At the end, it was the re-emergence of an old goalscoring hero in John McGinn that lit up the Hampden night, but in every other sense this was the dawning of the age of Doak.
Young Ben, 19, fearless and flying down Scotland's right, against Josko Gvardiol, the renowned £77m man from Manchester City. No contest.
The margin of Scotland's victory was tight. The margin of Doak's superiority was vast.
Doak was electrifying long before the endgame. The Liverpool teenager, on loan at Middlesbrough, was a whirling dervish, a human blur taking the fight to Croatia.
