Sheffield United were crowned title winners of the U18 Professional Development League Two (North) on Tuesday after a thrilling victory over Sheffield Wednesday at Middlewood Road.
It was a tale of two Hirsts at S6, but it was United's Horatio not Wednesday's George, son of former Owls favourite David, that was the matchwinner after Hallam had restored parity following Jordan Lonchar's first-half opener.
And Lead Coach Derek Geary heaped praise on his youngsters in the aftermath of the success.
He remarked: "This group of lads have been excellent all season and this is their deserved reward.
"They have all worked hard, developed and improved from when we started in pre-season and I'm delighted that they now get the chance to experience what it is like to win something in the game.
"We will enjoy the moment but remain focused between now and the end of the season as we look forward to the play-offs against the teams from the south section."
In front of a health crowd and a sun drenched Middlewood, it was Wednesday who were out of the traps the quickest, with Hirst hitting the post early on. The striker then turned provider as the Owls went in front, with LONCHAR firing home past Warhurst.
United's response to going behind was positive though and Mallon almost levelled immediately. The only a last-gasp tackle from Cook denied Smith shooting at goal before the break.
The Blades picked up from where they left off upon at the restart and this time Williams produced heroics to deny HALLAM, but in the next attack, United's leading goalscorer wasn't to be stopped as he fired home an equaliser into the bottom corner.
The visitors were now firmly in the ascendency chasing the victory needed to secure the title and after an 82nd minute scare at one end that elusive goal came United's way at the other, with HIRST sliding home Smith's cross after excellent build-up play involving substitutes Hawkes and Stewart.
United safely saw out the remaining four minutes plus injury-time before the celebrations could get underway.
Blades: Warhurst, Charlesworth, Brown, Cantrill, Ford (Hawkes 66), Graham, T. Smith, Gilmour, Hirst, Hallam (Stewart 78), Mallon (Ferguson 86).
Unused: Perryman, Parkhouse.
