Eric Kinder hailed the best result of his coaching career as the development squad reached the final of the Under-21 Premier League Cup.
The Under-21s beat defending champions Reading 2-1 after extra-time on a dramatic night at Leigh Sports Village.
Sam Lavelle headed Rovers in front at the midway point of the first half, but a lively Reading side deserved their equaliser from Tariqe Fosu eleven minutes from time to send the tie into extra-time.
Bradley Bauress fired Rovers back in front from the penalty spot after Lewis Mansell had been fouled, but even though the home side rode their luck in the closing stages as the Royals twice struck the woodwork, they held on to claim a spot in the two-legged final against either Southampton or Derby County.
"It is brilliant, they worked their socks off tonight," the coach told Rovers Players.
"We asked them to stand up and be men and that is what they did, I'm proud of every one of them.
"I'm delighted, it is probably the best result of my coaching career. I got to the quarter-finals of the FA Youth Cup with Carlisle but this tops it. I'm absolutely delighted to be in the final.
"To get this result tonight means everything. We've got to the final so now we've got to go and try and win it.
"I keep repeating it, but we've a young side in a hard league, but if we can get a couple of these into the first team inside the next two years then all these league results and all the bad nights that we've had will have been worth it."
The Under-21s are quickly back in action, they face Brighton & Hove Albion at Ewood Park this Monday night, kick-off 7.00pm.
