Badshot Lea co-manager Gavin Smith admitted Alton were the better side in Tuesday night's Aldershot Senior Cup semi-final, despite his team beating the Brewers 3-0 at Westfield Lane.
Connagh Wilks headed the Baggies in front in the 18th minute from Mac Ford's free kick.
Mal Thomas made it 2-0 on 78 minutes when he finished from the edge of the box past Alton keeper Lewis Mees.
Thomas completed the scoring on 80 minutes when he cut inside from the left and fired a fine finish past Mees into the far corner.
Smith was disappointed with his side's performance, but was full of praise for Alton's display in last night's semi-final.
"I think they'll be disappointed that they haven't got something out of the game," said Smith.
"They showed more desire, more energy, more fight, and they played better than us.
"You think how have we won that game of football from being second best in most departments, apart from defensively I thought we were strong in terms of defending set pieces, and we had a bit of quality in the final third.
"Alton wanted it more than us, but we've somehow sneaked into a final. We'll take it. We can't be brilliant all the time.
"I don't want to take any credit away from Alton, though, because I thought they were better than us – especially in the first half.
"It looked like a set piece was the only way we going to score, because we didn't play well. We didn't look like opening them up and scoring goals.
"We could have scored another couple from set pieces, and the difference was we defended our goal better than they did theirs."
The Baggies will face Isthmian League side Westfield at Aldershot Town's EBB Stadium in the Aldershot Senior Cup final on Tuesday, May 9 (7.45pm).
