A double from Richard Wood was enough to spark a promotion party among the 15,000 Millers fans who had followed their side to Wembley.
In beating Paul Hurst’s Shrewsbury Town under the Arch, Rotherham ensured all three clubs relegated from the second tier a year ago bounced back at the first attempt.
“We have had an amazing season,” said Warne, after his players had prevailed after extra-time. “I told the lads in a meeting beforehand, ‘Even if we don’t win today then you should be immensely proud of what you have achieved’. But we did it and that makes me proud.”
Wood’s double meant Warne, the club’s former fitness coach, achieved the notable distinction of winning promotion in his first full season as a manager.
The 45-year-old said: “Winning here is made extra special by my kids being at an age when they know what is happening. My dad, bless him, is still hanging in there so got to see it. That means a lot.
“Plus, if you go to work with your best friends, you are pretty blessed.
“For those three reasons, this win is more special for me.”
