6-2 at the Australian Open.
He'll now face either Roger Federer or Jo-Wilfried Tsonga in Sunday's final, somewhere no Brit has ventured since John Lloyd in 1977.
He goes there having arguably conjured up not one, but two shots of the tournament; the first turned the match, the second was the icing on the cake.
So another class performance from Andy, against an opponent who is dangerous even when down, and especially so when in front.
Such was the case here as Cilic dominated the early exchanges to take the first set, and fancied his chances with 0-30 on Andy's first service game of the second.
But the definitive turning point arrived three games later at break point on the Cilic serve: Andy chased down a net cord and cut out a pass before looking the odds on loser as a lob sailed over him.
Cilic waited at the net for the easy put away, only to watch in horror as Andy passed him from way past the baseline, back to the net.
As winner's go it was far bigger than just a break point, it changed the match; Andy's engine had faltered at the start, but here it was revving at a level Cilic wouldn't respond to.
